hi everyone

In my design i have hot and cold water system i gave a color for cold water supply pipe and another color for hot water supply pipe ,but the color of fitting is still the same in both system as in the pic attached

@taha_ahmed_a  - even if you want this job to be done automatically I think you have 2 solutions. 

1. Have 2 set of fittings in the project (1for cold and 1 for hot water) with your preferred colors and for each system set routing preferences for your desired fitting. 

2. Have 1 set of fittings in the project, have material parameter on instance to be able to change it.

Hi @taha_ahmed_a, 

Here is a LINK to a post which runs through a couple of scenarios. Screencast also added below.

Just to explain, looking at your main problem, which happens when you want to "render" piping in such a way to depict each system type in a different colour.  I can see that you already created different pipe types with unique pipe segments associated to each. This will only control the pipe runs to display in different colours when rendering a view. As @Secttor mentioned, you are left with two main options in this case. [1] create pipe fittings, per system, according to the pipe segment material, or [2] which is the quicker, less maintenance intensive route. 

Just to add to that route. Create a shared instance parameter which drives the material from the family. Remember to add the same parameter to your project and to the pipe fitting category. Then, create a schedule, which can be used to easily assign the correct material to fittings in bulk. Or, create a Dynamo script which takes care of this which is based on the condition that <IF> System Type = A, <THEN> Set Fitting Material to A (brief sample of what can be done).

Just to run through what needs to happen in the family again.

Hope this helps!
