Phasing Work Flow - Editing elements from previous phases

What is the work flow for editing elements created in an existing phase while working in the new construction phase?  Othere than graded surfaces that handle this rather nicely, I have never seen a session/video on how to handle this with basic components.  For example, an existing building with a simple existing roof needs to be modified to add a second level during the New Construction phase. When you edit that roof in the new construction phase, the edits are also reflected in any of the previous existing views and all of the existing phase drawings are no longer accurrate.  The only way I have made this work is to make a copy of the existing roof and insert it on top of itself in the new construction phase.  I then demolish the entire existing roof in the new construction phase.  I then edit the copy as needed but it now indicates it is part of the new construction phase.  But in fact it is not new construction, rather it is still a piece of the existing building.  Is there a better, more sophisticated way to undertake this rather typical exercise?

Split the existing roof into pieces: existing to remain and existing to be demolished.

Ok, thanks! Simple enough and I seem to be able to heal (join) the two
parts in the existing view so you don't see the line between the two parts.
This seems to work for the structural beams that I have modelled in the
existing structure.

Now, how about cutting an opening though/into an existing floor in order to
insert a new stair. It seems that the opening created in the new
construction phase also shows up in the existing phase views? It seems that
the opening, while created in the new construction phase, gets assigned to
the existing floor. How do you handle this?

Create opening as a family and place it in he new construction phase to cut existing roof. Shafts, vertical cut opening, opening by face, and in place voids won't work with phasing.

And the family can be phase specific? Cutting only what I tell it to cut?
You are referring to a void family?

A face based family with a void, or a roof/floor based family with a void or a cutie opening, similar to a door or a window family.

In all my years of REVITing I have never tried something like this. My
families are often incredibly complex and parametric, but a simple family
with an easily modified void opening would in fact be quick and easy, and
at least as easy as making multiple copies of the floor and
remembering which copy has openings in which phase. Something to try on
Sunday! Thanks

If you're modeling both new and existing, sometimes it's just plain easier to Phase backwards. That is, build the finished product first and then "add on" the existing and demo portions.  

 

FWIW

 

P.S. Roofs are always a b*tch.  That's why God invented beer.   :zwinkerndes_Gesicht:
