Note：

① Support the selection of edges of surfaces/entities, sketch non-reference lines, space curves;

② Only a section of the line in the edge line or sketch line can be picked up, rather than the entire outline;

③ Both edges should be either open loop or closed loop.

Bridging Curves

  New bridge curve feature, support to select two points on a line or surface to generate a bridge curve. Bridge curves up to support G3 continuous.

1. Point requirement

• Points should be taken from a line or surface, not individual points.
• Lines include: sketch lines, space curves, surfaces/solid edges, open or closed loops.
• Surfaces include: surfaces of curved surfaces/solids, closed or open.

2. Continuous mode

• Contact (G0) : The bridge curve makes contact with the line/surface where the point is;
• Tangent (G1) : The bridge curve is tangent to the line/plane where the point is located;
• Curvature (G2) : The bridge curve is tangent to the line/plane on which the point is located and the curvature is continuous;
• Flow (G3) : The bridge curve is tangent to the line/plane on which the point is located and the curvature curve is tangent and continuous;

Lattice modeling

  Quickly create a "lattice model" consisting of multiple "lattice units" distributed according to certain rules in the part document.

Creation process

1. Getting Started

  Toolbar switch to lattice module, click the icon to open the lattice modeling command, and then pick up the target entity;

2. Set lattice parameters.

3. Click Preview to generate a preview with the currently set parameters.

4. Click OK to generate Lattice Modeling features and grid entities.

Parameter Description

• Cell Type - Group: Set the style and size of the lattice cell.
  • Shape: Sets the style of the lattice cell;
  • Scale: Choose how to resize the lattice cell, optionally "uniform, non-uniform";
    • Uniform (default) : the lattice unit is always a positive cube. Select this option to modify the "size" parameter and adjust the side length of the cube.
    • Non-uniform: The length of the lattice unit in the XYZ direction can be set separately, and the value of the "XYZ direction" parameter can be modified separately by selecting this item to adjust the side length of the lattice unit in different directions.
• Lattice change - group: make the whole composed of lattice cells move/rotate in the target entity region.
  • XYZ distance: Separately control the distance of the translation in the XYZ direction;
  • XYZ Angle: the Angle of rotation around the XYZ axis is controlled separately;
  • Reset: Click this button to restore the lattice position and distance Angle values to their initial state;
• Solid state - Group: Set the solid volume of the lattice, such as the thickness of the cylinder.
  • Distribution: Control the solid state distribution mode, the current version can only select "uniform";
  • Uniform mode: the solid state value of the whole model is consistent, and the setting item is "solid state and sliding control".

Special note

① The "lattice" feature, like other features, supports re-editing, deleting and other operations;

② The "lattice" features have a sequential relationship with other features. When the reference features (such as the target entity) are modified, the "lattice" features change with the corresponding "grid model". When the reference feature is deleted manually, the lattice feature will be deleted together as its sub-feature;

③ The "lattice" model is the grid model, which is derived in the same way that the ordinary grid model is derived.

Structural simulation

  In the CrownCAD 2024 R1 release, the first structural simulation module allows you to perform structural simulation calculations in part documentation.

New example

Switch the toolbar to the "Simulation" module, click the icon to create a new example and enter the name of the example:

Set the entity you want to analyze

① When multiple entities are included in a document, all entities in the document are analyzed by default;

② By right-clicking an entity in the simulation panel, you can set whether to analyze it or not;

③ Then edit the model to generate a new entity, the new entity is the entity to be analyzed by default;

④ The entity set to not analyze is not visible when the example is activated, and it does not need to consider whether it has added material, external load, and boundary information during calculation.

Set Material

  Select the entity in the simulation panel, click Apply Material and set the selected entity to the selected material; After setting, you can view the material set by the current entity in the simulation panel.

Note：

①When the example is created, each entity inherits its material in the part document by default. Entities that do not have a separate material set inherit the document material.

②After the example is created, the material of the entity in the example can be modified by the "Apply material" command of the simulation module.

③The same entity can set different materials in different examples. Setting materials in examples does not affect the calculation of the material of the entity.

④A material must be added to each entity to be analyzed.

⑤Do not select the entity, directly use the application material function, will uniformly modify the material of all the entities in the example.

