Is there a way to add model elements in a 3D view to a displacement set with Dynamo?

Amazing! I noticed that it worked when selecting multiple elements, but not when selecting only a single element to displace. When only a single model element is selected it gives this error “Error: iteration over non-sequence” Is this a limitation with displacing?

you could try a list create before feed in if single, or create a node so you have option for lacing…or edit the code for both single and multiple

Great. Thankyou for your help

Hi sovitek,

I am currently trying to adapt this script to allow for multiple views, elements and vectors.

I have 10 walls, and I want to explode each one in 10 different views based on the wall orientation of each wall for the vector direction.

I am trying to do this through mapping my lists, but am having no luck. Is this something I could do through mapping the data, or would I need to understand python and adapt the script itself.

Thankyou

I think that the easiest way will be to create a custom node from the Python node, and leverage list lacing and levels to accomplish what you are after.

Hi,
Here’s some Python code:
A wall, a movement game applied to this wall, a 3D view created and centered on it.
This could be a working basis.
