Made for Engineering Education
Engineering students & educators: from drawing to print, in class
Drafting, 3D printing and GIS courses: view DXF/STEP/IFC, repair meshes, slice, make vectors and documents — no install.
No install or license; works in the lab or on a laptop browser
Drawings, models and point clouds are viewable without upload
Local tools include a daily free allowance, enough for coursework
Drawings and models
View DXF/STEP/IFC and 3D models to teach structure and assembly.
DXF Viewer with LayersLocalOpen DXF files in your browser: layer show/hide and recolor, distance, angle and area measurement with snapping, SVG export — free, no upload, no sign-up.STEP File ViewerLocalOpen STEP/STP files (AP203/AP214/AP242) in your browser: measure, section, explode and screenshot. Parsed locally (OCCT WASM), no upload. Free, no sign-up.IFC Model ViewerLocalOpen and check IFC models in your browser — measure, section, element tree, takeoff CSV, 2D plan. Parse errors show on load. Free, no upload, no sign-up.3D Model ViewerLocalOpen STL, OBJ, PLY, 3MF, GLB and glTF models in your browser — measure, annotate, section and screenshot. Free, no sign-in, no upload; all rendering is local.
Print and make
Repair meshes, scale and slice-preview to turn homework into objects.
Mesh Doctor for STLLocalCheck STL/OBJ/PLY/3MF/GLB for holes, non-manifold edges, degenerate faces, watertightness; defects marked in viewport; weld-repair, export STL. Free, no upload.Scale & Resize STL FilesLocalScale or resize STL/OBJ/PLY/3MF/GLB by a factor or per axis — mm↔inch presets (×25.4), before/after bounding-box check, STL export. Free in browser, no upload.STL SlicerLocalSTL slicer online — slice meshes by layer height, preview each layer contour, export layered SVG or outline G-code. No upload; Pro.Center STL on the BedLocalCenter an STL on the build bed, drop it to Z=0, scale to an exact target height and export print-ready STL — local in your browser, free, no upload.
Images and documents
Bitmap to vector, OCR and PDF handling for course material.
Image to SVG ConverterLocalConvert images to SVG — trace logos, line art and icons into scalable vectors with an adjustable color count. Free, in your browser; no upload, no sign-in.Image OCR Text ExtractorLocalExtract text from images with OCR online — combine any of 20 languages, no upload: it runs in your browser. Free, no sign-up.Merge PDF Files & Combine into OneHybridMerge PDF files in your browser — remove or rotate pages, drag to reorder pages; bookmarks point to the right pages. Free, no sign-in, no upload under 10 MB.Compress PDF Files & Reduce SizeHybridCompress PDF files in your browser — Light keeps text selectable, stronger levels re-encode images for a smaller size. Free, no sign-in, no upload under 10 MB.
Code and data
Parametric modeling and DXF/GIS data conversion for programming classes.
JSCAD Parametric ModelingLocalCode parametric 3D models in JavaScript, tune them in a form panel and export print-ready STL — a free online OpenSCAD alternative. No upload, no sign-in.DXF to JSON ConverterLocalParse DXF into structured JSON — entities, tables, blocks — for development, debugging or data pipelines. Free, no sign-up; nothing uploaded.CSV to GeoJSON ConverterLocalConvert CSV with lat/lon columns to GeoJSON points in your browser — free, no sign-up, nothing uploaded. Columns auto-detected, map preview.GeoJSON Map EditorLocalEdit GeoJSON on an interactive map — draw points, lines and polygons, edit attributes, undo/redo, then export. Free in your browser, nothing uploaded.
Whole-class assignments and project weeks
The local daily free allowance covers most coursework; when batch or cloud processing is needed, Pro is $15/mo and students can try it first.