Setting external loads

  Start the external load command, and after selecting the load surface, add an external load to the entity. Right-click the external load of the simulation panel, you can set the visibility of the load arrow in the viewport.

Set boundary constraints

  Click , start the Boundary constraint command, select the fixed surface, add the boundary constraint to the entity. Right click on the boundary constraint of the simulation panel, you can set the visibility of the constraint arrow in the viewport.

Generate a grid

  Click to start the Generate Grid command, or right click on the grid in the simulation panel - Generate Grid and click OK after setting the precision in the dialog box.

Note：

①You can manually generate a grid for the entity before running the example;

②When running the example, if the grid has not been created yet, or if the grid is inconsistent with the current entity, the grid is automatically created or updated with medium precision.

Run the example

  Click , execute the command to run this case.

Note：

The example cannot be paused during running, and other operations are prohibited.

View Results

• The Stress result is displayed by default after the calculation is complete.
• Double-click on "Stress/Strain/Displacement" in the simulation panel to toggle the display results.

Deformation results

• By default, the model will be deformed, and the degree of deformation will be increased in proportion to observe the displacement effect.
• Click on the command bar to turn on or off the model deformation effect.
• Right-click the result of "Stress/strain/displacement" in the simulation panel, click Set, and change the setting mode to "Custom", you can modify the amplification ratio of deformation effect.

• Click on the command bar's so that the result shows only areas of the model that match the parameters.

Generate reports

• Click on the command bar to automatically generate and download a Word document type result report.
• The report generation process cannot be suspended, and other operations are prohibited.

Activate and exit the example

• Automatically activate after creating a new calculator.

• Double-click the example in the simulation panel, or right-click the example and select the "Activate example" option to activate the example manually.

  

• Right-click an already activated example and select the "Exit example" option to exit the currently activated example. It is recommended that you exit the example before editing the model.

• Manually switching between "Feature Panel, View Panel, Simulation panel" does not affect the activation state of the example, that is, switching the panel does not cause activation or exit of the example.

• After the example is created, modifying the model does not affect the generated example. You can activate the example to view historical data, or reset the example parameters and calculate the result.

Optimize viewport rotation operations

Custom rotation point/axis

  Click the mouse wheel on the corresponding position of the viewport to set the rotation center/rotation axis.

1. To set the rotation center

  Click the mouse wheel on the following table element and the mouse pointer changes to the "rotate around the point" style with the corresponding element highlighted. At this point, hold down the wheel to rotate, and the Angle of view rotates around the corresponding element.

Type of element	Supporting elements	Correspondence center
Point	Solid/surface vertices, Sketch line endpoints, Sketch drawing point, Reference points, Dots	Point
Curves	Solid/curved edges, Sketch line, Space curve (non-linear shape)	The starting point of the line

2. To set the axis of rotation

  Click the mouse wheel on the following table element and the mouse pointer changes to the "rotate around axis" style with the corresponding element highlighted. At this point, hold down the scroll wheel to rotate, and the Angle of view rotates around the corresponding axis.

Types of elements	Supporting elements	Corresponding axis
Straight lines	Solid/surface edges, sketch lines, reference axes, space curves (straight lines)	Line
Arc line	Solid/curved edges, sketch lines	Lines perpendicular to the plane over which the circle is located
Cylindrical surface	Solid/curved cylindrical surface	Axis of cylinder
Plane	Solid/curved plane-like surface (not including datum)	The line perpendicular to the face across the plane enclosing the center of the box

Note：

① After setting the rotation center or rotation axis, perform a rotation Angle operation: automatically cancel the rotation center or rotation axis, the mouse restores the default style;

② After setting the rotation center or rotation axis, do not rotate the Angle of view operation, directly perform other operations A, automatically cancel the rotation center or rotation axis, the mouse restores the default style, and perform operation A.

Optimize the rotation focus

  Place the mouse over the model, at which point the Angle of view is rotated, and the intersection of the mouse pointer with the model will be used as the center of rotation. You can still use this feature when starting any command, such as turning on the stretch boss command. In previous versions, this feature was not supported when the command was started.

Optimize dialog box display

Support dialog box adjustment/recessive

1. Dialog box resizing

  Support horizontal, vertical drag dialog box border, in order to adjust the dialog box size.

