Performing a trim
A trim refers to the merging of overlapping geometry from one group or component with the geometry from a second group or component (the overlapping geometry is merged with the first selected group or component). Unlike a subtraction, the first group or component remains in the result of a trim operation. A trim can only be performed on two overlapping groups or components. The resulting trim also depends on the order in which the groups or components are selected. Activate the Trim tool from the tool palette (Mac OS X), the Solid Tools toolbar (Microsoft Windows) or the Tools > Solid Tools menu.

To perform a trim:
- Select the Trim tool (). The cursor changes to an arrow with a circle and a slash () if you are not over a group or component or a arrow with the number 1 () if you are over a group or component.
- Move the cursor over one of the groups or components. The cursor changes to an arrow with the number 1 ().
- Click on the group or component. The first group or component is selected. The following image shows the right group selected:
- Click on the second group or component. The resulting trimmed geometry remains.
Selecting the left group first would yield the following result:
Performing a trim by preselecting groups or components
You can also preselect the groups or components before performing a trim. To preselect groups and components and perform a trim:
- Select the Select tool (). The cursor changes to an arrow.
- Select two overlapping groups or components. The selected entities are highlighted in blue.
- Context-Click on one groups or components. The context-menu appears.
- Select Solid Tools > Trim. The two groups or components remain with the difference of the second merged. The following image shows the result when the left group was selected first:
Selecting the right group first would yield the following result:
