Offsetting polygons

Offsetting polygons

- [Narrator] I have my exercise file already. So, the standard off setting, in Rhino and in Grasshopper, the offset curve command, is a powerful tool, because it lets you offset complex nerbs curves, and it calculates precise offsets for these potentially complicated pieces of geometry. But if you're offsetting polygons, like this, you really don't need all of that horsepower in the component. You can see this is taking 21 milliseconds to compute, which is not a lot of time but, if you had a lot of curves it would make a difference. So, as an alternative, we have the offset loose component, which does a similar offset, but it takes a lot less computation to actually calculate the offest curve, because all it's doing is it's offsetting at the control points. So, if I were offsetting a complex nerbs curve here, that offset wouldn't be consistent along the entire length of the curve, it would really just be doing the offsets…