2. Support dialog box visibility

  When the command dialog box is opened, the "Dialog box hidden" button is displayed in the upper right corner of the feature panel and the upper left corner of the dialog box; Click the "Dialog box display and hide" button to switch the dialog box display/hide state;

Display command dialog box	Hide the command dialog

Note：

  When the height or width of the dialog box is already the minimum value, continue to drag the dialog box in the direction of the smaller size to hide the dialog box, the hiding effect is the same as clicking the dialog box hide button.

3. The subsidiary dialog box supports independent adjustment of position and size, such as [welding symbol] ：

Add "Apply" button

Add an "Apply" button to the command dialog box, using the rounded corner command as an example to illustrate the difference between the "Apply" and "OK" buttons:

• Application：Do not close the dialog box after creating the rounded corner, and can be created continuously.
• Ok：Create rounded corners and close dialog box.

Optimize the pick operation

Pick up points quickly

  When picking up a point in the part, hover your mouse over the point a little and "... "appears in the lower right corner of the pointer. ", click the left button to pop up the "Quick pick up" dialog box, the dialog box shows all the points that coincide together here, you can click in the dialog box to precisely pick up the required points.

Unified box selection operation

1. Assembly

  Hold down the left mouse button in the viewport to move the frame selection, the mouse from the left side of the viewport to the right frame selection, need to put all the instances in the frame selection range to pick up; When the mouse is selected from the right side of the viewport to the left side of the frame, as long as the instance has elements in the frame selection range, the instance is picked up.

2. Parts

• Without starting command, box select can pick up surface/edge of surface/solid/grid entity. When all the edges of a surface are selected, pick up only its surface and not its edges.
• Start the command to pick up elements for a pickup frame that supports multiple selections. You can select the pickup in the viewport frame to pick up only the elements supported by the pickup frame. For example: [Delete the face] function can only select the face, but not the edge line.

Optimize the feature panel display and right-click menu

Align element names with features

  Optimize the display names of entities, curves, surfaces, and meshes in the feature panel so that the names are consistent with the operation feature names in the last step.

  Example: in the Chinese state, the feature name of the last step of an entity is "rounded corner 1", then the entity is called "rounded corner 1"; The same is true for curves, surfaces and grids.

Perfect the right-click menu

Set appearance/material

Support the assembly environment to set the look

  Setting appearance in assembly can set the appearance of "instance, solid/surface, surface".

Note：

① Modify solid/surface appearance and surface appearance in assembly, directly change the solid/surface appearance and surface appearance in the part.

② Setting the instance appearance in assembly changes the appearance of the entire part instance displayed in assembly, but does not change the appearance of the part itself.

③ Appearance priority: Instance Appearance > Surface Appearance > Solid/Surface appearance.

Add appearance library

  Add appearance library to provide preset appearance, such as glass, wood, etc. Each appearance corresponds to a set of appearance parameters, including information about color, transparency, etc.

  How to use：

  ① Click on the sidebar on the right to open the appearance library.

  ② Hold down the left mouse button and drag the preset appearance onto the element you want to set the appearance on.

  ③ Release the left mouse button and select which level you want to set it to in the menu that pops up to complete the setup.

Sketch Drawing

2D Sketch

Equation curve

  In this tool, new equation library and save custom equation function, and support to edit the created equation curve:

1. Equation library

  You can select an existing equation in the library, or add a custom equation to the equation library for quick subsequent calls;

• Examples of calling equations：

Double-click an equation in the equation list to fill it into the left Equation dialog box and preview it in the viewport:

Equation parameters can be adjusted to generate a new equation curve:

2. To save a custom equation:

  After filling in the equation, click to add the equation to the equation library, and return to the corresponding list according to the equation type;

3. Edit the equation curve：

  Click the created equation curve, the "Equation curve properties" dialog box pops up, you can adjust the equation or other parameters again;

Ellipse/ellipse arc

  New ellipse/ellipse arc function, generate ellipse outline in sketch by defining Angle, radius 1, radius 2, center of circle coordinate parameters.

Note：

① After creating the finished ellipse, drag and drop can only change the position, can not change the size and Angle of the ellipse, the size of the ellipse can only be changed by editing the size.

② If there are any size or geometric constraints in the ellipse, it is not supported to continue to adjust the size in the property box.

