Creating Web/Thermal shape for paste mask

You could create four static shapes on the package geometry / paste top layer in the footprint.

You could also create a shape symbol and add it to the pad stack.

That is the way I have been approaching it, but was looking to see if Cadence had a skill file that would take od, id, w and angle and create one. I could not find anything and so I created a python script that does the math and generates a pcb script that can be replayed in allegro. Works great, I provide the four parameters, run it, and it generates the script that I replay and create the shape as seen below.

Hi JS,

Nice work !. Might I ask did you come up with a method to fill the shapes and what was the key method needed to create the shape geometry within the PCB Editor so as to get your wagon wheel type shape.

Best Regards

For each segment, I used poly line shape that has two lines and connected the end points with arcs. I used geometry to figure out end points, connected with arc, two end points and middle. 

I am away from my computer this week but I can post my python script on GitHub coming weekend. Python works great for matrix operations to apply rotations and reduces the amount of code a lot when using numpy.

Though, what Hoangkhoi just posted is much simpler and I really like that.
