Sometimes surface edges do not match on a translated part. To stitch a body into a solid, the edges must match. Use Extend Face to lengthen or match surface edges.
Open a file that contains surfaces and enter the repair or construction environment.
On the ribbon, do one of the following:
Click Repair tabModify panel Extend Faces
Click Construction tabSurface panel Extend Faces
.
In the graphics window, click a surface edge to extend. At the selection point, a line extends to preview the distance the face extends.
Enter a distance in the dialog box.
Click Apply, and continue selecting edges to extend.
