I want to create a bottom keepout area: -no bottom component placement - no vias -no bottom etch I've created a bottom keepout area: when I place a through hole e-cap on the top I don't get any DRC error. How can I get a DRC error when a through hole component is placed on the top? Thanks,
You need to put bottom side place bound shapes on your symbol pads. Give them the maximum protrusion of your pins (2mm?)
This sounds complicated. Is there a easier answer to my problem? I assumed Allegro to be smart and realize when a symbol has through hole components and give me a DRC error.
Defining PLACE_BOUND_TOP shapes in your package symbols is a standard part of good library development. Every through-hole part is also present on the second side of the PCB (where the leads protrude or are clinched perhaps). Therefore it is good library development practice to define PLACE_BOUND_BOTTOM shapes describing these areas where the leads are present. Incorporating this as part of your lib development process requires very little extra time and will address your immediate problem.
