DRC Driven Same Net Spacing Clearance Working for Through Pins but Not SMD Pins

l3hrbonini

As stated in the title, DRC driven clearance appears not to work for SMD pins, but does work for through-pins.  I can add properties for clearance and type to the SMD pin and that will work just fine, but relying on the constraint and global parameters just results in a full contact connect.  I've looked through global parameters and constraint manager and everything looks correct to me, and is the same for both through and SMD pins.  Is there somewhere else I should be looking?

    Is this for a Dynamic Shape? If so look at Shape - Global Dynamic Params - Thermal Relief Connects and see what is set there. Also make sure on Void Controls tab the values are set to DRC which then follow the Constraint Manager rules. If this isn't it maybe a few screenshots to explain what's not working.
