I can’t seem to get shapr3d to scale my svg export correctly. No matter what DPI I enter when exporting, the svg has the same dimensions. I’m testing it in Inkscape right now. If I export a 10mm x 10mm square its dimensions in Inkscape is 42mm no matter what the dpi value is? It also adds a brim that is a couple of mm away from the actual edge which also ads to the whole thing being wrongly scaled. In the screenshot I’ve use dpi of 30 and of 300. Same size?
Is it just not possible to use shapr3d if I need svg files? Or what am I doing wrong?
SVG exports from Shapr3D use real-world units (mm), so DPI doesn’t affect the size. Inkscape may scale it based on its default settings (usually 96 DPI), which causes the mismatch.
Thank you Lys for the reply!
That make some kind of sense, but why is it then possible to alter dpi when exporting form Shapr3d?
And what is the scale from “real-world units” too lets say 96 DPI? If I knew the scale before hand I could just scale down the sketch in Shapr3d before exporting.
I don’t know anything about DPI so I apologize for these maybe ridiculous questions.
Scalemodel thank you for your input! I guess this will probably be the end to it as well; me scaling the file with something that might be the right factor. It is just so frustrating when I should be able to not have to scale it at all.
Regarding the padding I think that it is shapr3d that adds ot as it is the same scale issue I meet when I import it to Luban (my slicer for my Snapmaker 2.0) . This means that I have to measure the padding. Approx 2mm in each side. So the scale is 10:38 (42mm-2mm-2mm) 0,2632… maybe.
Okay so the real problem is not a 1by1 square. It is a bigger part. My issue is that when I import it to Luban, it automatically scale it to fit to the building area. This eliminates my possibility of scaling it correctly even if I knew the correct scale as I don’t know by how much the program has scaled it down to fit the plate in the first place.
Therefor I have a wish of exporting the svg to the correct size.
I could maybe ask you all another question: what is your workflow when you’ll need a 2d sketch in scale from shapr3d?
I personally try to avoid SVG but understand it’s popular in cutting software.
Have you tried DXF I don’t have any scaling issue using that format.
I’ll try to fire up a VM and try Luban.
But my general tip would be make a box the size of the maximum build area of the printer in Shapr and place what you want to cut or build within that space and export it.
When in you import it in Luban you easily know how to scale.
Thank you so much for your help!
I saw your post yesterday where you suggested dxf so I went I tried it out this morning. And it worked. And now I see you also have tried it out. Simply fantastic!
I will be using dxf from now on. I’ve tried it before I tried SVG but had some results where the file was just blank. So didn’t think that worked (but I must have made some mistake).
I’m more of a CAD kind of guy so dxf is to prefer anyways.
I still don’t get why there is a dpi setting when exporting from shapr3d. I’ll try to ignore it and let it go.
