I'm modeling a shield and got stuck with a problem. I want to fill the whole back of the shield mesh, but can't figure out a solution on doing so. I can't just press F to fill since all of them are individually modeled, but all of the vertices are aligned. I've attached a screenshot bellow
Hoo boy. Ok so before I suggest something to solve this at this stage, id like to really reconsider your workflow in modeling: Fill first, extrude later. Also: do not intersect geometry (non-manifold meshes)
For this case i would say that maybe if you used the "Grid Fill" feature you could fill the faces to make sense on automatic (space -> search: "grid fill"). Otherwise theres always the soul-crushing way of doing it by hand: quad by quad (have fun)
At this stage id just trash what you did here, and restart the whole model with the elements already filled and then extrude them. It doesnt look like too much work.
The process to make this work with F (Fill with NGons) or Alt-F (Fill with Tris but this can "detect" holes) will be quite tedious.
I would say remove the extrusion loop and work your way to make it manifold. The fill an then extrude.
Or maybe start from scratch and use your current design as template to trace a new modell the right way.
