Apologies for missing this one live. Work, go figure.
I am watching the posted video, which is a bit fuzzy (and has the Zoom participants blocking the right side of the screen), so I am building a graph of my own to better understand the Live Demo. I imagine the Curtain Wall I created is different from yours, but the graph was cruising along just file up to the Vector.ByTwoPoints node. Your results of that node have varying values for the X and Y components, and 0 for all of the Z component of the vectors. My node has varying values for the X and Z components and 0 for all of the Y components. How did my axes get messed up?
Did I miss setting a vertical work plane or something? Or is Dynamo telling me to stay away from geometry and stick to changing parameter values? ; - )
PS. I am also confused about why the vector needs to be converted to a 2D vector - if all values of one axis are 0, is it not already 2D? Or did you have non-0 Z values for some points, that did not show in the video?
PPS. Thanks again for this ongoing series. I am learning quite a lot from it.
I decided to make my "2D" vectors from my X and Z values (mapped to X and Y, respectively, in the Vector.ByCoordinates node), and ran with it from there. I will note that the distance values that provided were exactly the same as the distance values from the original vectors.
I still would like to know why my original vectors had 0 for the Y values, but the graph still worked when I used my Z values.
(I did not have Jacob's G1 and G2 System Panels in my model, so I used Glazed for True and Solid for False.)
