The Common part is principally related to numbers. As a mathematical calculation. Part divides the overall sum of a set of digits, by the variety of digits.

However I’ll present you the second method of utilizing this part in Grasshopper. Let’s draw some factors in our rhino. Afterwards, we are able to take all these factors and join them to the typical part and on this method, you will get the arithmetic imply of all of those factors. We will say that the results of the Common part with factors as an enter is a gravity centre of all factors.

Okay, however that is simply concept. 

How can we use that in your work?

Let’s go to the instance of roof construction while you take all the breps parts from this construction. We join them to the amount part to search out the centroid. Afterwards, when you will have a lot of centroids of parts, really, we are able to discover the typical of all of those factors in that method, you will get the gravity centre of the entire construction.
