Failed to Solve - Bug?

I have a fairly simple project and I've tried this in several new projects today and had the same result but on different measurements. I add a measurement then change it and it suddenly stops computing. I have no idea why it's failing as these measurements are totally valid -- I have made sure by copying the entire sketch to a new file and applying the measurements and it immediately computes the whole sketch properly. I have had to start new files three times already today for this reason. I've cleared the cache and restarted both the app and the machine several times.

I would appreciate any help. After years of using F360, I've never before encountered this but it has been plaguing me for hours today in several projects and I'm wondering if it's a new bug or an old one I've just never hit before. I'm using it on a fairly new Macbook Pro, M1 processor, fully-updated.

 

I've attached screenshots of what I'm seeing. These dimensions are completely independent of the rest of the sketch -- they're literally drawer handles and the only constraint on them is that they're symmetrical and equal to each other but those dimensions could range a long way in either direction and should compute perfectly. I've done so many complex models but this is literally a few rectangles and it's failing every time.

Simple Project - but complicated sketch, made worse by the sketch mirror command.

As sketches have no history (other than Undo in a live session) any debugging will fall back to you.

Hi,

Please share the file.

 

File > export > save as f3d on local drive  > attach it to the next post.

I would model very differently.

1. I would model with symmetry about the Origin.

2. I would not duplicate sketch elements.  (I see a lot of duplication in Sketch1 - each geometry constraint that Fusion has to solve gets more computationally expensive as duplication increases.)

3. Components (and their instances) would duplicate the real world twin.

4. I do not see real world clearances for any "drawers" to move?

 

I can think of several different strategies than the file that I attached - but any strategy would have one thing in common - very simple sketches.

Use single lines and Extrude Thin Feature for planar sheets.
