Cannot extrude an irregular edited shape

Hi there.

I’m new to umake, however I have experience in 3D design.
I’m trying to create a replica of a car badge, which is very irregular. My approach was to create a shape using splines (either by precision or sketching) , I close the shape but the autosurface seems not to be aware of that. I then assumed that the shape wasn’t probably correctly closed. I started over, making sure that every point connects to the next. No way, I’m missing something or the program is not doing what’s expected.
In my third attempt, I draw a sketch in one single trace, as close to the final shape as I could. This time, the surface was completed and it turned to blue in color. Okay, I finished it then by touching the green button. I spent about 20 minutes editing the shape to make it fit to the image I had in a lower layer. Then I tried to extrude the shape into a volume. The only thing I could extrude is the border line, no chance to extrude it into a volume. I’m not sure if that’s is actually possible? Watching the videos I only can see that the extrusion process seems to work only with shapes made of one single trace, but I didn’t find a tutorial where you edit the shape and then make that it into a volume by extrusion. For example, say that you draw the shape of a dog. Then you edit the shape to make it look more like a dog. Then you extrude that shape pretending to give the dog a volume, then you discover that only the shape is extruded , not the surface, leaving kinda a box with the shape of a dog. Am I doing wrong or is it a missing feature? I don’t discard I misunderstood the procedure. Is there a trick to make the edited shape extrudable as a volume?. Thanks.

Hi @alexmake

Thank you for contacting us here!

Would it be possible for you to upload a screenshot of your creation? Maybe even attaching the original .UMK file?

I suspect the surface created is not a planar surface (it means it’s 3D) and therefore, this prevents you from pushing or pulling the surface itself. We’re working on improving this experience, so it would be easier to push/pull 3D surfaces.


Hi. I’m attaching screenshots of my last try unfinished. One is just the shape, the second is the same shape as I select it and the third is the extrusion. It extrudes only the contour, since it does not interpret it as a planar. If this is a non-closed-shape problem, I can say that it’s not easy (at least for me now) to close a shape and make it a surface. I tried as I said, drawing a shape with one single trace , but as soon as I try modifying it to accommodate the shape, it is not a surface anymore. Correction : the forum only let me upload two images because I’m new to it. So, the first one is the shape in edition stage and the second the extrusion.

I’m trying to get the .umk file for you…

@alexmake I changed the rules so you an upload more images now.

Hi. Sorry about the delay. I’m attaching the model as exported from umake. Hope it helps.
Note: export produces a zip file, containing the base image I’m using and the model. Unfortunately, the forum rules only let me upload image files and .umk. There were a couple of more files inside the zip files (.astc & .png) that I’m not uploading here.
Let me know if this is okay for you.model.umk (3.3 KB)

Hi @alexmake,

I think the issue was with the curve itself - it was too complex as one unified curve, and what I did is simply disconnect one of its control points so that it will behave as two lines connected. (705.3 KB)

You can import the .zip as it is into uMake.

I also improved the tracing by adding more control points so it would be closer to the original photo.

P.S. uploading .zip files in the forum is working now.

Let me know if this helps.
