Heal Edges PropertyManager
You can merge multiple edges into a single edge. This is useful on imported
parts, where edges sometimes import as multiple short edges.
To heal edges:
Click Heal Edges
(Features toolbar) or Insert,
Face, Heal
Edges.
In the PropertyManager, under Faces:
Select the faces whose edges you want to heal
for Face(s) to Heal 
.
Set Angular
Tolerance to the maximum angle between the edges to be merged.
Set Edge
Length Tolerance to the maximum length of edges to be merged.
Example:
If you set Angular Tolerance to
2deg and
Edge Length Tolerance to 5mm,
then edges with angles less than 2° at the vertex between the edges, and
length less than 5 millimeters, merge into one edge.
Click Heal
Edges.
Under Edge Information, Before and After
display the number of edges in the part before and after the Heal
Edges operation.
