Three gestures

The same project, from footprint to file set.

Footprint

The rectangle on the ground and the levels. The 12 × 8 m hangar is the trial project of the Free account.

Frame

Purlins, ridge, rafters, posts: a bar model with parametric joinery, in 3D, in the browser.

File set

Dimensioned drawings, cutting sheets, cut list. The workshop file set is exported from the project.

What Carpenter is not

  • Not a structural calculator nor a certificate.
  • A tool to help with design and the workshop file set, in beta: exports stay marked as drafts until the project is validated.
  • The 3D studio is made for a desktop or laptop computer.
