Draw -> Attach Hole

The Draw -> Attach Hole command in the Model module creates holes in a face. Holes can be created from closed curves. Faces with holes can also be extruded and revolved.

When attaching a hole, the following rules and tips apply:

The curve which represents the hole must be inside the face. The hole cannot partially intersect the surface or be located outside the surface. If you attempt to do so, messages advise you of this error.
For this operation, do not mix NURBS curves with others (Linear, Bezier, B-Spline, Cardinal).

Procedure

1. Select the face to which you want to attach one or more holes.

2. Draw one or more curves you want to define as holes in the face and close each one.

3. Position the hole curves in relation to the face, making sure that:

The hole(s) does not intersect the face boundaries, as described in the previous introduction.
The hole(s) is in the same plane.
4. Select the face.
5. Choose the Draw -> Attach Hole command.
6. In sequence, pick all curves to be the holes.

The face and attached holes remain highlighted as more holes are added on the face. If you subsequently choose the Info -> Selection command for the face, its related dialogue box indicates that it has holes.

After the Attach operation, the original curve is preserved and remains in the same spot as the newly attached hole. This superimposition may cause confusion later when you try to delete or detach the hole in the face. You may unknowingly select the original curve instead of the hole.

To avoid this problem, you should move or delete the original curve (use the Schematic window to select it) before performing operations on the face.
