What you can use it for

Online 3D house design

Trace a floor plan or start with the house generator and within minutes you have a 3D model with a roof, windows and dimensions to show your family and your architect.

3D garden and plot design

Enter your plot, place the house and design the terrace, paths, beds, fence or pool. You’ll see where the shade falls and can count materials straight away.

3D interior and kitchen design

Measure the room, place the furniture and walk through it before you buy. You’ll see whether everything fits and how the room feels.

Furniture design and making from a 3D model

From idea to parts: design furniture to exact sizes, count the material and print a board layout for cutting.

3D models for 3D printing

Simple modelling in millimetres and an export your printer accepts without repairs.

3D models of parts and mechanical components

Draw bolts, gears, flanges or electronics enclosures in millimetres and print them straight away or send them to the workshop.

Construction calculators from your 3D model

No retyping sizes into a spreadsheet – select part of the model and the calculator works from its real areas and volumes.

A simple SketchUp alternative

If you miss the simplicity of the old SketchUp, try ModVex: the same way of modelling – draw and pull up – right in your browser.

    The push/pull tool turns a face into a wall, roof or piece of furniture.

  3. Save and export

    Download the project, an image, a floor plan or a file for 3D printing.
