DXF Export for Laser Cutting

Other sections CAM

Hi all

I'm having an issue I don't remember having on previous versions of SW, I'm in 2021 SP3.

When exporting my part to DXF (ext outline + sketch of a logo), all the splines are cut into segments!

I looked in the export options, whether I check "Export all splines as splines" or "Export all splines as polylines" it doesn't change anything!

I attach 2 screenshots:

- logo-sw.jpg: the visual in SW

- logo-dxf.jpg: the DXF result

I have no choice but to go through a DXF or DWG because my laser cutter only accepts that...

Thank you in advance for your help.

Hello

I would say that your sketch is polygonal, it happens when processing an image via a third party software (artcam) even when exporting in spline "dxf", I don't know why!, but by going through an export "svg" then in "inkscape" I export new ones in "dxf" I get spline patterns that I can exploit with solidworks and then transfer to the cnc correctly,

An alternative method is to use the solidworks "spline tool" (adjust spline).

Hello

I think this problem happens when you create your DXF from the 3D file directly. If you generate your DXF from a drawing, there will be no problem.

Hello Pierre S,

I had thought about it.

On the drawing the spline is very beautiful, but when recording in DXF I am faced with the same problem...

I just found a solution, at least for this part, I do a 0.2mm material removal and there the DXF export gives me a spline.

Eureka!

Thank you for your help.
