Maximum Package Height

BuddSw
BuddSw over 14 years ago

I am using Allegro PCB Editor 16.3.  Although I have used this product for a while I've never needed to add Maximum Package Height as something to flag using DRC.  I've looked in the documentation and the only constraint-setting information I can find is for spacing/width/pairing type stuff.  Where can I find the documentation to set up maximum height constraints?  I know I can manually check each package on the board for it's Max Height property that is far from ideal.

 I will be grateful for any insight that can be given.

    OK, for a keepout, Package_Height_Min is going to be 0 if you don't specify a value, that's going to be the board surface, so any parts placed within the boundary of that shape will cause a DRC. You increase the Package_Height_Min property of a Package Keepout to raise it off the board surface to allow parts with a height of less than, or equal to, the Package_Height_Min to be placed there without a DRC, parts with Package_Height_Max of greater than the Package_Height_Min of the Keepout will generate a DRC.

    I know this is an old thread, but I felt the need to say THANK YOU. There are a lot of questions answered here and other forums at a level that is nigh impossible for a beginner to understand, but this one is golden. Short, simple, and clear, this is exactly what I needed.

    Edit: Added quote for clarity
