I created a couple of footprints with mechanical alignment holes that go through the PCB (I also created the padstack that defines the holes). As far as I can tell, everything looks fine for the various holes while in the footprint editing mode. When I bring the parts into PCB Editor to place the part, I can see a shape in the area where the holes should be, but none of the shapes are the right size and I'm able to route in the area without a DRC. When I switch to the 3D view, the hole shapes appear to be the right dimensions.
Any thoughts on what I need to do differently to get the holes to show up in PCB edit mode? Thanks in advance for any help.
It sounds like they are defined a mechancial holes without a pad. The color is defined under Display - Color Visibility Display folder, set something other than black as the color for drill holes. To get the DRC modes to work you need to enable it. Got to Setup - Constraints - Modes - Spacing Modes and make sure all the Hole to items are checked. Ideally everything in that list should have a tick. Then you should see the DRC's when routing. Make sure your drill hole size is set correctly in Pad Designer.
In reply to Ron Scott:
Ron and Steve,
Thank you both for the quick reply. In my case, going to Setup->Design Parameters and slecting "Display Non-Plated Holes" resolved the issue of not seeing the hole. Setup -> Constraints -> Modes gave me the view to turn on the DRCs.
Thanks again for the help!!
