No, I haven't tried canvas. I am quite new to the world of EDA suites.
Sometimes I noticed, the program allows me to place tracks and vias even if something else is inside the clearance area.
Is this alright because the program allows it, or will I be facing problems down the road? If it's alright, then what is the point of showing clearance anyway?
Edit: Just tried canvas. It looks pretty, although I'm not quite sure what I'm seeing.
