Control point issues when importing DWG/DXF files

Hi,

I often use Illustrator to draw reasonably complex 2d shapes that I then project onto surfaces so I can extrude them as relief patterns.

When I export a DWG or DXF file from Illustrator and import to Shapr3D, everything appears to be working, but I run into issues trying to extrude with Shapr3D’s control points. Shapr3D doesn’t seem to know the difference between an anchor point and a Bezier handle.

This is incredibly tedious when you are importing a complex path (i.e.: thousands of points). When importing a DXF/DWG, shouldn’t Shapr3D be able to tell the difference between an anchor point and a Bezier control and add the control points automatically? It would literally save me hours of tedium.

I have to do this point by point, often waiting while Shapr processes the changes between clicks. Also, I can’t shift-click multiple points and then set them all as control points, which is also frustrating. And I have decipher where to begin with paths that look like this…

Any suggestions or advice?

PS: Love the software. Thanks.

I moved over to Affinity Designer from Illustrator because they introduced DXF/DWG export last year so this is true for both AD and AI.

Bezier feature is different in CAD like programs including Shapr. You don’t get the handle bars. It’s bit of a hybrid, In AI or AD you can use the handle bars to make sharp corners but in Shapr you need to turn them into a corner. Also the reason why they call it Control Splines vs Bézier curves.

The question I would have are why do you need to move the control points? Shaprs vectoring tools is more geared toward cad work instead of Vector Art. So if you need to change the control points it would be more productive to do on the AI side and reimporting on Shapr.

Your Second question is extruding the projected Sketch. Is the surface flat or curved? Also why do you need to move the control points so that it can be extruded?

Yes, I want to project vector shapes onto curved surfaces.

In Illustrator, my vectors are fine. In Shapr3D, without the control points, the curves themselves change and cause all kinds of errors when I try to project them. Here’s an example (I can’t post videos).

So I guess I’m making a feature request. Give me a check box that turns all vector points into control points. Pretty please with sugar on top :grinning_face:
