Hi guys, What am I missing here? I haven't had to create an area that allows a limited package height for a while, and it's not working as I expect. I have a Package Keepout/Bottom circular shape that I want to disallow parts that are taller than 50 mils. I put the property "Package_Height_Max = 50 mil" on the shape, but a part with a Package Height of 37.4 mils still get a DRC error: [cid:image005.jpg@01CEC661.33C48E90] [cid:image006.jpg@01CEC661.33C48E90] Anyone know what I'm missing here (i.e. doing wrong)? Thanks for any help. Regards, Gary MacIndoe Senior PCB Design Engineer EbD R&D Hardware Surgical Solutions Group Covidien Boulder, CO
