exact measures of a primitive (?meters by ? meters)

[anicg]

I used the measure node by how can I find out the very precise measures in meters of the primitive (.. meters by .. meters), say for primitive 13 and 11.

For a square it's quite simple. Measure the perimeter and divide it by the number of edges (4) to get the length of each edge. Or measure the area and take the root of that.

It's not as simple for a rectangle, there you could instead use Convert Line SOP. It will convert the edges to a line and give you the length in "restlength".

Here's an example to go along, if it helps.

Thanks. One final step: how to make the size of a box match the measured x,y,z of a bound, not copy pasting values, but linked?

And position. So the idea is to create a box that perfectly matches the size and position of a bound node.

Match Size SOP?

[Sophie]

I'm not sure if you need the length for anything else, but if you want to match the bounds of something else, maybe you can just use a matchsize node

I've attached a very simple example of this
