Export DXF changes polyline direction

[Bertf]

Hi,

 

I've noticed that the DXF export sometimes changes the polyline direction. This behavior happens since VW2021. Before I didn't have this issue.

It's really important for us to keep the polyline direction as we use these lines for milling on our CNC machine.

 

In the file in the attachement you can find 2 design Layers. The first one is "Export". Here I have 2 polylines with the direction as show in this image from top to bottom.

 

 

After exporting with these settings:

 

I noticed that the right polyline has it direction inversed during the export.

 

After importing, you can see this in the "Import" design layer:

 

 

 

Is this a bug, or some settings that has to be changed?

 

Thank you,

Best regards,

Bert

Any news on this topic? Am I doing something wrong, is there a setting off? Or is this just a bug? Definitely not resolved in VW2021 SP3.1 Build 588748.

No one at Vectorworks support that can acknowledge this is a bug or not?

Hello @Bertf,

 

I will take a look at the issue and will let you know if this could be somehow avoided. 

 

Thank you for reporting,

Nina

Great, thank you!

Hello @Bertf,

 

Change of the direction of some of the polys, which contain arc type vertices, has been intentionally done in order to fix a problem, introduced in the third party libraries with associated hatches. Since you do not export hatches, more over your polys are not hatch filled, reversing of the polys is absolutely not necessary. I consider this a bug, which however needs to be fixed in the code. We will do the necessary corrections.

 

Thank you,

Nina

Thank you for looking into this and marking it as a bug.
