Loop cut at an angle I need to add an edge to a model at an angle without distorting the overall shape.



I can add a loop cut and rotate, but this skews the model



I'd like to keep the lines consistent, so I don't want to deal with scaling after rotating. I'd assume there is an easier way to do that, but maybe not.

Thanks,
Instead of doing a loop cut you can use the Knife tool. 


Press K to start the knife tool.
Optional step: If you need to cut 'through' the mesh (so the cut goes all the way around) press Z to toggle the Cut through option on.
Click once above the mesh and once below to create a cut across the mesh:





Press Enter to confirm the cut.
