The capabilities of bimsrv are really unique. It is very easy to create BIM models. You can easily model different components of a building using this tool, which has been very helpful for our project managers. I have no dislikes about it thus far. There are some other software that give you more control over your model. But with bimsrv, you don't get all those features. You just get what you need. We use it mainly for construction documents and as-built models in order to show clients exactly what we build.
