Thanks Andrew,
Is this the only way?
Seems a little strange to be adding layers.
Is there a back door to the existing sub class Pin - Pastemask_Top?

Ed,
You would need to create a new subclass within the symbol, say, in
Package_Geometry/Paste_Top, and put the geometry there.
It will come into your design when the symbol is placed. The catch is, you
need to add this subclass to your artwork control manually. If you don't
put it there, it won't be output.

Gerry,
How do I add a solder paste pad to a symbol independent of the padstack
editor?
Thanks,

Ed,
You can just add the shape to the symbol on etch > top. When you import
the part into you're board file assign the shape to whatever net you want
and drop in some vias. You can include the soldrmask and pastemask in the
symbol.
This does not require a ninth pin to be added to the logic symbol.

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.
Hope this helps

Hello,
very unfriendly from you, not to tell HOW did you figure it out.
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.

Bye

[PCB_FORUM] Heatsink Pad
How do I generate a polygon Heatsink solderpaste pad? 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
