STEP file to image, for profiles
Need a clean image of an extrusion or pultrusion from a STEP model? For a constant profile you don't need the full solid — the cross-section is the product. Export the section as a DXF (or take it from the drawing), drop it in, and Dimviz produces a dimension-true render and a datasheet in seconds. STEP solids describe the whole part; profiles are defined by their section, so the section is all Dimviz needs.

STEP is a solid; a profile is a section
STEP (.stp/.step) is a rich 3D solid-model exchange format. For an assembly or a machined part you'd open it in a solid modeller. But an extrusion or pultrusion is a constant cross-section swept along a line, so its section — exported as a 2D DXF — fully defines its shape, weight and stiffness. That's the fast path Dimviz takes.
From section to shippable image
Upload the DXF section, choose a material and finish, and export the render and dimensioned drawing. Because the output is vector-clean and the numbers come from the same section, the image is presentation-ready and the datasheet is traceable.
FAQ
How do I convert a STEP file to an image?+
For a profile, export its cross-section to DXF and upload it — Dimviz renders the extruded section and computes its datasheet. Direct STEP import for constant sections is on the roadmap.
Do I need the full 3D model?+
No. A profile is defined by its constant section, so the 2D section (as DXF) is enough to render it and compute every property exactly.
What image formats can I export?+
Clean vector SVG today, with high-resolution PNG export for renders and datasheets.
