warning: empty toolpath

Icon_Design — Thu, 20 Jan 2022 02:50:00 GMT

Hi, Its been several months since I've been in fusion 360. When I fired it up, there was a warning that a manual SW download was necessary because of a bug in the auto installer. So I went ahead and updated the code but then when I loaded my latest model, about 50% of the cutter paths are showing an error!!

But if I double click the WCS in the file tree, it opens up the dialog. When I go to the geometry tab, it still recalls the faces or curves that were selected for the path. But when I click OK, nothing...same error. Soooo frustrating!!!

help would be appreciated.

Can you share your file here?

What operating system do you have on your computer?

Hi Seth,

would rather not put this data into a community. I tried to email it to you but that bounced. Can you give me a good email address to send the data?

Okay, here's what I've found:

1) Clicking the OK button isn't enough to force a regeneration, nor is selecting the toolpath and pressing CTRL+G (which is odd, worthy of further investigation)

2) If we select all the toolpaths and Right Click > Compare and Edit, we can globally change the Tolerance on all the toolpaths. Changing it from .01mm to .012mm is all that is needed, click OK.

3) Toolpaths will now regenerate, showing valid toolpaths:

Hi Seth,

Thanks, it took care of "most" paths but not the drilling op's. The tolerances cannot be edited here (that I know of). Any idea how I can fix these? Also curious why the other paths required a tolerance change....seems a bit odd to me.

As it turns out, the path I sent you down was a red herring. I did not recognize that when I pressed CTRL+G, my keyboard input was not registered (issue on my end, not yours or Fusion's fault). The idea behind a subtle change like Tolerance was to force it into a state where it needed to regenerate, without changing anything complex.

I went back and tried it, and selecting all the operations and pressing CTRL+G did yield positive results, although there is some delay in processing

You can also select the operations and right click > Generate

oh man....that worked...For whatever reason, I did NOT think to do something SO obvious. I guess that I dismissed that in my mind since I could not get any single operation to work after going into editing mode.

thanks for all the great support!

9 times out of 10, opening a toolpath, changing nothing and hitting okay, will do....nothing. If the toolpath is invalid (red "!"), it should regenerate.
