Revit Phasing in a renovation project

Recently I was involved to assist in a renovation project which makes use of phasing in Revit. Wow, I thought this is my chance to use the theoretical knowledge about phasing which I've learned 5 years ago from a Revit/CAD guru associate. At that time, he warned me about the pitfalls of using phasing in the Revit world and if I recalled correctly, he advised to use it carefully by deciding how many phases you need and define it within the "Phasing" control tab panel. This is an important step in phasing within Revit. Secondly, set up each individual view to reflect what you wish to show. While modeling the building, ensure that you are in the correct view which corresponds with the phase you are after too.

Going back to the renovation project that I am talking about, I dogged into the project file and the first thing that I noticed was, it deviates from the normal standard phasing method. The earlier team involved made use of the "filter" in Visibity Graphics Tab to control each phase view. Sadly to say, I thought to myself, this will create a big headache for the one who will continue the project. Sub phase and step code were introduced in the Phase attributes for each element (in Phasing-Phase Created Parameter). Just wondering why they did it. In the Phase tab the filter is already there waiting to be modified or use it out of the box.

Reorganizing the whole phasing will be a very painful task and I have a weekend to think it over.

Height/Depth of Walls

When you create a wall (an architectural wall or a structural wall), you can specify the following properties on the Options Bar:

- Level (for 3D views)
- Depth/Height
- Top Constraint
- Unconnected Height

Together with Base Constraint, these properties control whether the wall is drawn from a specified level upwards or downwards, the height of the wall, and whether its height will change when its base constraint or top constraint moves.

When you create a wall in a plan view, the Base Constraint is the level associated with the view. When you create a wall in a 3D view, use Level on the Options Bar to specify the level to use for the wall's Base Constraint value.

Note: When you use Depth on the Options Bar, use a structural plan to see the walls extending downward from the current level, or modify the view range of a floor plan to make them visible.
