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.
In reply to oldmouldy:
Thank you. All of the parts I have created have the package boundry defined and the Max Height property attached. What I don't know how to do is to set up the .brd file to have areas where I specify the maximum allowable height of a component for that area. For instance, I have an area where the component height can't be more than 200 mils. I have components in my design that are up to 620 mils in height. I'm looking for how to have accidentally placed components that exceed 200 mils in the restricted area trigger a DRC error. Is that possible? It would seem so if we are putting Max Height properties into the footprints.+

I have done this, but I am always getting DRC errors for PACKAGE_HEIGHT_MIN even though I have not set a property in the keepout region for this.
In reply to mvonahnen:
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.
Hello..I am new user of PCB EDITOR. I have dificulte to create a circular package boundary (example: electrolthic capacitor).
Can you help me? There is any video or information about this!?
In reply to pmedronho:
Shape - Circular, set the class/subclass to Package Geometry/Place_Bound_Top (in the fold out Options menu on the right hand side of the screen) and then draw the circle you want. If your using 16.6 look at the Options menu and you can set the size you require and then Place Circle option and it will be attached to your mouse ready to place.
Dear BuddSW ,
This may not be the correct procedure but its simple way I follow when I have a height restriction in some area during placement . Draw package keepout in the area where you have a height restriction & assign the height limit for that shape( say 100mils) , when you view this in 3D veiw you will notice if any part placed which height is more than 100mil will protrude out as shown in image, but the issue here is you get CC error for all part placed inside that keepout
