THEN ( I don’t know what) ELSE (I should be doing).
Anybody got a good resource on syntax & creating if, then, else operations? I’m thinking I need one to tell grasshopper not to create any band that goes around a corner (possibly where the points are not on the same plane or where they are further apart than a set distance, because it will result in a warped loft). Any links on making a conditional function or any ideas on a better way to preclude these instances?

Hi Jana,
Take a look at this tutorial: http://digitaltoolbox.info/grasshopper-intermediate/conditional-statements/ . Digital Toolbox is a great reference. Watch the tutorial and give it a shot before we meet today.

Jana,
You might also look at the conditional patterning tutorial on this blog. It uses some conditional logic and demonstrates how to work with the results of your [conditional] tests using the dispatch component in GH. Here’s the link:
