About Trimming Round Geometry
You can trim round geometry (pieces) to achieve the preferred rounds for your model. As you create a round, the round geometry automatically propagates across tangent points and then stops at a non-tangent point. If you need to terminate the round geometry before the non-tangent point, you can trim the round piece up to a patch that you select. The following table illustrates the trim process.
 
You can only trim open round sets. If you want to work with a closed-loop round set, you must first use open the round geometry.
You cannot trim separate (overlapping) round pieces. To remove one of these pieces, hold down the CTRL key and select the piece, or clear it from its respective collector.
If you need to terminate round geometry at a different point other than a patch, you must define a Stop at Reference transition.
Trimming Round Geometry
The round placement edge reference is selected and the round geometry propagates across tangent points due to the existing round geometry (a).
The round piece is selected from the Pieces tab and the trim/extend handles appear (b). As the left handle is dragged to trim the round piece, potential extension geometry appears. Notice that the cursor and handle change during trimming.
Using the preview geometry as a guide, the handle is dragged to trim up the third patch (c). Notice that the preview geometry outline changes color indicating the extent of the trim.
Release the mouse button and the round is trimmed up to the patch (d).
