-1 Dimension Needed

[MattK4VWA]

Hey Inventor Team,

I am currently fixing a drawing made by one of my colleagues, and i have run into something strange.

see attached screenshot (Sorry i had to cross out the names of my files due to workplace).

the Drawing is requiring -1 Dimension Needed, usually an error of over constrained will occur, but i have never seen this before.

Just wondering if anyone else has run into this issue?

thanks team

Hi

Please attach your file with sketch?

Hi! This usually means the sketch is corrupted or at least some parameters are corrupted. Try deleting the driven dimensions and see if the DOF hint becomes normal again. Or copy the sketch can paste it to a new sketch. Please share the file here. The forum experts can help take a look.

Many thanks!

Thank you, 
I deleted all the previous driven dimensions and this fixed it.

I believe the sketch was corrupted as there were also a lot of overlapping arcs, which once deleted and redefined fixed this.
