Cutting out ovals.

[Terry Davis]

Not to long ago I got the cutting out circle issue solved by splitting the circle into 2 arcs, today I tried cutting out a vanity top that has 2 - 19x17 oval bowls in it. I sent the DXF to the machine but the ovals are not showing up in control nesting. I used 2 seperate arcs to form the ovals on a chaincompin layer. I have attached the file for anyone to look at.

Hi Terry. There is no file attached but in the meantime try splitting the oval up into more arcs, maybe quarters, and make sure that the end points are joined.

It would not let me attach a dxf file.

Terry it is probably best to zip it first.

Terry,

Most likely, the problem you are encountering is due the fact that ovals are not made up of line or arc segments. They are usually made up of splines. If you will convert your oval (ellipse) to line or arc segments I think you will find that it will nest nicely.

Note: Depending on the size of the ellipse and/or the segment length of your line/arc segments it can take a little longer to process the nest and write code.

If you continue to have problems, email your dxf to program@thermwood.com and we will have a look at it.

Thanks,

[Terry Davis]

Thanks Pete, worked like a charm!

For those that may be using AutoCad, set the PELLIPSE system variable to 1. Then draw the ellipse on the appropriate layer per the instructions in the Control Nesting manual.

The properties of the ellipse when LIST'd show up as a polyline, but nested fine at the machine and did not error when writing to code. This ellipse can also be EXPLODE'd into arc's.
