Thanks, I have to try to figure out what I am doing wrong.

There is not much that we can do about the DXF's that don't load We have an OCX that we are running... therefor we can't do much.

One of the reasons that DXF won't load has to do with Scaling/Size issues. 

I noticed this after using a .jpg to .dxf converting program.    The conversion/trace went great but it would not load in LCAM.  I opened up the .dxf in Autocad and discovered that somehow in the conversion, PIXELS were misinterpreted for units (in my case inches) and my drawing was like 9500 Inches tall.

This made LCAM very grumpy until I used ACAD to rescale the drawing to the size I really wanted it to be.  The LCAM welcomed with open arms

CAD programs usually have so many options/variables associated with units and scale that I think it's easy to get confused.  Try scaling things down and see if that helps.

Also, Blocks in CAD programs will not be seen in LCAM.  Explode all your blocks before you open in LCAM.

HTH,

Sid
