Creation of a particular form

[Anonymous]

Hi all, I'm having some trouble creating a desired massing for a building in revit. 

The sort of shape I want to create takes inspiration from the MAAT building in Lisbon (attached) with a sloping sort of building with a cantilevered front that provides protection to the access points, I have tried to model the building so far and have got close-ish but haven't been able to replicate a sloping building without getting some sort of error whilst massing.

What is my best way to model this, and can I have some form of mini-tutorial to help me get this done?

I have attached three items, the building with inspiration, the closest attempt massing I have achieved and the form of the building in the third attachment. 

Thanks for the help!

Imagine cutting that building at 3 different level - Ground Level, approx. 2100mm high and Roof/Ceiling level.

Now create a Mass, draw 3 closed reference lines at those levels, select them and Cerate Form, then create walls by face...

I've attempted this before, but have got countless errors when trying to do so, frustratingly.

Just with even trying with two floors, it won't create the shape I want.

My preferred method in making such forms, is to use Masses as follows :

• create an extruded form based on splines , then use interactive modelling adding Profiles, change their scales and shapes, moving  them and Edit in Sketch Mode and  at the subobject level ( moving Reference Points that belong to a selected Profile)
• after I am pleased with the result , I load the Mass into the Project and use Wall by Face and Roof by Face( for horizontal surfaces.

In my screencast I've shown only the Mass Modeling:
