Can't redefine sketch plane

[rmcooke22]

Hi Folks,

I've done something that has caused Fusion to give me the following error: "The sketch plane is lost, Cache is used. Please redefine the sketch to select other plane!"

When I try and redefine the plane the entire body disappears and there's nothing for me to click on.

 Anyone have any ideas what I did wrong and more importantly, how do I fix it?

Thanks in advance,

Richard

Hi @rmcooke22 , 

thanks for posting! this usually happens when The plane or face the sketch was created on has been deleted, repatterned, or recopied, breaking the reference. You can move the timeline marker before the sketch and create a construction plane. This plane can then be selected as the reference plane for the sketch!! Let me know if you have any questions on this 🙂

thanks,

Hi Julia,

I don't think your solution will work for me.  If I move the timeline marker to before the error there's nothing displayed. So I can't see where to put the new construction plane.

Thanks,

Richard

hi @rmcooke22 , 

I see what you mean!! I was able to drag the construction plane to before the sketch, and use that!! see my screencast here: https://knowledge.autodesk.com/community/screencast/168b3b84-90b1-459a-aa86-2652ec45ce1f

hopefully that works for you as well!

Hi Julia,

That worked like a champ.  Thank you so much.  I could never have come up with that sequence on my own.

Your advice, guidance was very helpful, i was about to delete and restart the whole project. Thanks.

Hi Julia, 

I have a similar issue. I have deleted a component that I was using as a sketch plane. After I deleted it, similarly there is an error message stating "The project source is lost, cache is used!" 

Normally I would click on the sketch with the error and 'Redefine Sketch Plane' but when I right click there is no option for this. I can't even make a new Plane to suit my sketch because the sketch itself can't be redefined without the option in the list.

Any help would be greatly appreciated!
