Splitting a Topo

Is it popssible to split a topo on mass?

I have had a look around and cant seem to find anything

here is my idea…

Model lines that make up all you different splits and then your topo. it then cuts your topo from where the model lines are placed?


What are your thoughts …







You can split a topo directly in Revit (Modify Site -> Split Surface), but it is not clear to me what you mean by “topo on mass”?


sorry for only just getting back to you It didn’t send me an email.


I will try to explain again.


I have series model lines that are a guide to splitting my topo. the manual process is how you have mentioned however the topo needs splitting about 100 times so im trying to create an automated version of this.


Any ideas?
