Hello everyone,

My name is Duy from Vietnam. I am a new user of Dynamo programming.

I have some issue that need your help. How we can seclect Rebar category from Revit to Dynamo??
Please see attached picture to refer for this subject.

My purpose is that I want to find out the minimum distance between these rebars and compare with my expected tolerance (25mm). If they are not comfortable (clashes) with this tolerance, I hope to able to set up a rule that can move clashes in order to comfort expected tolerance.

I would like to hear your advice on this subject. I really appreciate if get any feedback from all of you.

Thank you.

hi @Duy.Le

I tried many options to read the rebar geometry but what I concluded is that we cannot read it because rebars in revit are generated in a different way than other elements,

the solution for that is to get the rebar centrelines using the “BIM4Struct” package using the node “RebarGetCenterlineCurve” see the image below
