ForgeShape finds open edges, bad normals and thin walls before slicing, then exports STL/3MF — all on device. A print fails and the model still looks fine on screen. ForgeShape opens STL, STEP, IGES, OBJ, GLB and 3MF models on your device, finds what blocks printing — open edges, wrong normals, thin walls, overhangs — repairs it, and exports STL or 3MF for your slicer. It also converts between CAD and mesh formats. Nothing is ever uploaded. Key features: - Import STEP (.step/.stp), IGES (.iges/.igs), STL, OBJ, binary GLB and 3MF models, all parsed on device - Automatic detection: open edges, non-manifold edges, self-intersection (up to 500k triangles), surface orientation, duplicate faces, degenerate triangles, wall thickness, overhang, units and size - Each body is classified as a solid candidate or an open shell; closed manifold models report a measured volume - Guided repairs: weld and stitch boundaries, fix surface orientation, remove duplicate faces, fill small holes, remove degenerate triangles, or run them all in sequence - Repairs apply in one step, then show before/after; deep repair previews, escalates tolerance until the model closes and reports how far geometry moved - Pick a finding to highlight the affected edges and faces, or let the camera turn to frame it on the far side of the model - Inspect it your way: shaded, wireframe or both, Y-up and Z-up conventions, focus on any surface point, and level of detail that keeps large meshes responsive - Select a face to measure planar width, height and area, or cylinder radius, in source units - Fit the model to a print-size profile with one uniform scale, then recheck automatically - Three jobs: print to STL or 3MF; convert to OBJ, GLB, STL, 3MF or faceted STEP; Reverse to CAD to STEP - Source colors are read and shown: OBJ materials, 3MF color groups and baked textures, GLB base colors; on export only GLB carries color - Reverse to CAD for meshes: planar, cylindrical, conical and spherical faces become analytic STEP geometry; precise CAD sources are not reversed - Honest reports: every check names its mesh-snapshot evidence and lists what remains unresolved - Export the check as a PDF, HTML or JSON report in four languages, with marked-up model figures and close-ups of located findings For 3D-printing users, engineers converting between STEP/IGES and mesh formats, makers fixing scanned or downloaded models, and teams delivering in multiple formats. Common questions: - Is ForgeShape a slicer? No. It handles the step before slicing — checking and repairing the model — and does not generate G-code. - Can it repair every broken model? No. Issues beyond the supported scope — non-manifold edges, large openings — are labelled as not automatically repairable. Deep repair closes more models, but states how much the shape changed. - Does Reverse to CAD recover the full design? Unrecognized regions stay mesh; the STEP has no feature history and is not guaranteed machinable. - Are models uploaded to a server? Never. Import, checking, repair, measurement and export all happen on device. No account, no cloud, and you choose where files are saved. Pricing & Access - Free: import and view every format, run every check, apply every repair, read every finding, and export the report. - Pro subscription: export and save your model — repaired, converted or reversed to CAD.
