Regrouping

There are two functions that perform reorganization of the subpicture structure in a drawing, REGROUP and SPLIT. SPLIT should be used when parts of the information in a subpicture should be moved to a new subpicture, with the same subpicture properties (for example, attributes, color, layer, ). REGROUP should be used when some information from one subpicture shall be moved to another one. A level 1 subpicture will be created if OPERATION COMPLETE on the menu is selected instead of an existing subpicture in the drawing. The information to be moved can be selected in a number of ways. In an already well-structured drawing, the most frequent ways to select information will probably be by using the activities subordinate (subpictures on next lower level), neighbors (subpictures on the same level, only when REGROUPing) and by picking geometry. In non-structured drawings, on the other hand, information is probably selected most efficiently by capturing all data inside a polygon or an area.

Note: The capturing process is always a lot quicker if the user captures information that is completely inside a polygon or an area. This is done by selecting the "NOCUT" alternative in the submenu of the SPLIT > REGROUP function.
The user must be aware that subpictures with the model information should normally not be reorganized. This could result in the fact that the hidden line process fails, that model information can not be fetched to the drawing.
