Lovcad

AI text to CAD: describe a part in plain words and get a parametric model with real dimensions

Lovcad is a freemium browser tool for functional parts with real dimensions, such as brackets and housings. New accounts get 100 permanent credits after email verification. Plans: Starter $20/month (2,000 credits), Pro $50, Studio $80, Max $120; one-time packs from $25 for 2,000 credits. Credits pay for AI requests, not a fixed number of models. Exports STEP, STL, 3MF, OBJ, GLB and SVG. Last checked .

What is Lovcad?

Lovcad is an AI text to CAD tool in the browser. You describe a part in everyday words, such as a bracket, a flange, a housing or a gear, and an AI agent writes the model. When a key dimension is missing it asks first, and after each build it checks several views against your request. The result is a parametric model in millimeters: hole count, thickness and diameter become sliders that rebuild the part in the browser without a new AI request.

There are two modeling modes. Mechanical part uses exact-surface modeling, so holes, fillets and threaded holes are true geometry and the STEP export can be edited further in SolidWorks or Fusion. Geometric shape uses boolean and mesh modeling for lattices, cut-outs and sculptural printed parts. You can attach up to four sketches or photos or a PDF drawing, start from an existing STEP file, make engineering drawings (PDF, DXF or SVG) and run manufacturing checks for FDM printing, CNC and injection molding.

Exports include STEP, STL, 3MF, OBJ, GLB, DXF and SKP. A new account gets 100 permanent credits after email verification; after that it runs on paid plans from $20 a month or one-time credit packs from $25. As with any AI CAD tool, check the dimensions and fits before you print.

What you can make

  • Brackets, flanges and housings
  • Gears and multi-part assemblies
  • Parametric parts with exact STEP
  • Lattices and sculptural printed parts

How to use Lovcad

  1. Sign up and verify your email to get the free credits
  2. Pick Mechanical part or Geometric shape and describe the part with its sizes
  3. Answer the agent's questions and adjust the parameter sliders
  4. Export STL or 3MF for your slicer, or STEP for a CAD program

Lovcad pros

  • Parametric results: dimensions become sliders you can change without a new AI request
  • Exact-surface STEP for mechanical parts, so you can keep working in CAD
  • Asks about missing dimensions and checks its own build against your request

Lovcad cons

  • Needs an account, and the free credits are a one-time start
  • Credits pay per AI request, so the cost of one part is hard to predict
  • AI output can contain dimensional errors, so every part needs checking
