Drawing curves

mack5

Hi
I am new to SkUp, I like to scan some sections to make a r/c airplane into skup, I can import them as a autocad.dfx file so how do I trace them into Skup to make sections? What is the best way to make curves smooth in Skup? are there any pluging that will work?

Thanks

I think there's a lot of reference material that may help: search the User guide, help and forums.

Sketchup has an Arc command that can make curves over images.
However, the more effective way of tracing curves over images is with Bezier splines, just as in Inkscape, Photoshop, and I think even Gimp.
There is a Bezier plugin by Fredo, that can be found in the Plugins directory. I can tell you, that I had to practice this a lot until I could get good results, and understood the spline.

Hi everone
Can you edit / make changes to a line or arc after you draw it like in a cad program ? Or can ployline shape be change.

If I trace over something like a boat section using arcs, the lines do not look good in skup, can I click on a line, arc and change it's shape by moving the grips to improve the shape of line?

Thanks

Hi,

Yes, but you'll need Fredo's Bezier Spline plugin. It right at the end of the first post. It also comes with extensive documentation.

Did you know you can change an Arc's segment count before you draw? Once you select the tool look at the VCB. Here you can type how many segments you want.
