Unable to edit sketch

[barry9UDQ6]

I am working on a design that I am not able to share, and all of a sudden have a new problem.

I made some serious changes to my skeleton model which has resulted in some downstream failures, mainly sketches that have jumped around.

On this particular piece I have dragged the history marker back to repair the sketch.

As an example, if I RMB on the 1st sketch I get the option to edit sketch:

But for the second sketch, no option:

At no stage have I switched the timeline off. I must say this has never happened to me before..

Notice it has the option to unsuppress, is that the reason you can't edit, it's suppress?

I wasn't able to find out, and I don't remember suppressing that sketch.

Trying to unsuppress  just locked my PC up. Ended up deleting and re-doing it.

Just did a quick test on a simple design and suppressing a sketch does give the menu you see above.

This is what I see with a sketch suppressed.

If you are curious about the suppressed sketch you could open an older version of the design and check. I don't recall Fusion suppressing a sketch even after making quite big changes.

the only situation where Fusion will suppress a sketch (or any feature) is if you suppressed something "upstream" that that sketch depends on for its sketch plane.  So, if you create an extrude, then sketch on a face of that extrude, then suppress that extrude, the sketch will become "indirectly suppressed".

Thanks Jeff, I think this is what happened.

Although what was confusing me is that I had dragged the history marker back, to in front of the upstream features.

So I was't expecting it to 'remember' the suppressed feature.
