SVG to 3D: a logo, an icon, a plaque
Drop an SVG, set the width and the depth in millimetres, and get a solid model of its outlines: GLB for a web viewer, STL for a slicer, OBJ for a 3D tool. Each shape is filled and extruded on our server with Blender's SVG importer; the page reports the final size and the triangle count.
The longest side of the drawing becomes this.
STL and OBJ are written in millimetres, GLB in metres.
What becomes geometry
Paths, rectangles, circles, ellipses, polygons and polylines, with their transforms and groups applied, are read as outlines. Each closed outline is filled as a flat face and extruded to the depth you set; a path with a hole drawn inside it (a letter O as one compound path) keeps its hole, while a shape drawn as a separate element inside another is a second solid on top of the first. The whole drawing is then scaled so that its longest side is the width you asked for, and set with its base on the ground plane.
Strokes are not modelled: an outline with a stroke and no fill is filled, because an extruded line of zero width is nothing. Text has to be converted to outlines in your vector editor first, and a raster image inside the SVG has no outline to extrude; both are refused by name rather than silently left out.
What this tool cannot do
Outlines only
Gradients, stroke widths, dashes, masks, clipping and filters do not exist in a solid. The fill colour is not carried either: the result is one material, to be coloured in the viewer, the slicer or the 3D tool.
Overlaps are not merged
Two elements that overlap become two overlapping solids, not one. Slicers cope; a boolean union in your 3D tool is the clean fix when it matters.
Fifty thousand curve points
A drawing with more control points than that is refused as too complex. Simplify the paths in your vector editor; a logo needs a few hundred.
Three days, then gone
The upload and the result are deleted three days after the job, downloaded or not. The page keeps no history: bookmark the download or take the file while it is there.
Frequently asked questions
Why is my SVG refused with no shapes?
Either it holds only text, which must be converted to outlines first, or only a raster image, or its paths are open lines that enclose no area. The refusal says which.
What size will the model be?
Its longest side is the width you set, in millimetres; the other side follows the drawing's proportions; the depth is the depth you set. The report lists all three.
Which format for 3D printing?
STL, written in millimetres so the slicer shows the size you asked for. OBJ is also in millimetres; GLB is in metres as glTF requires, and a viewer shows it at the right size.
Does a hole in a letter survive?
When the letter is one compound path, yes: the inner contour is a hole. When the inner shape is a separate element, it becomes a raised shape instead. Most vector editors write letters as compound paths when you convert text to outlines.
Can it keep the colours?
No. A solid has one material here. Colour it in the viewer, the slicer or the 3D tool; for a two-colour print, export the two colours as two SVGs and combine the solids.
