STL to STEP Assistant
Mesh models to STEP files.
STL to STEP Assistant launched on May 24, 2026.
What it does
STL to STEP Assistant is a focused local 3D model tool for converting mesh-based models into STEP files for CAD workflows. Open STL, STLB, GLB, 3MF, USDZ, OBJ, 3DM, FBX, DAE, PLY, 3DS, AMF, DRC, KMZ, MPD, WRL, and other model files, preview them in a clean 3D scene, choose a conversion quality mode, then export and save the current main model as a STEP file. You can also load and view STEP and STP files to inspect conversion results.
Download STL to STEP Assistant by 维 艾 on the App Store. See screenshots, ratings and reviews, user tips, and more apps like STL to STEP Assistant.
- Added BRep reconstruction export for converting some engineering mesh models into easier-to-edit CAD surfaces. - Improved the export panel, status messages, and multilingual copy. - Updated the sample model shown when the app starts.

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
