VisualARQ curtain wall issue


I have this problem when I try to make a curtain wall on the exterior of my model. It only appears rather one-quarter of an element than the whole curtain wall
The curve I am using is basically a circle. Is it a bug or a mistake from me?
Please advise how to fix it,
Thank you.

Please help…really at this time in the night not sure wheter to do it with paneling tools(makes my model too heavy for my laptop to process)…I already reduced the gasholder’s size from 8 floors to 2(are actually 4 considering the basement) as you can see …and I am running out of time to sort it for my hand in.

Hi @antonia.gregoriana I may require the 3dm file to better understand what’s happening. Please send it to

(Make sure you are using the last version 2.8.4)

Hi Francesc, i have managed to sort that, now have another problem, I have just emailed you.
