To Use the Push Deep Command
The Push Deep command removes all the triangles that match the point density of the selected triangles by propagating through the model until the point density changes. This command also removes the internal structures that have the same point density.
This command is similar to the Push Shallow command, but the depth of propagation is greater.
1. Select a set of triangles.
2. Click Wrap > Push Deep.
