I am trying to fill in the the region between the two projected curves. I have attached the file.
Im just not sure what to exactly do.
I'm getting the following error when trying to open your part. Can you post some screen shots and maybe those could be use to guide you?
I tried to do this with boundary surfaces and couldn't do it. I finally just converted the back of the frame to a sketch and extruded it.
You need to add some curves to connect the project curves.
