2. MODELING

CHAPTER 2 "MODELLING" 53 We see that the sub-surfaces have been connected correctly. Some OBSERVATIONS about the process: - When we consolidate two or more groups, the program creates a new main group that includes all subgroups cumulatively, keeping the properties of each subgroup independent of the general properties of the original groups. If, for example, I consolidate two groups that one has a thickness of 40 cm and the other 50 cm, the subgroups will keep their thicknesses correct, regardless of the thickness I see in the new main group. - The command creates a new main group and new lines - outlines which are also placed on a new layer. All existing elements (original groups and original lines - outlines) still exist and if the user wants to the user can delete them manually after the consolidation. 4.2.1.3 Grid consolidation for contour correction The unification command can be applied to a master group AND to a master group and has the meaning of reordering i.e. correcting the outlines (double lines and breaks where they should be). Let's look at an example: We have the following two walls
