Possible bug with the Extrude tool?

[Anonymous]

Hi!

I've been using fusion360 for some time now, and its been great. However I have run in to this issue that appears to be independent of the file I first found it in. I've taken some screenshots below to describe the problem, but the general issue is that fusion seems to let me select the features I want to extrude, but after I hit "ok" it only extrudes a portion of them. Really not certain what is going on here, any help/suggestions would be appreciated.

EDIT 1: I should say that I can extrude the features that didn't get extruded in a second extrude operation, but I can't seem to get all the features to extrude in one operation.

EDIT 2: It seems to be that fusion is de-selecting some of the sketch regions selected in the extrude operation. When you double click on the erroring extrude in the timeline to edit it, it shows that the only selected regions are the ones that it did extrude, not the ones that were originally selected.

Sketch before extrude:

In the extrude dialog selecting regions to extrude on said sketch:

After hitting "ok" in the extrude dialog:

@Anonymous,

We have seen some cases like this in the past, and are very interested in fixing them.  Would you be willing to share this model with me, so we can investigate?

Thanks,

Jeff

Yes definitely. How do I do so?

Choose one of the methods described here:  share a fusion design.  They all work pretty well, IMO

Ah yes sorry, here are two files that both exhibited the same issues. Unfortunately I've done workarounds on both models to get them to a finished state, but the extrude in question is Extrude2 for both models. As I said before, these are 2 separate models (i.e. V2 is not a copy of V1).

Thank you, @Anonymous, that is easily reproducible.  We will look into it, and appreciate you sharing the model with us.

I am a developer working with Jeff. We looked into the attached model and verified the issue has been fixed. The extrude will be constructed correctly in the next release update.

Meanwhile, if you need, there is a way to bypass the issue in the current release product. Just trim out small common segments between the inner loop and small rectangular faces, then you can select the profile as one face for extrude.
