The Rhino 8 WIP provides the ability to create constraints. Constraints are a set of rules such as the length of a line, or angle between two lines, that are added to geometry. These allow you to build complex relationships in your model that are maintained as geometry is being manipulated.
The constraints panel can be accessed from the panels menu or with the
Constraints command. The currently implemented constraints are focused on 2D drawings and the following new commands are available:
Here is a simple introductory video to help you navigate and get acquainted with the new tools.
