Tim, i am not good at all in sketckup, but i do find a way to manage to draw what i need...the easiest way for me is to go to the airfoil page. http://www.ae.uiuc.edu/m-selig/ads/coord_database.html save the foil i want by clickin on the gif of it, then right click and save picture as a bitmap file. then import it into sketchup, make it super big, then just trace it with a series of lines. its simple, and it works for me. when your done just scale to suit your needs. randy.

 

There are a few RB plugin files out there for different arc's I have one but not here I will have to look when I get home from work.

Ok I found it. It's called "Bezier Splines" and here is a good page on it http://www.aecbytes.com/tipsandtricks/2 ... tchup.html

Hope that is what your looking for. I have only used it a few times.




Cheers
