Recommended test
Create a measured box, then use a cylinder to cut a hole through it.
- In the current Custom Solid workspace, choose Box and draw its footprint on the ground grid.
- Enter width, length and depth, choose New body and Apply.
- Choose Cylinder, draw on the box top and choose Subtract with the box as target.
- Reverse the depth into the box, extend it through the bottom, inspect the preview and Apply.
Draw a footprint in 3D
Open Custom Solid in 3D mode, then choose Box, Cylinder or Prism. Use the ground grid, a selected work plane or a flat solid face as the drawing surface.
Click two footprint corners, then move the mouse to set depth. Click again to fix it. Drawing a primitive directly on a face uses that face for placement without adding a saved reference plane.
| Tool | Footprint |
|---|---|
| Box | A rectangle with width and length. |
| Cylinder | A circular section sized from a square diameter footprint. |
| Prism | An isosceles triangular section. |
For a different triangle or irregular outline, draw a closed sketch and use Push/Pull.
Set dimensions and direction
Each dimension label shares a row with its input. Enter the values shown by the panel, check the units and orbit to inspect depth. A signed depth controls which side of the drawing plane receives the solid.
Use the Reverse link beneath Depth to switch direction. The nearby ? explains the sign convention. A primitive’s green creation preview continues updating as you move the mouse; sketch and face Push/Pull use the separate outline-first interaction.
Choose the operation
New body creates a separate part. Join, Subtract and Intersect use the shape with a selected Target body. Choose the target in the panel or pick it in the viewport.
A negative depth changes direction; it does not select Subtract. To cut a hole, choose Subtract explicitly and make the cutting shape overlap the target. Review the result before Apply. Cancel or Escape abandons the pending shape.
Continue editing
After applying, use Face Push/Pull to move a flat face, draw another profile on a face, or finish edges. The creation dimensions are not retained as a box/cylinder/prism feature dialog that can be reopened and regenerated. See editing a custom solid for the available operations.
