Fix gaps between stitched edges and vertices to make the actual geometry of the
surfaces consistent with the model topology.
Navigate to the Geometry ribbon.
While in idle mode, select surfaces.
Right-click and select Edit > Optimize CAD.
In the dialog, enter a geometric tolerance value.
If a gap is found to be bigger than the specified tolerance, then the surface
and edge geometries will be morphed parametrically and in 3D, if necessary,
to make the gap smaller than the tolerance. In addition, non-essential
degenerate edges are removed.
Click OK.
The original geometric entity IDs are also preserved. The same functionality is used
for the Optimize for CAD option in the Geometry Export Options dialog.
Example: CAD Optimization
This example demonstrates the difference in results when using the Optimize CAD tool
to update geometry that has previously been repaired with topology-based geometry
cleanup operations, for example, toggle/equivalence/replace edges, replace points,
and so on. Figure 1. Unrepaired Geometry
The geometry below was repaired using only topology-based geometry cleanup
operations. After the geometry was meshed, you can see that some of the elements
have become distorted. After untoggling the edges, there is still a large gap in the
geometry.

Tool
Figure 3. Meshed Geometry
Figure 4. Geometry with Edges Untoggled
The geometry below was repaired using topology-based geometry cleanup operations and
then updated with the Optimize CAD tool. After the geometry was meshed, you can see
that there are no distorted elements. After untoggling the edges, there is not a gap
in the geometry.
