Different claddings, one wall

[Jere]

I apologise if this has been covered before, I've been searching for quite some time and haven't found the answer yet.

Basically, I have a wall that has brick or CMU for the first metre or so, topped with a sloped sill, and stucco on the upper half of the building. Without using an add-on or GDL, how can I properly model this wall? It doesn't need to be perfect as I can fix it up in a detail window, but it should be fairly accurate.

Here's what I was thinking of doing, let me know what you think:
Solution #1:
Step 1: Draw full height wall with drywall, studs, sheathing, stucco.
Step 2: Draw another "dummy" wall to the height of the top of the sill and by using SEO, subtract the the stucco from the full height wall.
Step 3: Draw another wall representing the brick.
Step 4: Model the sill using slabs? roofs?

Question: if I do this, what do I do about doors/windows that are located in both parts. Just put the doors/windows in the main wall and add empty openings in the brick wall?

Solution #2:
Step 1: Draw two stacked composite; one with stucco, one with masonry.
Step 2: Model sill same as above.

Again, what would I do with doors windows in this case? Should the stacked composites be on different stories?

Thanks for your help.

I had the same concern about the Cadimage add-on. Here is their reply to my query:

Its always a difficult issue. e.g. if you only ever use the standard lib parts on a project, then if you send the project to a third party & they don't have these objects, then there will be an issue. you can create Archive version of your files which Includes all the lib parts within the file. However this tool uses the standard GS accessory object with some of our own versions for the various accessories. These could be included in an Archive file but there may be issues editing the objects in another copy of ArchiCAD that doesn't have these loaded. But if all objects in the loaded lib are included, they will at least be able to view if not edit these lib parts.
