Sounds simple, but it just does not work. Maybe some switch has to be turned on for that or anything else? It is amazingly non-intuitive!
There is some polygon on TOP layer for the Etch class. I select it, menu pops up where I can assign color to it etc, again..means its selected, and nothing else is. I press Ctrl+D, or Select Delete from Edit menu, in the bottom it says something like:
Selected item not valid for current operation, ignored: Net "N05231"
No valid items selected for the current operation, exiting.
BUt how come not valid? I just want to delete it, I tried several modes, Etch edit mode, general edit modes and others, same thing!
...I'v used several PCB design software packages already, its the first time I come up with such a thing in Allegro.. any idea what am I missing? (maybe I turned something on/off and for some reason it just ignores my request to delete object? I have no idea..)