Dimensional labeling

Marking symmetrical dimensions

  This action helps you label points, lines, circles, arcs to 2 times the size of the center line/guide line in the same sketch, and supports switching sizes.

1. Marking symmetrical dimensions：

① Label two elements with the "size Constraint" command, one of which is the center line/guide line; ② If the size number is placed beyond the center line, it will be labeled as symmetrical size;

2. Change size type：

  After generating a symmetrical size, change the size to a radius size or a diameter (symmetrical) size through the properties panel for the size - Diameter/Radius.

Label the 0 value dimensions

External Reference

1. Reference silhouette/round edge line to add constraints:

  When adding constraints, support to directly select the external element's silhouette or circle edge line for annotation, without first projecting.

Add geometric constraints to side projection contours	Add dimensional constraints with side projection contours

2. Supports direct labeling of the plane perpendicular to the current sketch plane without the need for a projection first.

Offset

  Expand the support type of elements to be offset, can directly select the elements outside the sketch for offset, and keep the linkage.

Note：

① Optional other sketch lines, solid/surface edges, solid/surface surfaces (equal to picking up full edges); ② When the selected element cannot be projected on the current sketch surface to generate a line that can be migrated, the prompt "cannot migrate this element" is displayed; ③ Automatically add dimension labels and "offset" constraints between the offset line and the selected element (circle and curve elements are not supported).

Transition boundary

  Support the choice of spline surface conversion boundary, repair lofting boss, spline curve conversion effect.

1. Spline surface conversion boundary:

2. Example of lofting boss, spline curve conversion effect:

Applicability

Annotate overall scaling for the first time

  When the length or distance in the sketch is first annotated, the elements and perspectives within the sketch are automatically scaled around the origin of the sketch, and they look the same as before the annotation, but the length/distance of the relevant elements have changed.

Pick Up Optimization

1. Support for picking center points:

  In the sketch environment, when executing the sketch drawing class command, you can directly pick up the center of the sketch circle/arc edge line, and automatically add coincidence constraints. There is no need to convert the boundary first and then pick up.

2. Support for pre-selection of elements:

  Sketch state, do not open any command, highlight when the mouse points to the face, line, point, sketch and support picking; After pre-picking elements, open the corresponding sketch command:

• If the command supports pre-picking elements, then automatically fill the corresponding pick box;
• If the command does not support pre-picked elements, when clicking other elements in the viewport, unhighlight and select the pre-picked state;

3D sketch

Symmetric constraints

  Adding symmetric geometric constraints to the 3D sketch environment adds symmetric constraints to two elements relative to a plane.

Applicability

Automatic direction judgment

  In 3D sketch environment, the direction of the plane will automatically switch to the most closely parallel view direction when the view direction is almost parallel to any plane of the XYZ coordinate system.

  After the automatic switch, you can still manually switch to other standard three-view directions using the tab key.

Parts and Features

Support for multi-profile drawing

  Now, the stretch convex plate function supports stretching multiple non-intersecting contours at one time. With this foundation, you no longer need to perform a dissection operation of text before stretching the sketch text directly.

Note：

• Entities created by stretching multiple Outlines at once appear to be separate from each other, but they are counted as one entity in the system.
• This type of entity with multiple disconnected parts is not allowed to be removed from the shell.
• Pick up the sketch line in the viewport and the system will stretch the closed outline where the sketch line is located. If multiple Outlines are included in a sketch, you can use this feature to specify which Outlines to stretch instead of having to stretch all the Outlines of the entire sketch. This function is applicable to stretch bosses, stretch excise commands.

Fillet radius parameters support variables/equations

  When creating a multi-radius fillet, you can enter variables or equations in the multi-radius input component; You can edit the variables or equations after they are created.

Hole - anchor point enhancement

  In this version, the selection method of the hole anchor point is mainly enhanced: when selecting the hole center point, the whole sketch can be directly selected or the sketch can be quickly "drawn".

1）The hole center point supports the selection of the entire sketch:

2）Quick "sketch" when elements are not picked up.

  Click "Draw Sketch" to create a new sketch on the selected solid face to punch and enter the sketch, exit the sketch when it is finished, and fill the entire sketch to the "hole Center Point" pick box.

Add a Center of Mass

Support for centroid generation in parts/assemblies, support for centroid reference points generation in parts.

