"Edit 3D Extrusion Depth" Dialog

Using different extrusion depths within one surface, you can realize penetrations, sinkings, and raisings. Here are some examples:

Example 1: Both outlines have identical depths - hole

Example 2: Inner outline has a "lower" value 0 and an "upper" value > 1 - raising

Example 3: Inner outline has a "lower" > 0 and an "upper" value of 1 - sinking

Example 4: Inner outline has a "lower" value > 1 - hovering

Example 5: Inner outline has a "lower" value < 0 and an "upper" value > 1 - penetration
