Great software, you can't go wrong with Revit
Helps us do much of our work more efficiently and with a professional end-product. The client is very often impressed.
Pros
Very powerful, user-friendly, versatile, professional end-product. If a feature isn't built-in you will still find many ways to achieve the result you want. With a centralised model a change to the model is simultaneously updated in other affected views. Simplifies many tasks which can be tedious in regular CAD packages, for example: dimensioning. Multiple monitor support, in at least the 2 latest versions of the software. Being able to presenting a client with easily interpreted 3D and perspective views. Excellent local resellers and support. Regular updates and patches, and a completely new version released annually.
Cons
Being as powerful as it is it can be buggy at times, but issues are usually resolved easily. Annual updates can also be a negative as files/projects cannot be rolled back to be compatible with previous versions of the software. Quite expensive.
