What is the difference between a "SketchUp Arc" and a "true arc"? Segments! SketchUp naturally breaks arcs and circles into a series of segments in order to make surfaces for your models. In this video, Aaron shows why it is important to understand how this works and what you need to consider when modeling curved geometry.

Cheers Aaron, Another clear instructional video for the collection. Very useful & important information in there.

Excellent video on this topic. Instructive! Thanks again Aaron. I am missing in SketchUp's presets the ability to have the 24 segments in the base be different. For example 48 segments. I know you can set this before you start creating a circle, but it would be a nice addition if you could determine this yourself in the base settings. Possibly you could discuss this with your colleagues....

Alas, 24 sides is a persistant default... as an optomist, I hope to see a setting in Gen Info, one day!

I find 60 segments works well and that is also accurate when you are talking about degrees or minutes.

@mekkler Год назад

Because of the stuff I usually draw, I almost always up the segments to 32 or 64 or another power of 2. This seems to avoid a lot of problems of strange results when intersecting faces. I would even change the default of 24 segments to 32 if it was possible (or I could figure out how). I come from an Autocad background where 'entities' are stored as equations so that tangents and intersections, etc, are calculated to 12 or 16 decimal places.

had a lot of issues with exporting to dxf for cnc. i did the 2D export. Glad to learn I should do it in 3D. Thx Aaron

Thanks for clarifying the export to 3d model dxf interprets cicle as a true circle. This is something my laser cutting contractor has struggled with as I was exporting cutting profile as 2d since it was flat
