Question 1

What are STEP/STP files?

Accepted Answer

STEP (.step/.stp) is an ISO 10303 CAD exchange format for sharing exact 3D geometry (B-Rep), assemblies, and metadata between CAD systems.

Question 2

Why does STEP take longer to load than STL?

Accepted Answer

STEP stores exact CAD solids/surfaces and must be tessellated (triangulated) into a renderable mesh. STL already contains triangles.

Question 3

Shin files uploaded to manuals.plus?

Accepted Answer

Drag & drop and file uploads are processed in your browser. If you load from a URL, your browser fetches that URL directly (subject to CORS).

Question 4

Me yasa URL loading fail sometimes?

Accepted Answer

Browsers enforce CORS. The host serving the .stp/.step file must allow cross-origin requests (Access-Control-Allow-Origin) or you will need to download the file and upload it here.
