STL to SVG Converter
Project an STL triangle mesh into a flat SVG. Choose Front, Top, Side, or Isometric view and turn Solid fill on for shaded faces.

Turn a mesh into a flat drawing
This converter projects the triangles in an STL file onto a two-dimensional SVG canvas. It is useful for mesh diagrams and illustrations. Front uses the X and Y coordinates, Top uses X and Z, and Side uses Z and Y; the Isometric view combines all three axes. The output contains projected triangle paths, including their internal edges, rather than a cleaned silhouette or a cross-section.
Why Choose Our STL to SVG Converter?
Choose the output that fits your task and inspect the converted file before using it
Four views
Choose Front, Top, Side, or Isometric from the conversion options.
Triangle paths
The SVG contains the projected triangle geometry, including internal mesh edges.
Optional shading
Solid fill adds grayscale faces using triangle orientation and depth ordering.
Browser processing
The projection runs in your browser without sending the STL to a conversion server.

How to Convert STL to SVG
Select a source file, run the conversion, and check the result
Select an STL mesh
Choose an ASCII or binary STL within the upload limit shown by the tool. Keep the original mesh for 3D edits.
Choose the projection
Open the conversion options and select Front, Top, Side, or Isometric. Leave Solid fill off for wireframe edges, or enable it for shaded faces.
Inspect the SVG
Convert, preview the drawing, and download it. Check the orientation and overlapping edges in your SVG editor before using it in a diagram.
🔧 Conversion Details
What the projection contains
The converter reads ASCII or binary STL triangles in your browser, projects their vertices into the selected view, and fits the drawing within a 500 by 500 SVG coordinate area. Solid fill adds grayscale shading, removes back-facing triangles, and draws remaining faces by their average depth. Intersecting or overlapping surfaces can still need manual cleanup.
An edge-on mesh can have no two-dimensional extent. Choose another view if conversion reports this.
The SVG is fitted to its projected bounds; STL has no unit field, so the download is not a dimensioned manufacturing drawing.
Solid fill is a simple shaded projection. It does not calculate a clean outline, a section, or an exact visibility solution for intersecting surfaces.
Troubleshooting the result
The mesh may be edge-on, or Solid fill may remove all visible faces.
Try another view. Turn Solid fill off to inspect the wireframe.
Each STL triangle becomes a path, so triangle seams and rear edges can appear.
Use an SVG editor to remove unwanted edges. Use a CAD section or silhouette tool when that is the drawing you need.
STL has no unit field and the SVG is fitted to a drawing area.
Keep the original mesh and establish the required scale in your target application.
