Subtract, via Rotation
3-D Standard > Process with sketch > Subt. > Subtract, via rotation
The subtraction is created here by partial or full rotation of a sketch about an axis.
To create a subtraction by rotation, proceed as follows:
- Select Subtract, with rotation
as cross-section motion.
- If the active part is either a main part or an assembly, you can use the checkboxes Include sub-parts and Share feature to specify how subordinate parts are treated during the subtraction.
- Include sub-parts
If this checkbox is active, subordinate parts are included. - Share feature
If this checkbox is active (default setting), subordinate parts are also included. In addition, the system also examines whether a feature log is assigned to the processed parts. If so, the feature log of the subtraction is also assigned to these parts. This means that, in the case of a recalculation of the parts' features, the subtraction will be preserved. If, on the other hand, the checkbox remains inactive, the feature is only assigned to the main part or assembly that is active while calling the function.
- By activating/deactivating the Segment checkbox, define whether you want a partial or full rotation to be performed. In the case of a partial rotation, activate the Dynamic checkbox or specify the start and end angles explicitly.
- If you want to
use an already existing sketch, click the Select sketch
button and identify the sketch.
To create a new sketch, click the New sketchbutton. HiCAD displays the Sketch tab. Create the desired sketch.
- Click the Select
rotation axis
button. Identify the axis in the drawing.
- Click the Preview button to display the result. With dynamic determination of the rotation segment, use the cursor to define the angle of rotation and then press the left mouse button. You can then still correct the angle.
- Click Apply to insert the subtraction as displayed in the preview.

Tips:
- With rotation bodies, it often makes sense to work with special views, as the highlighted edges normally lie in the processing plane.
- To have a rotation axis for rotation processing available quickly, you can create surface axes of cylinders/cones. Note, however, that the axis must lie in the sketch plane.
