BUILT FOR THE WAY YOU THINK
Familiar tools.
A natural creative flow.
Draw, organize, express and extend.
The right tools for every step of modeling.
01 / MODELINGDraw a profile.
Draw a profile.
Give it depth.
Start with lines, rectangles and circles, then turn faces into solids with Push/Pull. Endpoint, midpoint and intersection snapping work with axis locking and numeric input to keep your ideas precise.
Turn ideas into geometryAvailable tools
R
Start with a profile
Lines, rectangles, circles, polygons and arcs.
P
Build volume
Extrude along a face normal, with set distances and repeat operations.
M
Refine the form
Move, rotate, scale, copy and create arrays.
A SIMPLE PATH TO THREE DIMENSIONS
One idea. Three steps.
Build, organize, then express.
Take your design from simple solids to a complete model.
Organize & reuse
Organize geometry into groups and components. Edit nested content and reuse definitions to keep repeated elements consistent.
ORGANIZE & REUSEStyle & present
Set materials, edge styles and shadows. Explore spaces with scenes and sections, and add text or 3D lettering.

A FEW THINGS TO KNOW
A few useful answers.
Is the software free to use?+
Yes. ModraUp is free to use on macOS, Windows and Linux. The source code is not currently public.
Can I download it now?+
The project is in development. A public download channel and release date have not yet been announced. This page showcases current features and does not provide an installer.
Is ModraUp open source?+
The source code is not currently public. Any plans to open the source will be announced separately.
Does it support SketchUp model files?+
OpenSKP enables .skp import and export; the native project format is .osk3d. SKP exchange does not cover every feature: models containing section entities must be saved as .osk3d, and model and scene shadow settings do not fully round-trip through SKP.
Can existing Ruby plugins run directly?+
The project is implementing a Ruby API with names matching SketchUp, including extension loading, a Ruby console, toolbars and HTML extension interfaces. API coverage and behavior are incomplete, so plugins need individual testing. Full compatibility is not guaranteed.
Where do these screenshots come from?+
These six screenshots were captured from ModraUp on macOS. They show house shadows, scripted 3D text, section planes, a large terrain model, and two views of a large outdoor commercial building model. The model tests reflect specific scenes and do not represent performance for every model.
