I exported a sketch created in Shapr3D to SVG, but it was output as a bunch of straight lines instead of Bézier curves.
How can I export it as it was drawn in the sketch?

Try DXF instead of SVG.

I’ve already tried with DXF, however…

SVG exports is resolution dependent which is why you get bunch of lines. Increase or descrese the value below you get more or less lines

The problem is not that there are many straight lines, but that all curves are replaced with straight lines.
I want to export the drawing without losing any curves.

Yes the curves are converted to lines, for example if I create a circle and exported as SVG they become a polygon when I import it in another graphic program not perfect mathematical circle. I believe thats what you are encountering.
So curves saved as SVG looses the Bezier Handles, my initial suggestion was DXF because exports keeps Bezier Handles, but not SVG.

I understood your earlier suggestion, but the result was same as SVG even I exported to DXF.
Now, I’ve found it’s the problem of Affinity Designer 2, the vector drawing tool I am using.
When I re-import the exported DXF file using only Shapr3D, it keeps the curves.
But they are lost when I open with Affinity Designer 2.
I will try to find some applicable bridge converter for this situation.
Thanks anyway!

I do lot of Affinity Designer to Shapr3d.
I have not encountered the issue you have with DXF. DXF usually gives me bezier so that is my go to file format when I need it in Affinity Designer.
I can recommend QCAD as a converting software, it has 10min time trial.
I attached test files from Shapr to DXF to AD, it shows what I see.

Hi,
I did a test with Adobe Illustrator.
In AI, draw a circle and export it in .dwg
In S3D, import it. The circle keep Bezier Handles.
In Ai, open the .dwg file and all is OK.

Try this, Jean (I don’t have AI).
- Make a circle in Shapr3d and export it as SVG.
- Make a circle in Shapr3d and export it as DXF.
Import it in Adobe Illustrator if you get segmented circle or pure curved circle.

Hi,
- Not good > segmented circle with a lot of points
- Not good > just an horizontal line
BUT
If i export with DXF from Drawing, it’s OK. A pure curved circle.

What orientation is the sketch in? Is the sketch Facing the Front?
If sketch is facing some other direction try to make it face the Top down.

That Control Spline issue looks like what the Original Poster was encountering.
I kinda know why, Control Splines are NURBS Curve. Fit Spline is more like Bezier Curve.
AI and Affinity Designer don’t have built in NURBS Curve so it looks like it’s converting it to segmented curves with high resolution.
So as far as I know only software that can convert Control Spline Correctly is RHINO to PDF. If others have better conversion method, please post.
