I have a file with a component and i have kept the component's single sketch intact. When i have finished the design it will be cut out on a cnc router and then folded.
My impression is that i could possibly tackle this project two ways, i could design it in final form, and then do a flat pattern for the cnc router. Or i could design it as a flat plate, and then fold it. I decided to experiment with the latter approach this time having used the former approach previously.
Naturally during the design process i need to fold the plate to see how it shapes up and then unfold it to modify the sketch, or at least i think so? This has been tedious and time consuming but i have been kinda happy enough. I had the premonition that i should make sure that i save it when it is unfolded to avoid issues. Unfortunately i wasn't paying attention and saved it while folded.
You would think that should be no drama, any decent program should be able to handle that, but when i reopened the file and unfolded the plate i found i was specifically disallowed to edit the sketch. Oh dear, thats no good. I decided to get rid of the design history, and great, i was now able to edit the sketch. So i invested a fair bit more time refining the design, then tried to refold it. However, to do that i need to convert it to sheetmetal, and when i try to do that it is now specifically adamant that i can only select part of the component, a sector as defined by lines on the sketch.
It seems that no matter which way i try to design sheetmetal components in fusion i end up having to devise workarounds, or is there a solution?
