Hello again. I have just finished my duct population and from the top view it looks way too uniform, but from the human mannequin point of view it looks fine. Should I delete it and start over or is uniformity fine for this part of the model?
In reality duct work is pretty uniform in layout. What I would suggest you look out for is the duplication of the pieces. In the view with mannequin, the two horizontal ducts are the same, swap over one or two of the blue with the purple to mix it up a bit.
The overall layout it will depend on your final render view.
Right, so I've reworked it a bit. I think this looks a lot more varied.
I'd say it's worth looking up your own references at this point. There is no right or wrong placement, just place them based on your overall vision dependant on the views/renders you expect to make. In references I checked often the ducts/pipes tend to follow the edges of the carpark and the center of the ceiling and columns are relatively devoid of accessories
