Crashing whenever I push pull a face

Anonymous — Wed, 20 Sep 2017 01:12:45 GMT

I crash when I try to push pull a face in Fusion.

Note: This was not an issue before I imported a logo as an SVG file and used split face to get it onto a curve. Now as soon as I use push pull or extrude the screen freezes and fusion does not respond.

Hi @Anonymous,

Welcome to the Fusion 360 community!

I am sorry to hear about the issue. It sounds like the issue occurs in a specific file, is that correct? Would you be able to share a public link to the design with me so that I can test? Also, a screenshot of the face you are trying to extrude would be helpful.

I look forward to hearing from you.

Here is a public link: http://a360.co/2xfGWnA

The face I am trying to extrude is the logo on top of the ring.

Thanks for any help.

Thank you for sharing the file! I tested and confirmed Fusion hangs as soon as I select a face in Press Pull dialogue box. I have reported the issue to the development for further investigation (the ticket ID is FUS-35368 for your reference) and I will share more information with you as soon as I hear back from them.

I apologize for the inconvenience.

Hello, I took a look at your model and I have some suggestions. First of all, you could greatly speed up your split face operations if you did them in a different order. Your first split face should be the outer loop of your sketch. this will divide the cylinder into three faces A (the original), B & C (the new faces with the outline of your sketch). Now do the next largest inner loop, then the smaller loops. Doing the outer loop first gives you two independent faces upon which later splits can operate, they are working on two simpler faces instead of one increasingly complicated face.

The main problem however is the fillets on your cylinder. When doing a press/pull we need to temporarily suppress any fillets, and perhaps due to the large number of edges on the part, this becomes very slow. An incident has been logged and we will investigate it, but I can suggest a workaround for now.

Delete your split features, then click on the leftmost arrow on your timeline to move the timeline back to the very beginning. Now advance one step so you see the base cylinder. Now carefully select the outer and inner fillet faces and press the Delete key. If done properly you will get a simple ring with four faces. Now do you face splits as I suggested above. Now do your press/pull to create the emboss. Once you are satisfied with the result, you can Delete the 'remove face' features to restore the fillets. You can then advance your timeline to the end again. Hopefully this will get the result you want and the model performance will be better.
