Deleting Holes In Surfaces

Problem

Surfacing techniques help modify parts, especially when the part is imported and has no feature tree. One such modification is removing holes from an imported part. The following examples assume that the imported part is a solid body with a hole through it. This article goes over how to use the "Delete Hole" feature to remove holes in surface bodies.

Solution

  1. Delete the inside face of the hole with "Delete Face" (Insert > Face > Delete)
  2. After deleting the inside face of the hole, the part should become a surface body, which can be confirmed by seeing the blue edge on the hole, which indicates an open surface
Open Edge example
  1. Select the edge of the hole and hit the "Delete" key on the keyboard
  2.  In the dialog box that comes up, select "Delete Holes"
Select Delete Hole
  1. The hole will be closed up and knit into a surface, and a "DeleteHole" feature will be added to the feature tree

This feature will work for any hole in the surface body, ranging from circular holes to irregular holes as shown below.
