PCB Export: Cylindrical Holes vs holes with a lot of faces

gmdouglas — Thu, 21 May 2020 17:21:01 GMT

HI all. I've exported a PCB from Eagle 9.6.1 to Fusion, and there's some inconsistent behavior with PCB holes in the Fusion body.

Even with copies of the same component/footprint, sometimes the holes for the component are normal, cylindrical holes, but sometimes they're structures composed of a lot of flat faces.

Why might this be happening? It makes joints referencing the center of some holes VERY difficult.

What can I do to prevent the face-type hole -- or what might I have done to make it happen for some and not others?

The attached screenshot shows 2 holes, both from the same Eagle footprint ( 2 of the same components side by side). I see this behavior with a number of components where some are normal holes and some are not.

Thanks for your help.

Hi @gmdouglas,

I hope you're doing well. I've pinged the developers on this.

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

Best Regards,

Thanks Jorge. Let me know if the developers need to see the project.

Hi @gmdouglas,

I hope you're doing well. The devs got back to me, it turns out this is a complex issue that occurs whenever fusion merges copper objects. They've made a few improvements but there's still more to do.
For now there is no workaround.

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

Best Regards,

Hi,

sorry to dig out this old thread, but are there any news on this? I just stumbled upon this problem today and I hoped it got solved after 5 years.

Thanks and best regards,

Aleksander

Hi @a_lubniewski ,

I hope you're doing well. As far as I know this hasn't changed @HelenChen-Autodesk could you investigate the above issue?

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

Hi @jorge_garcia , @a_lubniewski ,

Based on my understanding that there is no such issue in Fusion Electronics if we push the 2D PCB to 3D PCB directly in Fusion.

For the Fusion sync from EAGLE to Fusion, there is some limitation unfortunately.

So may we suggest to use Fusion Electronics instead to get the expected 3D PCB board file instead?

Hope it's OK for you.

Much appreciated for your understanding.

Hope you have a great day.

Best regards,

Helen
