Guides & explainers

Plain-English guides to browser-based parametric CAD and 3D printing — the concepts, the file formats, the tool comparisons, and hands-on help to start building.

Guides & explainers

  • What is parametric CAD? — How editable parameters and a recorded history drive a model — and why it matters for 3D printing.
  • STL vs 3MF — What each format stores, when to use each, and how to convert between them free in your browser.
  • How OwlCAD compares — OwlCAD side by side with TinkerCAD, Onshape, Fusion 360, and FreeCAD — browser, free tier, parametric, privacy, export.

Learn by doing

  • Getting started — Place your first shape, combine with booleans, and export a print-ready file — a five-minute tour.
  • Video tutorials — Follow along and build real 3D-printable projects, from a name keychain to a numbered die.
  • Help center — Task-by-task docs for every tool — adding shapes, sketching, modifying, print prep, and exporting.
