Selecting the Level at Which to Operate: <Model> <Category> <Entity>

The PROPS box operates at two levels: the top one applies to the whole model, and all its constituent categories; the lower one applies to individual items in a category. In this example the user has chosen to operate on individual parts.

Selecting PART at the top level...

...results in the PART s sub-panel being displayed.

It is also possible to SELECT any permutations of items, using the standard D3PLOT selection process or by clicking on their id button. Selected items have their background changed to green (here parts 1, 3 and 4 have been selected).

Operations applied to the top row buttons are then applied to all selected items.
