3D CAD model: wireframe to solid — simplify and analyze in the browser

Why Slimo3D

Import STEP and IGES in one click

Upload your CAD file in the browser. Slimo analyzes assemblies, parts, and geometry so you can simplify without opening heavy desktop software.

AABB OBB and more

Get axis-aligned (AABB) and oriented (OBB) bounding boxes instantly. Preview and select which parts to replace—all in the browser.

MBC and MCC for best fit (Pro)

Use Minimum Bounding Cylinder (MBC) and Minimum Convex Cylinder (MCC) for tighter, more accurate replacements. Pro only.

Export clean STEP

Export a simplified STEP with selected parts replaced by boxes or cylinders. Fewer parts, smaller files, same structure.

Works in the browser

No desktop install, no IT tickets. Open the link, upload, and go. Saves time and works on any machine.

Projects and storage

Group models by project, save inputs, and manage exports. Pro includes more storage and longer retention.
