Group the selected entities into a single block. This is an advanced option that should only be used by experienced users.
At times you may need to erase or build individual surfaces, then group them together to form a single block. This function groups entities together to form seamless closed block from individual surfaces. Note that when using this operation the user must ensure that the grouped surfaces form a seamless, closed surface envelope with no internal surfaces. The presence of internal surfaces may cause errors.
The group function was implemented to allow advanced users to erase a few surface elements and rebuild them. It is also useful for joining surfaces together that are brought in from CAD packages. Note that the user is required to ensure that there are no internal surfaces and the surfaces you group together do form a seamless, closed surface envelope.
