**********************************************************************
**********************************************************************
**************************General Notes*******************************

DXF import:
Text must be saved as polylines in CAD program, KCam does not do Font regeneration.
In Turbo Cad set Text property "Flexible" on, or draw text using POLYLINES.

Gerber Import:

Gerber Isolation Importing has made some compatibility improvement, but is not perfect.
Please e-mail me (small) Gerber files that do not work properly along with a short description of the problem.

Gerber(RS274X) single or multiple layers is the ONLY format supported, it has the aperture list built into the file.          

Imports are limited to 100 Polygons for Unregistered users
Imports are limited to 10000 Polygons for Registered users
A polygon is derived from each Line segment or Pad from your Gerber cad program
A 14 pin Dip drawing with 2 straight traces makes 16 polygons
