# Extruded Cut
When stretching a sketch, partially excise the stretched entity that intersects the excision body.
Click the toolbar 
to open the Stretch Cut Command dialog box, and its command interface is shown in the following figure.
- Select a sketch or plane to sketch :
Pick a sketch profile to extrude the cut.
Pick a plane/datum plane, enter the sketching state, and after sketching and exit, automatically fill the drawn sketch into the pick box.
Note：
Sketches can contain multiple closed areas that do not intersect, distinguished from the Stretch Boss/Base command
- Offset: After checking, the offset mode drop-down box appears, and the stretching starts from the current sketch datum plane to the specified position. If necessary, point reverse.
- Bias method
(1) Distance: Enter the distance in the open Distance Modification dialog box and the stretch starts on a datum equidistant from the current sketch datum.
(2) From Surface/plane/datum: Pick up the starting surface in the open starting surface pick box, and the stretch is created from the selected surface and throughout the excision body.
【 Surface range: The plane and the base surface have an infinite range of action, and the surface's range of action cannot be extended 】
- Direction：After checking, open the direction pick box, the direction vector stretches the sketch in the direction perpendicular to the sketch outline, and if not selected, the direction is stretched according to the sketch method.
Note：
Direction vectors can be sketch lines, two points, solid edges, or reference reference lines.
Method：There are four ways, namely “given depth”、“form to surface”、“symmetry on both sides”、“one-way penetration”，different ways will have different corresponding parameters, preview different stretching effects.
Draft：Stretch while forming a draft slope at a given angle.
Note：
Default outward draft, inward draft point reverse.
Direction 2：Stretch in two directions at the same time with the sketch plane, there are three ways to stretch, namely “given depth”、“form to surface”、“one-way penetration”，and different ways in direction 1 are combined to preview different stretching effects.
Thin-wall feature: After checking, the outline of the sketch can be thickened to generate a thin-walled entity and then excised.
- When the selected outline sketch has open loop lines, the thin-wall feature is checked by default;
- When all the selected contour sketches are closed-loop lines, thin-wall features are not checked by default;
- Excised body: the body being excised by stretch.
Note：
The excised body should intersect the stretched body.
# Blind
Depth： Stretches from the sketch plane to one side, adjusting the depth of the stretch by entering parameters or dragging the black arrow in the viewport. If necessary, point reverse.
Example： Given a depth mode, the excision effect is shown in the following figure:：
# Up To Surface
- Face：Select a face to extend to.
Note：
- Faces can be solid surfaces, planes, surfaces, or datums；
- The cylindrical or surface range needs to be larger than the sketch outline.
- Reverse：After the point is reversed, it is stretched in the opposite direction in the positive direction.
Example： In the shape-to-face mode, the extrusion and excision effect is shown in the following figure.
# Mid Plane
Depth：Symmetrically stretches to cut equal depths in both directions, using the sketch plane as a datum.
Example： The extrusion effect is shown in the following figure under symmetry on both sides.
# Through All
One-way through the current geometry, and when the point is reversed, it is extruded in the opposite direction of the preview direction.
Example： In the one-way penetration mode, the excision effect is shown in the following figure.
# Up To Next
The resulting stretch cut feature automatically starts at the next plane outside the sketch until it runs through the entire cut body.
Example: Shape to the next side of the way, stretch cut effect as shown in the figure below.
- Dialog box control description:
(1) Method: You can select Shape to Next. (This mode occurs only when there is a next side that meets the condition)
(2) Next side: The sketch is outside the solid outline and has a solid surface (either hidden or displayed) on which Boolean operations can be performed.
# Two-Direction
- After checking direction 2, use the sketch plane as the datum to perform a stretch cut in the other direction.
Note：
When the tension method is selected for symmetry on both sides, there is no direction 2 option
- There are three ways to “give depth”、“form to surface”、“one-way through”，and the same direction1.
Example： The excision effect after checking direction 2 is shown in the following figure.
# Offset
When checked, the Biased Mode drop-down box appears and the stretch starts from the current sketch datum offset to the specified position. Dot reverse if necessary.
- Bias method
(1) Distance: Enter the distance in the open Distance Modification dialog box and the stretch starts on a datum equidistant from the current sketch datum.
(2) From Surface/plane/datum: Pick up the starting surface in the open starting surface pick box, and the stretch is created from the selected surface and throughout the excision body.
【 Surface range: The plane and the base surface have an infinite range of action, and the surface's range of action cannot be extended 】
Example：
- After setting the relevant parameters, the bias-distance effect is shown below.
- After picking up the bias surface, the bias-distance effect from the surface/surface/datum is shown below.
# Thin Features
See Thin Features for details.
# Flip Side to Cut
When it is not possible to remove the solid using an open contour or when you need to retain another part on one side, this option can be utilized to enhance design efficiency.
Closed contour: By default removes the area inside the closed profile. When 'Reverse Cut' is selected, it removes the area outside the closed profile, and the outer scope is unlimited.
Open contour: When selecting an open contour drawn on a solid face, if the contour divides the selected cut body into two parts, you can avoid using 'Thin Wall Features' and directly remove one side. When 'Reverse Cut' is selected, the other side will be removed.
Note 1: When selecting an open contour that is not drawn on a solid face, the reverse cut functionality cannot be used.
Note 2: When 'Thin Wall Features' are selected, the 'Reverse Cut' option is not available.
# Normal Cut
When performing an extrusion cut on a sheet metal body, selecting the orthogonal cutting option allows you to quickly generate a model aligned with sheet metal characteristics.
How to use:
1）Create the cut sketch and sheet metal body.
2）Open the Extrusion Cut command and select the sketch and sheet metal body;
3）Check the Orthogonal Cutting option;
4）Click OK to generate the cut feature with surfaces orthogonal to the sheet metal.
Note：
- The Orthogonal Cutting option is available only when performing a cut on a sheet metal body.
Select "Optimize Geometry" to smoothly connect the projections of the upper and lower surfaces of the removed portion, facilitating subsequent operations such as machining.
