I have te following problem. I have 2 airplane wings ribs. about 30 cm spaced from eachother. I want to cover them with a "skin"so I can use the contour command to extract more ribs.
But using sweep 2 rails where the 2 rails are curves from one rib to the other rib , and the ribs self are the corss sections. The "skin"comes out very distorted.
this is going to be a bit work, you may have to redraw everything. what you delivered here are polylines which generally are not very suitable for such kind of sweeps. and having kinks like shown in the image below will also not contribute anything positive in making a clean sweep.
as you see the 2 yellow dots indicate the horns on one profile.
what you can do is explode all then use the command CurveThroughPolyline on the rounded parts, and just simple lines on the straight parts then join them together. see that you keep the same amount of points on the rounded parts then sweep 2 will deliver you a precise transition.
just see that the round parts a joined before you use CurveThroughPolyline otherwise you will create new segments. also it might be better if you would have the rails on the leading edge and on the trailing edge for sweep 2, just in case it still does not work out.
@ RichardZ: thanks for you explanation , I do understand now why it doesn’t work. I tried to do it your way , and it was much better, but still a lot of distortion. Than I did the same, but in 3 parts, Top, Bottom and leading edge. Now I can’t see a distortion.
