MEP library improvement

[Nico Heinz]

I think we need a big update in the MEP library. No new objects since ..... I can't even remember

They can be pretty basic, but I miss a lot of 

- Valves (f.ex. 3 way valve, etc) with a schematic 2D diagram as an option

- Ventilation and Aircon equipment and units. (f.ex. VRV outdoor unit, ceiling units, 4 way ceiling unit,...)

Same applies for lights... a little update would be fantastic.

We need better 2d documentation for MEP elements too. A symbol label for the slope is missing (arrow pointing in the slope direction). The only possibility for now is showing it ON-SCREEN  only, and cannot print it.

Agreed. I have raised this with someone directly at Graphisoft and have seen/tested a UKI library preview with a rotary isolator and a few minor items. But I always end up using a cube for so many MEP items that I can't use an archicad library part or get from manufacturers.
