algorithmic modeling for Rhino

extracting x,y,z coordinates from a point

can anyone direct me to a tutorial, or explain how I would go about extracting the x,y,and z coordinates of point.

I want to set up a logic based on the Z coordinate...is this even possible?

Specifically, I'm trying to create a definition that will allow me to move a series of planes different amounts in the x or y direction, based on there heights [z].

So for example if the plane is 3' high or less it will move only 1' in the x and/or y direction
if the plane is between 3'-5' then it will move 2' in the x and/or y direction
if the plane is between 5'-10' it will move 3' in the x and/or y direction

thoughts?

Hi Ryan,

you can do this in two basic ways:

1) Use the Decompose Point component (icon contains three arrows moving from a point to "x", "y" and "z" letters)

2) Use an expression component with the following expression (assuming you named the input "pt"):

pt.z

Hi Ryan,

Have a look at the enclosed definition, It moves planes as per the example you gave.

Cheers
