whats wrong with this geometry part 2 260318.3dm (73.6 KB)
I can see myself that the geometry is much too complex. It was just lines and arcs from the beginning, but then the original geometry was lost and dupedge created this mess.
Well, try running FitCrv on the curves in this new 3DM file.
FitCrv with tolerance of 1 mm. Something weird happens as you can see in the image above.

Hi erik,
I’m not clear from what you’ve posted what your design intent is in the detail so this is a general answer. Adapt it to suit!
Start by using _rebuild on the individual curves to something between 4 and 7 control points and degree 3, putting the new curves on a new layer. Draw in the straight lines. Then move the control points individually to get the shapes you want. Use _SetPt to line control points up where desirable.
If you want to get all the way back to simple elliptical arcs you can use _BoundingBox to put a rectangle around each of your curves, delete your curves and use the rectangle to guide arc placement (maybe tweaking the rectangles first).

Thanks.
Great help.
Will do further on.
But never forget to save the original curves …. somewhere deep down the file.

Hi @erik6
Jeremy gave you excellent advice. It looks like your original surface may have problems since I see a lot of overlapping curves that don’t line up or need trimming in your posted example file. In the future if you build your curves like Jeremy illustrates you shouldn’t have too many problems and as you mentioned always keep copies of your curves. I always put the curves on separate layers like moldingConst-Crvs and then surfs on moldingSrfs. Each color coded to help with visual analysis.