1）Centroid creation method:

By clicking the command "Center of Mass" or "Quality Properties" - "Show center of mass", you can create the center of mass; There can only be one center of mass in a document.

2）How the centroid reference points are created:

After the centroid is generated, right-click the centroid feature in the feature panel and click the icon to create the centroid reference point. You can have more than one centroid reference point in one document.

3）The difference between a centroid and a centroid reference point:

• The centroid represents the final centroid position of the entire document. This can be generated in assembly and parts
• The centroid reference point represents the centroid position in the modeling history of the model up to the time the centroid reference point feature was created. It can only be generated in the part.

4）In most cases, the position of the centroid point and centroid reference point is updated instantly as the model changes. In some special cases, it may not be possible to update automatically, at this time, the update button will be displayed after the centroid, click to manually complete the update.

Add Save entity

  New Save Entity feature that allows you to copy and save entities from one part document to the new part document. This feature also allows you to insert these new part documents into a new assembly document.

1）To save to a new part document：

  Uncheck "Generate Assembly Document" to copy and save the selected entities to the new part document separately.

2）To generate the assembly document：

  Check "Generate Assembly Document" to create an assembly document directly and insert all the selected entities into the assembly document as new parts.

3）Other save options instructions

• Copy appearance Settings: Apply the appearance of the entity in the source document to the new part entity;

• Copy Material: Applies the material of each entity in the source document to the document material of the new part.

  • When transferring an entity with a separate entity material set, copy the entity material onto the document material of the corresponding new part.
  • When transferring an entity without a separate entity material, if the source document has a document material, copy the document material to the document material of the corresponding new part;
  • When transferring an entity that does not have a separate physical material set, if the source document does not have a document material set, the document material for the new part is not set.
  • Transfer the material to the document material of the new document, rather than the physical material, so that the material properties can be read through the material specification table during assembly.

• Skip Duplicate entities: Check this, "Array-generated entities, Duplicate Entities in Weldparts Cut List items" will generate only one part document, avoiding the need to create multiple duplicate documents.

Assembly design

Optimized assembly image

The assembly image parts follow the left hand coordinate system, and the new "create new document" option supports the creation of different image effects.

Note: Checking the option will generate a symmetrical part document.

Check	Untick

New replacement parts function

Added Replacement parts function, which allows you to quickly replace parts or sub-assemblies in the assembly. After replacement, the new part position coincides with the original part reference position.

Enhanced TopDown external reference

When editing parts in assembly, part features can pick up elements of other parts (points, lines and surfaces) as feature directions, termination surfaces, etc.

The features and picks that support references to other parts elements are listed in the following table:

	Bend corner	Bend Angle	<bend-angle>
	Supplemental Angle	The supplementary corner of the bend corner	<bend-complementary-angle>
	Bend radius	Bend radius	<bend-radius>
	Bend order	Bend order	<bend-order>
	Bending coefficient	Bending coefficient	<bend-allowance>

New Sketch projection

Support the sketch of the part model displayed in the engineering drawing view, and the displayed sketch can be dimensioned, which allows you to mark the frame size of the welded part more intuitively.

• The sketch can be dimensioned, and the annotation effect is the same as the annotation model edge line and the driven size;

• When the view is generated, the default implicit state of the sketch is as follows:

  • 2D Sketch: The sketch plane and 2D sketch parallel to the projection direction of the view are hidden by default when the view is generated, regardless of its implicit state. The implicit state of other 2D sketches is the same as the implicit state of the sketch in the model when the view is generated.
  • 3D sketch: The implicit state of the 3D sketch is the same as the implicit state of the sketch in the model when the view is generated.

• When a view is generated, each view independently records the explicit state of each sketch in that view.

  • The model features in the view panel can be expanded, and the eye icon after the sketch can be clicked for the hidden operation;
  • This operation only affects the hidden state of the sketch in the current view, and does not affect the hidden state of the sketch in the source model and its parent and child views.

Added Reading 3D Explosion View

The assembly engineering drawing supports the generation of the view of the explosion state, and supports the normal marking size, part serial number, etc., on the explosion view.

Note：

① When the assembly is selected, the explosion view of the isometric direction is displayed in the view palette. If there are multiple explosion views, the recently activated explosion view is displayed;

② The explosion view supports custom view, which is generated on the basis of the model after the explosion after modification.
