Hi Dale,
At first I was confused because I expected a mouse click to toggle the selection state
I found now however that deselecting is as with regular deselecting via CTRL+LMB.
For my purpose I need the possible objects to select to be limited, but I’ll see what I can come up on my own with after scrutinizing what the Custom.GetObject() has to offer.
Thanks for getting me up to speed!
