Greetings again Alan,
Thank you very much for your last reply. I hate to keep harping on this same issue, but I just haven't been able to reslove it yet.
I realize you must be very busy, but if you can spare the time to read and understand my questions, your help will be greatly appreciated.
I reviewed the file you included in your last reply and sure enough you don't seem to have the same problem I am having. There are so many variables that I suppose it's difficult to nail the exact cause down, but after reviewing the file you sent, the only difference I can see between what you did and what I did is that I created a separate phase called "demo" (between "existing" and "new") and I set the window, the well, and pad assembly to be demolished in the "demo" phase.
I see that in your file, you did not create a demo phase, but instead made use of the phase filter system to create veiws showing the demo phase and the new construction. Perhaps I have too many phases and have created some confusion for Revit. Could t his be causing the problem??? I could fold the new construction phase into the demo phase, rename the phase and use phase filters as you did, but I'm reluctant to do that unless my original method is the problem.
As for the topo question and the hole not patching - it seems a bit of a glitch that the topo doesn't heal when the pad is reomoved, but your solution is an acceptable work around if necessary. My only question (because I have a much more significant hole to fill in another area of the project) is how do you get the new TOPO patch to "snap" to or conform to the existing topo if the surface is not level and is much lager, has many corners, etc. Please see the attached image.
Once again, any light you can shed on this would be greatly appreciated... and while you are at it (sorry) I have a related, but different pad/topo question that I posted that has not recieved any useful responses. That post is called "BUILDING PADS DON'T SEEM TO RESPECT PHASES". Could you please take a look at that and give it a shot? Thank you for your patience.

(PS, the pad creating the hole in the attached image is not part of the demo phase questions, but is actually from a future phase and is related to my other post referenced above in the last paragraph, but is useful for both questions.)
