About Recognizing Features from an Existing 3D Shape

In some cases, there may be an ambiguity regarding selection of faces for generating the walls. Such cases are discussed below.

For example, if the initial shape is a box, you must select two opposite inner faces, and two opposite outer faces on the other two sides of the box, to avoid overlapping when recognizing the walls.

Faces to select

If the faces are overlapping, you need to select the sides of each face. If you select only one face, the overlapping faces will be recognized as a unique pad and not as two independent walls.

To avoid this, you must first select the inner side of the overlapping faces, then select the outer side. The overlapping faces will be recognized as independent walls.
