A .crv3d file is an Aspire project: 2D vectors, text and toolpaths like a VCarve .crv, plus
3D components combined into a model. Only Aspire opens it. Upload the project here to get both
parts out without Aspire.
The vectors: SVG and DXF
- True size, in the project's units, with one layer per Aspire layer.
- Arcs and curves kept: true arcs and Bézier curves in the SVG, arcs as bulges and fine polylines in the DXF.
- Text as outlines, placed as in Aspire, and pictures embedded in the SVG.
- Two-sided projects give one SVG and DXF for the top and one for the bottom, in a ZIP.
The 3D model: STL and height map
Aspire keeps the model it displays, the combination of all visible components, inside the project. The converter exports it as:
- an STL solid, closed (with walls and a thin base), true size in millimetres, sampled at up to 400 points along its longest side;
- a 16-bit greyscale height map (PNG, up to 4096 pixels), black at height 0 (or at the lowest point, if lower), white at the highest, with the heights given on the result page;
- a shaded picture of the model seen from above, to check it at a glance.
Projects that save no combined model, such as a project with a single component or a VCarve project with an imported 3D model, give that component.
What is not exported
- Toolpaths, including 3D roughing and finishing: they are listed with their names and kinds, to set up again in your CAM program.
- Component settings: how each component was shaped, its combine mode, fades and tilts. Only the resulting model comes out, as Aspire showed it when the project was saved.
- Textures and materials used for Aspire's 3D rendering.
Check the model
Compare the shaded picture with the 3D thumbnail Aspire saved in the file, which the result page also shows. Then import the STL into your CAM program, check its size and depth against the material on the result page, and run an air cut before machining.
