(Question) Simplify my clusters on Grasshopper

[kimkyung83]

Hi, I did extrude curves by grasshopper. Then I created this by cluster to make many curves at same time.
However if I select multiples curves and connect to my cluster, ‘Devide solid’ doesn’t work which means, it cover inside of dome. (photo)

So that I connect eacy curve to each cluster ;;;;;;;
Can I simpify these stuff?

Hi.
There are a few things I’d like to recommend you to do in this kind of work.

1. Boolean operations are usually computationally very expensive. Avoid if possible when if you are doing multiple operations.
2. Work as close as possible to the origin and use m unit rather than mm.
   then, the amount of calculation will be greatly reduced.

Hey,
THank you for the good tip about boolean and unit.
and your file.

Best regard, KIM

Work as close as possible to the origin and use m unit rather than mm.

I was wondering, why is that? Why would m be “lighter” than mm?
Why working close to origin?

Why would m be “lighter” than mm?

When if you are dealing with large amount of geometries or numbers … but If you have enough memory, then it might not be an issue.

The pain with models far away from the origin

Hi everyone, Rhino looses precision when the model is modeled far away from the global origin. (Due to calculation tolerances, I believe) In architectural projects, it often happens that the origin of a building model is far away from global (0,0,0). When exchanging models with other project parties it is essential to have the same reference origin and unit system. So we are not “free” to define the origin of our model. Currently we are using the approach to transform all necessary model obje…
