Grasshopper Python - Sum point coordinates

I got a generator item instead of a value. Do you know how I can get the dimX in my script?

Thanks in advance for your response.

Please don’t start a new thread for every sub-problem. This is clearly related to your other threads.

That said, I can’t tell what you’re trying to do here. Isn’t this still related to getting the center of a bounding box?

I think I figured it out, thank you.

bb_dimX = bb_maxPt.X - bb_minPt.X
