I try to sketch a wingtip for a RC acrobatic glider. The wingtip has its airfoil, this is a rough drawing: [image] The final body should be a nice bulb-like body like this: [image] The airfoil is not symmetric, the rotating tool seems not to be the best choice. How can I create such an object? …

@Robin You may find the magic of Tools > Loft useful?

[IMG_0759] This was a very quick attempt at showing a ‘bulbous’ shape at the wingtip. Using your ‘shape’ should give the desired effect. This is a ‘rough’ drawing :sunglasses: It may seem tricky getting the Loft to end smoothly, keep trying and you will win!

I tried the method but didn‘t succeed. The body of the example has some parallel surfaces and curves with defined measures. My body has nothing of that. My idea was, to rotate the lines of the basic sketch to get a closed body. Looks like this: [image] How to close the outlines to a body?

You should use the Loft tool : https://www.youtube.com/watch?v=SsBv4zUf_-8

@Robin This ScreenShot shows the only Profile used to Tools > Loft the entire Wing + Pod: [IMG_0772] If something like this is not exactly what you are looking for it is just a case of adjusting Spacing between Profiles, varying Scaling between Profiles and probably making fine detail changes to…

@Robin You have talked about Tools > Revolve ‘a Body’ and did not receive a response directly related to Rotate, may I correct this now. It may, hopefully, help others also? Firstly a Body is always created from a Closed Sketch, no Closed Sketch = no Body. Taking a similar Profile to your own: […

@Gelphyn Thanks, exactly what I need. Your sketch works fine. My sketch is the problem: I can‘t select only one half of it. I created it by drawing the lines upon a imported picture in one piece. [image]

@Robin That is really good news. Please can you say which of my Sketches helped, seems it was the Profile? If that is the case how did you progress from that point? I.e., How did you use your version to get the result you wanted? The answer may be useful to anyone reading this.

@Gelphyn Right, it was your profile sketch. The problem was my sketch, I had to make my airfoil sketch completely new to get a closed sketch/body at the center line. No closed body, no loft. Since I had recognized this it worked fine. Thanks for your help.
