Title: Lines joined with arcs cause problems - turbocad
Post by: StanLewis on July 18, 2008, 09:42:26 PM

I drew the following drawing using turbocad.  Save as dxf then onto LCam.  LCam generates more than the six chains.  According to Scott the problem is in the dxf.

What the heck is going on?

Hello Stan,
I opened your file in AutoSketch9, grouped the entities and got the following in LCam.
6 chains.

OK now what the heck is TCad doing to the file when exported?

The .dxf looks fine to me. When I open it in AutoCAD, it's 6 polylines. Perhaps LazyCAM is not reading it correctly?

Hi, Stan

Your dxf has allot of extra items in it, Copy the item you want to use, Then open a new drawing and past it there, Then use it in LCam.

wow that figured out my problem that I was having. What does copying do to the dxf.

Hi, Davy182

In the case above the original dxf had allot of extra trash in the drawing (pic 1), Copying and pasting only the  wanted item Pic2 to a new cad/dxf drawing file.

It's just starting with a clean drawing leaving the trash behind, Sometimes deleting un wanted items doesn't really delete them  properly.

Hope this Helps, Chip
