ChainTools consists of two commands: ChainTrim and ChainSplit. In ChainTrim you interactively build a set (chain) of trimming curves on an object to be finally trimmed. When picking the curves, you have control of how the trimming chain will look like, which intersections, edges or curves it will include. The command checks and warns if there is no continuity between the curves or to an edge of the trimmed object. It also allow you to extend the curves on the trimmed surface. ChainSplit works similarly, the only difference is that all parts of the splitted object remain.
To use ChainTools commands, simply type "ChainTrim" or "ChainSplit" in the command line. You can also use buttons in a dedicated toolbar that will appear in Rhino when the plug-in is installed.
Now ChainTools is free.
If you appreciate my work (it consists of quite much code!), I will be thankful for your donation :-)
