ESjaavik,

The geometry calculator is not completely finished, so the non functioning parts are currently disabled.

I've just downloaded it and given it a go ...

It can't handle "splines" that have been imported as part of a .dxf file can it?
File created in AutoCAD 14

DanO,

If you still can't convert your file, you can e-mail it to me and I will have a look at it.

Scott,

I'm attaching a sample drawing for your perusal.
I would appreciate it if you could have a sqizzy to see what you think ...

Scott,

Sorry, you're probably after the .dxf file ...?
I'll send that as well.

Dan,

NCPlot currently does not read in SPLINE entities from the DXF file. The reason for this is that the G-Code language does not support splines directly. So splines must be broken up into lines and arcs which is what G-Code can read. This can probably be done by Autocad when you save the file by saving splines as polylines (don't know how you do this in Autocad). I'm attaching your sample file which I saved as polylines and the resulting NC code.

Scott

Scott,

I was starting to get a feeling that you were going to say something like that ...

I've just been told by ger21 :-

"There is also a spline to polyline Lisp program freely available that will do the same thing, but will let you decide on the # of segments. You can get it here: http://new.cadalyst.com/code/browsey...?fullyear=2003

It's from December, 2003

Thanks ~ I appreciate your help.

Regards,
Dan

Dan. Like I said in that other thread, just save as version 12 .dxf and it will make the splines polylines automatically. If you're happy with the results, you don't even need the lisp.

ger21, Saving to AutoCAD12.dxf worked better than I expected ...
Thanks a lot for your help !
