You can cut a solid model by removing material with a surface or plane. With multibody parts, you can select which bodies to keep.
To cut a solid body with a surface or plane:
Click Cut
With Surface
on the Features toolbar, or click
Insert,
Cut, With Surface.
In the PropertyManager, under Surface Cut Parameters, select the surface or plane to use to cut the solid bodies.

Examine
the preview. If necessary, click
Flip cut to reverse the direction of the cut.
The arrow points in the direction of the solid to discard.

With multibody parts, under Feature Scope, select one of the following:
All bodies. The surface cuts all bodies every time the feature rebuilds. If you add new bodies to the model that precede the cut feature in the FeatureManager design tree and that are intersected by the cutting surface, these new bodies are also rebuilt to include the cut.
Selected bodies. The surface cuts only the bodies you select using the pointer. If you add new bodies to the model that are intersected by the cutting surface, right-click, select Edit Feature, and select those bodies to add them to the list of selected bodies. If you do not add the new bodies to the list of selected bodies, they remain intact.
The solid
bodies you select are highlighted in the graphics area, and listed under
Feature Scope next to
.
Auto-select (Available with Selected bodies chosen). Automatically selects all relevant intersecting bodies. Auto-select is faster than All bodies because it processes only the bodies on the initial list and does not rebuild the entire model. If you clear Auto-select, you must select the bodies you want to cut in the graphics area.
In the example below, only the yellow body (second from the right), was not selected.

Click OK
.
Right-click the surface in the FeatureManager design tree, and select Hide to hide the cutting surface.
The bodies are cut, except for the unselected yellow body, and the cutting surface is hidden.
