About Merging Segments
You can merge two or more distinct pieces of unattached segments to form one segment. When merging segments, keep in mind the following points:
Geometry from a first segment can only be a base segment.
The segments must be tangent to one another.
The driving and offset sides of the segments to merge are swapped automatically, if necessary, to match the sides of the earliest segment created.
Swapping the driving and offset sides can change the location of cuts located on the segments. For example, when you reorder a Merge feature in the Model Tree and reinsert it before a cut that references an automatically swapped side, the location and the geometry of the removed material may change.
Icons in the lower right of the screen indicate whether a part has one or more distinct pieces of unattached segment geometry.
You can also merge segments automatically during segment creation by clicking the Merge to model check box on the Options tab.
This option is available for Planar, Extrude, Revolve, Sweep, Offset, and Swept Blend segment tools.
Unattached Tangent Segments
Merged Segment
1. Unattached segment.
2. Base segment to which the unattached segment is merged.
When you merge segments, you must define the following elements:
Basic Refs—Select surfaces of the base segment.
Merge Geoms—Select surfaces of one or more unattached flat segments to merge with the base segment.
Merge Edges—(optional) Add or remove edges deleted by the merge.
Keep Lines—(optional) Control the visibility of merged edges on surface joints.
