Hallo, I’m struggling a lot with my imported curves. Oject: importing topographic lines (closed curves) to 3D model them and 3D print. Import is a DWG file from Corel Draw with 2 closed curves: Topo_600R_closed_smooth_nodes_test.zip (17.1 KB) Corel Draw has 3 types of nodes for curves: cusp, sm…

The arc changes the the point from an end point of a line segment to a control point connecting them together I think. If you had 2 line segments connected it combines(?) the two segments? That’s why it changes the line I think. For some reason your segments aren’t connected if they do not create c…

Thank you for finding some interest in my problem. I narrowed it down a little bit an I am now quite sure that it is a Corel export problem, maybe due to the Bézier curves. My Corel is the 2018 version. Exporting as SVG and then saving the SVG to DXF with Inkscape gave me some options while savin…

My prior version was Corel X6. It has always worked fine exporting as DXF. Never tried DWG. [image] First X1C and Shapr multicolor project +1 Share your creations Finally got my X1C and 2 x AMS units set up and running. Minor kinks to work out with the filamen…

[image] gBivi: BUT after some mm the drag arrow gets red . I notice that too. Bug? If you offset (outward) the offset again you can go twice as far before it turns red. Strange. The ARC icon toggles “cusp” function I believe.

Lion.shapr (28.7 KB) In this sketch I have the same problem, on the inner loop of the tong I can do a 0.3mm offset edge, but not more. Can somebody explain this? THe outline shape of the lion can not be offset at all. Why? I checked each Endpoint for its connection, I UNCONNTECTED each Endpoint,…

I moved that control point and was able to do an inner offset as much as I wanted. [ControlNode]

Noticing some things here. Maybe it is as you intended but they look worth examining. I made a rectangle around the design and tried to offset it. It did not work. I will play with it some more. Can you attach the Corel file? Corel Draw has a “Reduce Nodes” function. Have you tried that? Some of th…

Also: I suspect the Tongue area is key to the offset problem but that is just a guess. The offset might be better done in Corel first. If you send the file I could better help. I don’t charge :blush:

Yes you are right for doing the offset in Corel, but it is a project I want to do with my students and they do not have Corel on their iPads, but shapr3D . To the marked Endpoints in your screenshot. The unconnected blue to orange lines should be like that. I opened these connections to simplify t…
