Cutting the 3D Shape by the Sketch Plane

To make the edges of interest visible you can cut the 3D shape by the sketch plane. This lets you simplify the sketch plane view by hiding the portion of material you do not need for sketching.

Before you begin: Create a simple 3D shape and a plane crossing it in the Part Design app.

  1. Select the plane on which you need to sketch a new profile.


    Once in the Sketcher, you obtain this view which does not show the edges you want to see.

  2. From the App Options panel, click Cut Part by Sketch Plane to hide the portion of 3D shape you do not want to see in the Sketcher.
    You obtain this view without the material existing above the sketch plane. The edges corresponding to the shell are now visible. The edges resulting from the intersection are not visualized and therefore cannot be selected.

    You can now sketch the required profile taking these edges into account.
    Important: When using slice or box tools, the visualization is not correct because the intersection between the two solids is not retrieved properly, i.e. it is not visualized and a cavity appears where materials should be. Only each object specific section results are displayed.
