Thermwood and circle top.

[Terry Davis]

We are trying to cut out a 48" dia. table top out of 1 1/8 material. We are sending this to the machine as a DXF file when loading and selecting my material I get an error that says"The material selected for the Dxf part D:\ -part name- has the incorrect thickness the required thickness required is 0.0000. The dxf will not be in the nest" I've tried everything even making a new dxf template, if I change that circle to a square it nests perfectly.

Try breaking the circle into at least two arcs. Circles are assumed to be for drilling only, therefore CN doesn't see anything on the outline layer.

When I break the circle into arcs I get the error " A common close point was not found for an outline operation" if I remember right all outlines have to be a closed entity.

[David Hall]

Perhaps I should have been more specific.

Two arcs, each 180 degrees with the same radius and same center point arranged such that they create a closed circle.

Like the one attached.

Dave

Control Nesting(CN) needs an endpoint to start from.

Terry,
Yes, all outlines need to be close entities. A square is a closed entity and has 8 endpoints (startpoints) for CN to start from. The circle you are using has zero endpoints. Like David said, break the circle into 2 pieces, and you should be fine. If you need further assistance with your dxf file. Post it, and I will take a look at it.

Note: Make sure you are running the latest version of control nesting. We are up to Version 5.38

Thanks guys got it working, I was using the break command to break the circle, once I used two arcs it was fine!
