When I make text on a sheetmetal part everything works fine.
I disolve the text after I've got what I want. I put in the
appropriate 'bridges' and I'm done.
The problem is, when I import the dxf file into SigmaNest to make a cut file, all the arcs in the text become short lines. When the laser gets to those lines, it hesitates and 'jumps around'. When it comes to a true arc, it cuts fine.
Is there a way, besides putting in new arcs in the text, to fix this??

I'm guessing that SigmaNest does not use splines, and the splines are being converted into short line segments. I have tried exporting from SolidWorks using the "export all splines as polylines" option which generates arcs; however, my results are poor. It may be that I am missing some "quality" or tolerance setting to break the splines into smaller arc sections for better accuracy.
I know there are a couple free spline to pline converter scripts for AutoCAD. (Unfortunately they do not work with the DWGEditor.) There are also a few stand alone converters to generate arcs from splines in a DXF/DWG that are reasonably priced.
I'm hoping there is a good method to do this quickly in SolidWorks. If there is not a tolerance setting, using the "split" tool may achieve the same results at the expense of time.
UPDATE: I increased the image quality and performance settings but did not get any improvement in the dxf quality.
I did use the "split" tool on the splines that were causing problems and was able to increase the number arcs for better quality. I am still looking for a setting that will break down the splines automatically. Perhaps someone has already created a script to do this.
