Never let Tridium Niagara standard graphic libraries limit your project goals
Having worked with Tridium Niagara for about 10 years and using their standard graphic libraries, it can be said that sometimes you have to break out the tools and create your own custom elements.
For this customer, we had to create an Adiabatic Cooling Coil, which is not something you come across every day. With two custom SVG graphics added, the standard N4 SVG library works well in this instance. Many additional items still need to be created.
Update May 2020: back in 2017, we were using Sketch for SVG work, but having discovered the functionality of Affinity Designer, creating new graphics and making modifications to the library graphics, has got a lot easier.
