STL to STEP Assistant vs PocketSpec

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. Built for mesh-to-STEP work - Convert STL, including binary STLB, to STEP - Convert OBJ, GLB, GLTF, 3MF, 3DM (Rhino), FBX, DAE, PLY, USDZ, 3DS, AMF (additive manufacturing), DRC (Draco), KMZ (zipped 3D scene), MPD (multi-part LDraw), and WRL (VRML) model formats to STEP - Load and view STEP files to inspect conversion results - Export STEP with BRep reconstruction, useful for turning some engineering mesh models into easier-to-edit CAD surfaces - Preview 3D models and BRep reconstruction results before export - Export the current main model, not the whole scene or other objects - Keep floor, lights, camera, and visual effects out of the STEP file - Process files on device, so model data stays on your device - Privacy focused, with no account, no login, no ads, no tracking, and no data collection Choose STEP export geometry and quality as needed - BRep: tries to convert suitable mesh models into easier-to-edit CAD surfaces, useful for some engineering parts and regular geometry - Faceted Small: fast, lightweight STEP export for everyday use - Faceted Balanced: balance detail and file size - Faceted High: preserve more model detail - Faceted Original: export as directly from the source mesh as possible Understand the result before saving - View source file information - Review mesh, triangle, and vertex counts - Check triangle reduction by quality mode - Get a simple export risk hint - See the final STEP file size after conversion It is made for makers, engineers, designers, 3D printing users, CAD users, and anyone who needs to convert mesh models into STEP exchange files. Pricing & Access - Free: Open, preview, inspect models, load STEP files, and use Small STEP export. - CAD Surface Export unlocks BRep STEP export for suitable models, helping produce easier-to-edit CAD surface results. - In-App Purchase unlocks: Permanently unlock CAD Surface Export, Balanced, High, Original, and other STEP export capabilities.

PocketSpec is a read-only viewer for comfortably reading the Markdown specifications inside your GitHub repositories, right on your iPhone and iPad. Check the design docs and specs stored in your project's docs/ folder anytime, anywhere. It isn't tied to a single repository — register multiple projects as a "spec bookshelf" and switch between them to read. ■ Key features • GitHub integration (read-only) Sign in with GitHub and securely fetch only the contents of the repository, branch, and documentation folder you specify. It never edits or commits files. • Clean Markdown rendering Supports headings, lists, code blocks, tables, images, and links. Optimized so even long specifications are comfortable to read. • Mermaid diagram rendering Renders Mermaid code such as flowcharts and sequence diagrams as real diagrams. Tap to zoom to full screen. • Manage multiple projects Set a repository, branch, and display folder per project. The last opened project and document are restored on launch. • Offline support Once fetched, content is cached on device, so you can read your most recently synced specs even with no connection. • Secure by design Limits the visible content to the folder you specify; it never reads source code or configuration files. Access tokens are stored only in the device Keychain and are never sent to any external server. ■ Who it's for • Engineers who want to quickly check their project's specs on the move or before a meeting • Anyone who wants to read documentation from multiple development repositories in one place • Anyone who wants to safely view private-repository design docs from their iPhone ■ Before you start Using this app requires a GitHub account and read access to the target repositories. To read private repositories, install the dedicated GitHub App on the target repository (the only permission required is Contents: read-only).
