Cant loft edges
Hi all of you, thank you for supporting people. I scanned my car mirror and wanted to rev. engineering to see if i can do it.
Firstly, I splited the mirror mash in many parts. Then i created many scetches and tried lofted them, starting from middle to left side (before that it was the right and it was nightmare).
It goes not bad untill the last curves. The last one which is D shape, whatever i did i could not make it one surface piece.
İ am sure there is easy way but i tried many things and stopped now.
I need to give thickness, 2.8 mm.
I am tired of tring now. What to do, what way i should follow the last area.
When you open it and try loft you will understand where i went crazy :(

Any tip🤔
Your curves are way too complex for this shape. The real surfaces would have been modeled with two main surfaces that are maybe degree 3 x 3, and then a blend of some sort between the two. You have zillions of points on your section curves and the curvature graphs are very spiky/wobbly.
I would recommend reviewing the Alias Golden Rules. While this is written for Alias users, the fundamental math and approach is the same in any NURBs based workflow.

I would also recommend this video from Onshape's own @GregBrown:
There's a lot more good surfacing and modeling info on his channel.
