Hi!
I've been working with Altium for a while now, and It's just amazing (especially after working with Eagle)! However I've stumbled across an error I can't solve
I'm working on a four layer PCB. the top and bottom layer is ground planes, and "layer 2" is 24V. This leaves layer 3 for the signal layer. The following screenshot is the output stage of a class D amplifier. On the top layer there's a poly cap together with an inductor. To make sure the polycap has a proper ground connection, I've added three vias close to the ground pad. (Note the "light" purple polygon on the pics are the internal 24V plane)
As you can see theres a little white circle and two lines on one of the vias. After running the DRC I get the following error:
[Un-Routed Net Constraint Violation] Un-Routed Net Constraint: Net GND Between Pad C603-2(3778.11mil,1740mil) on Top Layer And Via (3860mil,1790mil) from Top Layer to Bottom Layer
Why do I get this? The via is just connecting the top and the bottom layer, and has nothing to do with the cap C603. What's even stranger is that if I move the via away, I get an error from one of the other vias. See pic below.
What's causing this, and how can I fix this? I'm running Altium Designer 17.0.11.
