Polylines with real arcs for CNC Router?

[TDahl]

@DaveBryce

With my SU 2017 the amount of segments added to arcs with short lengths is very limited. This means if i wanted to use a high amount of segments then i have to go back to SU 2016 or draw very large scales in SU 2017 and then scale them down, two solutions that are highly undesirable.

I suggest that you try the “Dave method” for dealing with SketchUp’s inability to directly create very short edges. It avoids the need to scale back down (which might introduce mistakes in one’s workflow):

The Dave Method

The Dave Method is the clever use of components popularized by @DaveR to avoid the tiny face issue. Sketchup fails to form faces when edge segments get down around the 1/1000" mark. However, tiny faces can exist so the workaround has generally been to scale up your geometry, edit it, then scale back down. This works, but can lead to some issues. The Dave Method leverages the power of components to make life easier. The basic concept is, you start with a component set at the size you want, t…
