# Welcome to CrownCAD 2026 R1


  CrownCAD 2026 R1 incorporates extensive user feedback to fully meet your design requirements. In terms of usability, we are committed to enhancing user experience; in functionality, we continuously add essential commands that help you quickly complete product design and development tasks.

Main Enhancements:

Sketch The sketch dimension tolerance types now include: "Basic," "Fit," "Tolerance and Fit," and "Fit (Show Tolerance Only)."
Dimension support for reverse direction, allowing the relative positions of the annotated elements to be swapped.
When generating multiple fillets with the same radius, allow only one fillet annotation to be displayed.
Support automatically adding dimensions and geometric constraints to drawn sketches.
Features Support stretching/rotating a selected local area of a sketch.
The array/mirror command now supports selecting array/mirror features as source features.
Stretch cut now supports removing multiple solids in a single operation.
Added support for creating ANSI Inch (imperial) thread holes.
In the Mirror command, a new "Copy" option has been added to control whether mirroring or symmetry effects are applied.
Surfaces&Curves Added conic curve command.
Added the Intersect command, used to create curves/points at intersection locations.
Added the isoparametric curve command, used to create curves on a surface that align with the isoparametric direction.
Added the spine curve command, used to create curves perpendicular to a sequence of ordered planes or planar curves.
Added the Fair Curve command, used to make existing curves smoother.
Sheet Metal Edge flange feature supports mirroring.
The Stretch Cut command now includes a new "Equal to Thickness" option, allowing you to quickly create cutouts with a consistent thickness matching the sheet metal.
Added rectangular-oval type for edge relief slots.
Assembly Added cam mate, rack and pinion mate, path mate, and linear/linear coupling.
Data Conversion Support reading MBD annotations from STEP AP242 (.step) files; Support opening CrownCAD models in NX and reading MBD annotations from the original model.
Support reading MBD annotations from NX models in CrownCAD.
Added support for automatic conversion when importing assembly compressed packages.
BOM 【BOM Tools】 supports counting piping BOM information.
Apply Added right-click quick picking feature, supporting rapid selection of edges/lines/faces in models or sketches.
Evaluate Added input diagnostics feature, supporting repair of invalid surfaces and seamless stitching of repaired surfaces into closed ones.
Support picking point cloud models for measurement.
Library New standard component types and improved specifications have been added to the standard parts library.
Optimize knowledge base entry and exit.
Motion Analysis Added motor, force/torque, gravity, and result visualization features.
Drawing Support inserting annotations corresponding to weld features from 3D model files into engineering drawings.
Support linear array of existing annotations; support circular array of existing annotations; support setting title block annotations.
Support picking sketch boundaries to fill hatching; meanwhile, expand the range of model faces that can be filled, and support hatching on non-planar model faces.
Support for picking dimension values when creating a datum.
Added the feature to align engineering drawing views, supporting the alignment of auxiliary views, section views, and other views with angles to the engineering drawing views.
Setting System Settings - Document Properties - Annotations: New options for attachment position, horizontal leader lines, and trailing zero value settings.
Support individually setting different fonts for "Part Number, Datum, Geometric Tolerance, Datum Target, Notes, Revision Cloud, Surface Roughness, Welding Symbols" under annotations in system settings.
New configurable options added in Document Properties - Dimension Settings, supporting more detailed customization of dimension styles.
Allow direct renaming of documents within the project document, without having to exit the document and return to the project management interface for renaming.
In Document Properties - View - Section View, a new group for setting arrow styles and line styles has been added.
Piping Added connection point and route point functions, allowing users to define connection positions for pipework components and specify their placement along the pipeline.
Added the grading rule feature, used to create and manage size and attribute rules for pipes, enabling pipe creation based on grading rules.
Supports creating three types of pipes: straight pipes, bent pipes, and flexible hoses. Users don't need to draw pipe profiles. By simply specifying the pipe type, parameters, and grading rules, the system can automatically generate the pipes.
Added piping components library feature, supporting storage and retrieval of piping components.
Support generating piping sub-assemblies within assemblies.
Support controlling the entry and exit of piping sub-assemblies.
Support controlling the activation of piping routes.
Support creating route lines for piping.
Added the command to create hose path lines.
Allow manual addition of bend angles between adjacent route lines.
Supports automatically drawing route lines between two selected connection points.
Allow adding and removing constraints for route lines.
Allows modifying parameters of route lines, such as dimensions, orientation, and bend angles.
Support deleting already drawn route lines.
Support displaying and controlling the default route parameters for piping.
Support routing pipes along a path, placing pipes onto the path.
Allow editing parts placed within piping, and adding modeling features.
Allow editing parts placed within piping, and adding modeling features.
Support editing the dimensions and specifications of already created pipes.
Support breaking a single pipe into two connected pipes.
Support merging two coaxial pipes into a single pipe.
Added filtering options for connection points and route points in the selection filter. After enabling the filter, only corresponding elements can be selected.
New piping-related options added in system settings.
