Grasshopper - Archicad Live Connection | Points query

Josh Verran — Wed, 07 Jun 2023 01:26:40 GMT

I'm not sure if I have the right forum here (or even if this should maybe be posted on the Rhino - Grasshopper forum).

I'm having a bit of trouble with "points", in particular adding nodes that require point data as the input, but getting notifications advising that the data doesn't contain points.

I feel like I haven't worded that well, so perhaps this image will clarify.

There is a node called "Construct Point", which is being used successfully to place columns (anchor point).

Want to use those same points to create a curve/line, but getting notifications that no points are being found.

I'm only just starting on Grasshopper, so still have much learning to do.

Hi Josh,

It looks like something is wrong with your Data Tree. Try to flatten the point output.

Thanks Gino

I'll do a search on what Flatten is, I have seen that on the right click, I don't suppose you could describe what that does?

Hi Josh,

a short Info about this you can find here:

There are also a lot of Tutorials regarding the topic "Data Tree". I'm not an Expert yet, but some knowledge of this is very important before starting advanced scripting.
