About Extending Round Geometry
You can extend 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 continue the round geometry, you can extend the round piece up to a patch that you select. The following table illustrates the extend process.
You can only extend open round sets. If you want to work with a closed-loop round set, you must first use open the round geometry.
You cannot extend 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 extend round geometry at a different point other than a patch, you must define a Stop at Reference transition.
An automatic blend is used to fill the gap around a corner. This blend cannot be modified or deleted. If a blend cannot be added, extend cannot be performed.
Extending Round Geometry
The round placement edge reference is selected and the round geometry stops at non-tangent points (a).
The round piece is selected from the Pieces tab and the trim/extend handles appear (b). As the right handle is dragged to extend the round piece, potential extension geometry appears. Notice that blend transitions are automatically added where a gap exists between tangent points. Also notice that the cursor and handle change during extending.
Using the potential extension geometry as a guide, the handle is dragged to extend the round piece up to the third patch (c). Notice that the potential extension geometry outline changes color indicating the extent of the extension.
Release the mouse button and the round piece is extended up to the patch (d).
