Error when mirroring surface

[jeffreyVR4JW]

Hi!!

I have been learning how to surface model through youtube for the past few weeks. I have started on my first project, which is making my head. The only problem is that, when I try to mirror my stitched surface, it gives me an error. I know it has something to do with sketch 2 of my project, but i just don't know why. (Know this because this where the i with blue circle icons show up next to my sweeps. lofts, etc. Any help/ guidance will be greatly appreciated

Thanks!!

Hi @jeffreyVR4JW .

The sketch 9 is the problem. It contains a lot of indefined geometry (Magenta). If you don't want to delete them, select them all and delete theire constraints as indicated in the image below. I attached the model with mirror created without any problem.
