I’m learning with Allegro PCB Designer tutorial. Creating a Shape for the VCC Power Layer, isn’t working as stated. Prior to the operation the DRC flag is Green. Yet, as soon as I complete the following operation the DRC flag turns to Red.
· In mode Etch Edit, no selection
· Shape > Polygon
· Set Active Class ETCH and Subclass VCC
· Set Shape Fill type to Dynamic Copper.
· Browse and select VCC as the assigned NET
· Use mouse to create the polygon on the board
· RMB Done
· Tools > Update DRC
A very straightforward Operation. Yet, as soon as I Update DRC the DRC flag turns to Red. If I run Tools > Quick Reports > Design Rules Check (DRC) Report I get a blank report stating Total DRC errors zero 0. If I run Tools > Quick Reports > Design Rules Net Shorts Check (DRC) Report. I also get a blank report stating Total DRC errors zero 0. If I delete the newly created shape, and re-run Tools > Update DRC the flag return back to Green. I also tried to create that shape on an empty are with no packaged, same result.
Can anyone help me understand what is going on ?
What could be the cause for that strange DRC flag yet no reported DRC error ?
Thanks for your help
