Hello, I have installed Revit before 4 days and I'm starting to investigate it.Till now we haven't use Revit in our office because we didn't need to,but now we have to.We have a house that is architectual project and we want to create the HVAC system. My question is : We have the project in revit file,but when we start to draw something we don't have the ducts,the pipes,the mechanical equipment from the samples.From where we can load them??? I know how to load families and dowloaded blocks but we need the ducts and pipes from the sample project. Thank in advance.

I don't understand what you siad,so i can't help you .No discord, no concord.

My question is: How I can load the families from the samples,because when I start a new project,I can not use them in the project,they are not loaded.I have to load them from a library or somewhere else.

From what I understand from your post, it seems that you have a revit archi model and now you wnat to create a hvac system. What you need is revit mep (same version of as yor archi model). The installer comes with out-of-the-box revit mep families that you can use.
