How ToMake A Custom Pastemask Shape ?

I would like to make a footprint of this IC.

I got the shape of the thermal pad done , but as shown in the attached picture , the paste mask is not equally shaped like the thermal pad.

How does one create the suggested paste mask so it matches the shape of the thermal pad ?

I tried to create a flash , but the problem is that i can not see where i need to place the segments of the paste mask .

Do i need to create the footprint of the IC and then add the paste mask in PCB designer to the footprint instead of doing it in the PAD EDITOR ?

Copying the thermal pad outline to the paste mask layer won't do . if you look at the past mask in the attached picture , you can see it is broken up in segments.

As mentioned above create the ssm file from the dxf import below:

How I do this type of paste mask - create the shape in an MCAD tool such as AutoCad or Solid works export to dxf and import the shape into Allegro.

Multple shapes added on the package paste mask layer in the footprint.

Just like this? Yellow is shape on PASTEMASK_TOP, Green is shape on SOLDERMASK_TOP. I use skill code to generate it.

That is one way to do it , i guess.

i have no idea how Skill codes work , nor have i ever used any. As i said i am fairly new to ORCAD.
