Clipping plane obscured objects are selected when using Layer selection functions:
When selecting objects in the Layers Dialog, using for example “Select Objects” or “Select Sublayer Objects”, objects not visible due to clipping plane(s) being active are selected anyway. To me this behavior is not according to what would be expected. (Eg I’m working on the lower story of a building and want to select the materials on a specific material layer … when I do that with a clipping plane only showing the lower plane, materials on all other stories are selected as well. Contra-intuitive).
Partly obscured / clipped object should still be selected.
That’s actually consistent with most of the selection tools. AFAIK the only ones that don’t include obscured items are the lasso type and mouse clicks.
How this should behave can quickly get complicated. For example, if you want to move a group you probably don’t want an obscured component left behind. So even the lasso and mouse click will include the obscured members of a group.
But … having complex models with many different complex parts … one can use layers to handle the complexity. But it means having the same layers on each floor for example. So the layer “furniture” gets repeated on 10 different floor levels. It works, but requires a lot of housekeeping.
The behaviour you are describing is already built into the group features. Grouped objects not visible (or hidden) are copied (temporarily shown when the copy is made). With clipping planes the hidden objects are not shown at all. Giving the user no clue whatsoever is going on. I only noticed this because I knew I had 5 objects on one layer on the first floor, and then another 10 on the second floor, being clipped away …)
I think it should be optional, making different work methods possible. For me as an architect, it is very usable.
I understand this is tricky, but even for the most tricky problems, there are brilliant solutions.
