    Cutting !@#$% Arcs...

    I'm sure this has been beaten to death somewhere, I just can't find any info on it.

    (Turbocad v4, AceConverter).

    When I try to convert a DXF that has arcs, the G-code goes off the deep end!

    I can cut ribs, any font of text and simple shapes just fine.
    When I try to convert arcs of any kind, the G-code sees it as a huge circle off in negative X and Y land.

    I'm trying for a simple turtledeck former.

    Help!

    Make sure you are NOT selecting "I and J are incremental" on the convert screen in Ace Converter.

    I wish it wouldn't crash.

    I'm not. I tried all combinations of boxes checked or not, all to no avail.

    Can you look at the DXF and see if I did something wrong?

    In 3D view, its all messed up. The arcs are not flat on the z plane. Entities do not connect.

    I see...
    I noticed that in the G-code, as the Z was doing funny things.
    I guess I will have to work on my CAD skills some more.

    Thanks a bunch,
