Hello!
I’ve made a dynamo script which creates boundary lines for a building footprint, at a user-specified height and offset from the selected level and from the walls of the building too. Currently, the script runs okay, but I think it can be improved and optimized in a much better way. If you have the time, feel free to go through the script and let me know if it can be shortened, or made more efficient.
Since its a script that only creates model lines, it runs quickly, but still, i think the number of nodes can be minimized.
Any pointers would be appreciated.
