Phases question

[CADMama]

OK - so here is the question I have been sent that I cannot answer:

I am working on a little addition to a building and adding a new EIFS and Brick Veneer over the existing CMU Block walls. What would the best way to do this. I am using Phases Existing - New Work. And the CMU wall is on the Existing Phase. If I add a new wall on the outside of the existing one my doors and windows wont go al the way through and even if I split one the wall to make them correct in plan the section/details dont look right. I could make a new wall type with both the new and existing and place it in the New Work phase but I am not really demoing the existing wall. (This seems problematic) In Autocad I wouldn't care - just add another line and do some trimming. Any ideas?

Any suggestions would be great,
CADMama

If your two walls are sharing a common edge, you can use the join geometry tool. This should create the affect you are looking for.

CADmama, another painful way to do it, if you had alot of windows/doors, would be to edit the wall in elevation and use the profile command to "cut out" your doors and windows. You can then lock the edges to the existing wall, so if you change the window/door size or move it, the window/door opening in the new wall will update automatically.

I had this same situation come up just recently: the block structural walls were to remain while the finishes were to be stripped & replaced. If you build 2 walls in the existing phase sharing a common face, place your doors & windows in the one to remain. Then use the join geometry tool (selecting the wall with the openings first) and the openings will cut into the joined wall. I'm not sure if it will work if you select the wall without the openings first.

Then switch to the new phase, demo the portion to be removed & add the new wall in its place. Again, join the geometry of the remainder walls to the new walls & the openings should automatically cut the new wall. It may get a bit screwed up where doors and windows are also demolished & the wall tries to "heal itself." Then you might have to resort to the technique described by johnf. But otherwise this method should work.
