Problems in CAM with the function "Parallel with Distance"

Hi,

got some problems with using the parallel tool.
When I have a line with arcs and i want to create a parallel line with distance, Librecad makes the parallel line but its not continues. So i cant use the drawing for cam!

does anybody know how to create parallel continous lines with librecad?? The Copy function in this case cant help...

Regards

Rallaz

You want to get the result of making a parallel to a polyline using lines and arcs.

The solution is:
1- draw->polyline->create polyline from existing segments
2- draw->polyline->create equidistant polylines

hey,

a other, and possible better solution is to program your cam software

and use cutter compensation G41 and G42 see : http://www.linuxcnc.org/docs/html/gcode/gcode.html#sec:G41-G42

and http://www.linuxcnc.org/docs/html/gcode/tool_compensation.html#sec:cutter-compensation

This way you don't have to do the offset at all. A other advantage could be if you re-sharpen your tools and

your diameter get's somewhat smaller overtime. Then using the right tool number you can enter in your tool

table the new diameter after sharpening. and you will always cut on the right size.
