What is the point of the sketch tool?

Hi! I just started my first job in architecture and I’m learning Rhino/Grasshopper for funsies to help with concept iteration and high quality renderings.

I’ve been going through a ton of tutorials and forums and I’ve been a little confused about the sketch tool. I cant seem to figure why someone would want to use it? I feel like it has some hidden potential and I just haven’t found it yet.

Hi

I would say that the hidden potential is that you can quickly draw something that either illustrates the purpose of the definition or, e.g. puts a rectangle around a number of components (instead of using group). The sketch tool is very limited in Grasshopper but you then send that sketch to Rhino where you use the Rhino drawing tools to make it right and then send that Rhino sketch back to Grasshopper.
