Duct Fitting Visibility

[Anonymous]

Does anyone know why this fitting won't show up no matter how I set view range.

First image shows fitting selected, so it's blue coloured. Second image show how it looks like in a floor plan. The fitting protrudes through the floor slab at an angle. Part of it that is above level is visible, but lower part isn't, no matter how I set bottom range level or view depth. Other elements do show up as they should when bottom view range is set downwards, it's just this part that don't show up whatever I do with view range.

It would help a lot if you posted the file.

BTW, I was taught to never put fittings at a penetration or penetrate at an angle.

Here it is, the problem is visible on floor plan level 2.

Yes, there is general rule of trade to make protrusion perpendicular to opening plane, but that's arbitrary rule, which is formal, and there are circumstances, particularly in ducting, where, for instance, ventilation system plant room is tightly occupied by equipment and nilder-angle offsets are made to avoid concentration of sharp-angled fittings on mains, particularly near fan inlet or outlet, and that rule is substantial for low-pressure ventilation.

Yeah, perpendicular penetrations is not an arbitrary rule. If the penetration is through a load bearing floor, it is advisable and maybe critical to keep the holes as small as possible. 

Your view discipline is set to coordination. Set it to mechanical and the entire fitting shows.

Yes, but it looks as if there is no way to present it as-is, cutting floor plane at some point, showing lower part as an underlay, to present what is actually going on, like with stairs? It looks like MEP elements cannot be presented in such a manner?

If this is a one off type of thing or minimal instances of the condition, I would use the lines overwrite tool or just fill in the blanks with linework.

I have  a similar problem a lot. and it applies in areas where I'm trying to show the ductwork because there is no ceiling. I can see the elbow ducts but not the straight ones.
