It was a nightmare if we need to do the Section View that containing multiple disciplines underground utilities and most of the network contain large number of pipes when using data shortcuts. I have some bad experience that I only need few pipes from each network (20+ Networks and some of the networks contain over 100K pipes.) for section view, but I need to reference the whole network to produce the section view via data shortcuts and with the result, I need to take over 1.5 hour to open the dwg file of the section views and I have already turn all the components display off for plan and model view but still got a very slow performance when working on this file.
