Astra

New

Turn a floor plan or a photo into an editable 3D model.

Reads a floor plan, a photo, a render, a sketch or an elevation and builds a clean, editable 3D model with walls, openings, furniture, roof and site, revisable from its stored reading.

  • From a floor plan or photo to a 3D model
  • Clean, editable walls and openings
  • Revise it without starting over

How it works

How to use it

Astra is one choice in the model menu of every app that runs on it.

  1. 01

    Open Floor Plan to 3D Model or Image to 3D Model

    Add a floor plan, a photo of a building, a render, a sketch or an elevation.

  2. 02

    Let Astra read the drawing

    It works out walls, openings, furniture, roof and site, and builds the model from that reading. This takes a few minutes.

  3. 03

    Check it in the viewer and revise

    Orbit the model, spot anything it misread and ask for a correction instead of starting over.

Ideas for your work

What people get out of Astra, by the kind of work they do.

  • Rendair for Architects

    A 3D base from a 2D plan

    Turn an existing plan into a 3D model in minutes, then render views from it for an early design review.

  • Rendair for Interior Designers

    Explain the layout in 3D

    Show clients a furnished 3D version of a plan so they understand scale and flow before you render.

  • Rendair for Builders

    Quick massing for a plot

    Build a 3D model from a sketch or a photo of a similar building to discuss options with buyers.

What it is good at

Astra reads a floor plan, a photo, a render, a sketch or an elevation and builds a clean 3D model from it, with walls, openings, furniture, roof and site. It keeps its reading of your input, so you can ask for corrections instead of starting from scratch.

When to pick it

  • You have a 2D plan and want a 3D model to look at or render from.
  • You want an editable model, not just a picture of one.
  • You need to explain a layout in three dimensions quickly.

What to watch for

  • Clear inputs give better models. A clean plan with readable walls and openings works best.
  • It takes several minutes and costs more than an image, so check your input first.
  • For a quick 3D object from a single picture, Trellis is faster and cheaper.
