Best Practice Phasing Issue

[Patrick]

Looking for the best practices for demo of existing window in demo phase and creating a new window in new const phase. I can demo the existing window but cannot put a new window in its place?

You can get a new window in its' place. To do this simply place a window near where the new wall section is created and align the edge of the new window to the edge of the new wall. If you need it centered and the window is bigger than the new wall chunk use the move command and grab the mid point of the new window and move it to the mid point of the new wall section. The best idea is to not try to place it in the desired location from the start but to align or move it after it is placed to where you want it. So it should be off to the side of the new wall chunk a tiny bit.

There should not be any problem. Check if the views' phase and filter settings are set up properly. There is an illustration showing a recommended setup at this reply of mine in another thread with a related issue:

Patrick;
You make me a little nervous when you say "demo phase".
You don't have an actual Revit Phase called Demo, do you?

Typically, you should have an Existing Phase and a New Construction Phase, but not a Demo.
You only have two Phases, but you have three Views (Existing, Demolition, New)

• Existing has its Phase set to Existing and Phase Filter set to Previous + New
• Demolition has its Phase set to New and Phase Filter set to Previous + Demo
• New has its Phase set to New and Phase Filter set to Previous + New

You document the existing building in the Existing View
You Demolish things in New or Demolition - whichever you prefer.

Your Demolition Sheet has the Demolition View
You New Sheet has the New View

My method is a bit more tedious, but i prefer it for the way it handles the situation. I will actually copy/paste-alligned-same-place the entire wall, but then edit the profile of the duplicate wall so it is ONLY the size of the window to be demolished, and i will make sure the window is hosted on THAT wall, and not the main wall. Then, i demolish the wall, and the window goes with it. It lets me better control the actual extents of what is being demolished (which may or may not coincide with actual size of the window in real life... i like to have one method for all circumstances, for consistancy). I never liked that Revit assumes a demolished object with opening is automatically infilled, it is rarely the case. This way prevents that.

Ive done EXTENSIVE renovation work with it. It doesnt even take that long once you are used to doing it.

When doing so i just get a bug when ever i try to join walls together in the demolition phase with sometime recursive holes down to the existing phase. I use some nested family opening like your doors. And i have three phases (existing, demo, and project)

Imagine you have a "to be demolished" wall hosting a window surrounded by 4 existing wall that stay undemolished. When having this build your to be demolished wall is not merged anymore with other walls as it should be. Then the reflex is to join it to the other walls. until here everything is just fine.
You create a new wall hosting a new window in the new phase. again you get your new wall that is not merging with the existing walls that were not demolished and who were joined to the demolished one. Again you have the reflex to join your new wall to the existing one and BAM.... here starts some strange behaviours. Your intermediate demolition phase shows the partial infill (looks like the bolean of previous and new opening) floating in the frame that was demolished.
Other problem comes from my nested sill that has a yes no parameter. When you activate it on the new window for whatever reason the void that comes with becomes visible in existing phase. I'm actually experiencing massive problems with nested families. (will talk you later about windows and in place walls).

Did you experienced such problems and found any trick to get rid of it?

[cyberjuls]

Ok i'm getting it slowly.

My window families contains a nested sill and a nested roller shutter that both contains a void and that are activated by a yes/no instance parameter. By the way both belongs to window family type. It seems that this void is generating a lot of problems. I'm testing it right now but looks like i should better go for just one void in the frame family thus having to get different families when having a concrete sill or a roller shutter or none. If anyone has some feedback...

If anyone has some feedback...

Better post you window family then.
