MeshWeave.app's answer:
MeshWeave.app's answer:
STL to STEP that gives you real surfaces: planes, cylinders, cones, spheres and tori are recovered from the triangles, so a round hole comes back as one cylinder you can measure, not hundreds of flat slivers. It also opens and converts SOLIDWORKS parts with their exact surfaces and can save a newer part for SOLIDWORKS 2025 or 2024, all in the browser with nothing installed.
MeshWeave.app's answer:
Because it does the job without an install, an account or a CAD licence, and says plainly what you get: exact geometry stays exact, and meshes become real solids rather than faceted ones. Files are processed on MeshWeave's own servers, never sent to third parties, deleted within 24 hours without an account and never used to train AI. Meshes can be viewed entirely in your browser without uploading at all.
MeshWeave.app's answer:
Anyone handed a CAD file they can't open: engineers and machinists who receive SOLIDWORKS or Parasolid parts without a seat, 3D-printing users who need STEP or STL, makers moving between FreeCAD, Fusion, Blender and slicers, and teams who need a part saved for an older SOLIDWORKS release.
MeshWeave.app's answer:
MeshWeave runs entirely in your web browser, so there is nothing to download or install. The heavy lifting, turning one kind of 3D file into another, happens on MeshWeave's own servers rather than on your computer, so it works the same on a laptop as on a powerful workstation. Everything is built in-house: your files are never passed to another company's service, and they are deleted after use unless you choose to keep them in your account.
MeshWeave.app's answer:
MeshWeave started as a small browser tool for making 3D-printed parts lighter and better looking: filling them with lattices, adding textures, without buying or installing expensive design software.
It ran into the same wall again and again. Before you can improve a part, you have to open it, and in the CAD world that is surprisingly hard. Someone sends a file from a program you don't own. A supplier asks for a format you can't produce. A part saved in this year's software won't open in last year's. The usual answers are a costly licence, a clunky download, or uploading your design to a site with no idea where it ends up.
So the file problem became the front door. MeshWeave grew into a place where you drop in almost any 3D file and get back the one you need, in your browser, with nothing to install, and where files are handled privately and deleted rather than kept or reused.
The original ideas haven't gone anywhere. Tools for making parts lighter and checking they're strong enough are being built on the same foundation, for the moment when opening a file is no longer the hard part.
