Hello Michael,

thanks for the answer - and sharing your minds.
But one Thing I didn't understand - what is it caused by, that the Event for "click", can't select a custom command?
I understand the described catia - function like that:
The middle or a right click selects (maybe blind) an element or - if there is no hit -creates an intersection point with an invisible plane (depending of the Viewport alignment) and do an viewport reset.
Or is it in principle not possible to get click- and "mousebutton down Events alternatively?


Thanks in advance
and
have a nice day

Karsten

p.s: Maybe combinations of Buttons:-)
