Elefront - visualarq

Hi Francesc,
I am trying to do thing like in this video below, when everything is parametric inside grasshopper and all objects are the real things not a grasshopper prebaked object. But i find out that when connecting to visualarq grasshopper elefront wont delete
the previous existing object. FYI I am relatively new in grasshopper and visualarq. Would you like to help me to do the thing in the video below?

My workflow goal is like the video link below, when BIM objects has a tight relationship with grasshopper(alghorithm design) and has a live update(elefront plugin).

Second, is that possible to create annotation like dimension, smart title blocks elements, so we can create fully parametric construction document?
