Arc for polygon

[silvio3105]

Hi,

I'm trying to create tCream with polygons. It's for SMD standoff footprint. Recommended stencile cutout is below.

I cannot create it because Miter command does not support both radius types. Image is below.

Hi @silvio3105,

I hope you're doing well. You could achieve the desired tStop opening using the polygon command with semi-circular bends. You have to calculate the 4 vertices of one of the slices and then make 3 rotated copies. See the attached image.

Let me know if there's anything else I can do for you.

Best Regards,

Thanks for image, but I need to create 1/4 of circle(see image from standoff datasheet in first post).
And I need tCream for stencile. So I've placed PTH but it does not generate stencile for it.

That could be another feature request - tCream for PTH.
Also, I can create DXF in AutoCAD and import it in Fusion. Reason why I opened this topic is to point that some features are missing - like in this case "negative" radius.

Hi @silvio3105,

The circle image is just to give an idea of how you can make curved polygons since that would help you get the shape. I agree that we are missing drawing features.

Plated through holes don't generally get a stencil because the drill wicks the solder paste down into a hole.

Let me know if there's anything else I can do for you.

I hope you wrote that info about drawning features 😛
