We have made improvements to the way a surface is rebuilt when changing the U or V Degree or Spans in the Control Panel.

This functionality is also available from the Surface Edit > Rebuild Surface tool when setting the Rebuild Type to Rebuild.

• Previously the surface was rebuilt in both the U and V directions even when only a U or V setting was modified. This could cause changes in an edge that you did not intend to modify. Now, changing the U degree or number of spans will not affect edges running in the V direction and vice-versa.

  

• Previously, the surface was rebuilt with a uniform distribution of spans, regardless of the original distribution. This could cause unwanted modifications in multi-span surfaces. Now we maintain the original distribution of spans while creating additional ones as needed.
