Changed Items

In merging plates the interface tries to keep the original vertices as they may have been used for locating dimensions on drawings: it may be that just the positions have been changed. However, the comparison only works in list order: the interface does not look around for another vertex in the same physical place, although it may be in a different list position. Extra unwanted vertices are deleted on merging and all new vertices are added to the end of the list. A totally new Plate is just imported directly.

Note:
Changed objects are indicated as such by a change in colour.
