Sorry - didn't mean to seem unfriendly First, I generated the unique pad shape with the Allegro editor... Start new enter a unique file name select drawing type - Shape symbol in the editor - go to Shape add polygon draw the shape save (Important - make sure the Setup Drawing Parameters is set to Type: Shape) Open padstack editor go to layers tab select each appropriate layer and change the geometry to shape (under Regular Pad) pick the nav button beside Shape and find the unique file name you assigned to the pad shape This still leaves a problem in my symbol. It has 8 pins and the heatsink adds a 9th pin. This means I have to add another pin to the schematic symbol in order to tie the heatsink to the appropriate same net pins.

It is nice that you found a solution, but it would be even nicer, if you just would tell something like this: ============================== never mind - figured it out by pushing on the third button from the left on the opening page.

The symbol editor accommodates copper and soldermask but no solderpaste. Is this done with a custom padstack? If so, how do I generate the polygon padshape so that I can import it into the padstack editor? Thanks, Ed Ed Caldwell Circuit Board Designer Voice: 770-622-8707 Email: mailto:ed.caldwell@xxxxxxxxxx
