The latest version of Yeti enables the creation of custom objects. Geometry wrapped with a '---' and '...' makes an object. Instances of objects are created like any other geometry, with the parameters being all the properties marked with a '!'. Any change to the object is reflected in the instances of the object.
This is still an early version of objects, so things like formulas don't work with them yet. The latest version of Yeti can now be downloaded from yeti3d.com
