Windows in multiple walls

[marcodebortoli]

Hi everyone,

I've been reading a lot about the multi wall approach = create a new wall type for each finishing, basically modeling as you build it.

In my project I have a very basic situation: CMU + exterior plaster + interior finish that may vary: tiles or plaster.

So I modeled 3 wall types, one onto the other and joined them.

When I insert a door or window, the opening cut correctly through the 3 walls but:

- in plan and section, walls do not wrap at inserts (obviously...) so the plaster do not return as when I use a single wall type with 3 layers = not a good detail

- in 3D you can see the lines of each wall and the CMU is shown (because it is butting to the window, obviously), no plaster is shown on the four sides of the window opening

Is there a way to solve this problem without using a window trim? My clients don't want any trim on w&d

I guess the answer is in the way the family is built...

I have tried to nest a new rough (empty) opening into the window family but the result is the window floating into a larger void.

I've added a plaster extrusion to this void but, when inserted, it does not cut trough all the 3 walls = not a good detail....

I am surprised that all the people that advocate for the multi wall approach have never encountered this problem.

If so, I could not find a clear explanation on how to solve it on may forum.

Please help with detailed instructions on how to build the window family and/or share your family so I can study it.

Thank you for your help!

What am I looking at in that screenshot? 2D or 3D elements?  Read my last post again. I addressed this in an edit.

Plan view of 3D model

That tells me nothing.  Open the Family, go to Plan View, turn Preview Visibility ON, and then select the linework.  What does the Properties say it is?  Detail Item?

Here it is

I don't what you want me to do with this, but all the model elements (frame, glass, etc.) are visible in all Views.  So, no "graphic  details".  Nor is there any wall closure Ref. Planes, for whatever that's worth

BTW: Do you know that you can use the Paint tool to apply the Exterior and Interior Wall Materials to the portions of the Window opening that do not get wrapped by the Wall Wrap function?  Maybe that's a nugget of information you can run with.

Thank you for your input, Barth

@ToanDN Could you explain how large should that column be? Does it need to be longer than the window width to have it shown in floorplan as if its wrapping?
