ZomeCAD

Written in C++, ZomeCAD is an interactive 3D modeling tool you can use to view and design Zome System models. It's mainly geared toward experienced users and can export projects as JPEG, PNG, TIFF or BMP graphics files. Several advanced options are available.

After a speedy and simple installation, you're welcomed by a user-friendly interface, where you can put together Zome System models using hubs and struts.

Hubs are represented by white spheres that you can attach multiple struts to. They are resizable and come in blue, red, yellow, green, orange and purple. Each hub can be linked to 12 red, 20 yellow, 30 blue, 60 green, 60 orange or 60 purple struts.

It's possible to customize the background with cuboctahedral and icosidodecahedral symmetry by applying blue, yellow, green and any other colors for poles and equators. Moreover, you can increase or decrease the symmetry mirroring, rotation, tessellation, or scaling.

ZomeCAD can be instructed to automatically add hubs to new struts whenever this is necessary. You can toggle between perspective and orthogonal projection mode, view the inventory with all model parts, undo and redo actions, save the model to file and resume work later, as well as hide the main, replay or status bar.

As expected, ZomeCAD remained light on system resources usage in our tests. It supports keyboard shortcuts and includes a help manual for view and edit options, along with strut operations. It permits more than 100,000 parts for models.

To sum it up, this software application comes equipped with handy options and configuration settings for creating and exporting Zome System models. Unfortunately, it hasn't been updated for a long time and the product seems to be discontinued.
