I have a project which will be overcladding an existing bungalow with insulation. I have an as existing model of the house. The roof and floors are easy to do by adding the insulation as slab / roof as an additional layer to the existing build up.. but what do I do about the walls.
Option 1 - add a new layer to the existing wall - but then I have to mess about with several walls of different heights as there will be some areas that are not insulated and perhaps even different thicknesses of insulation.Seems like you do mean skin, when you say layer. You can use solid element operations to trim the different skin heights. See, for example:
Option 2 - draw a new wall of just insulation on the outside of the existing wall, but then how do I deal with the windows and sills etc?In a few cases this method is useful - and you then have to use an "Empty Opening" (from door or window tool) to cut the hole in the extra wall. This is a lot more work, requires coordination of both sets of openings to keep things correct, and may not work out at all, depending on what you are doing with the trim/sills/etc.

Illustrations better in the article above - if you can picture doing that with solid element subtract. This article uses SEOp, but does not illustrate composite walls - so you have to imagine that part here:Option 1 - add a new layer to the existing wall - but then I have to mess about with several walls of different heights as there will be some areas that are not insulated and perhaps even different thicknesses of insulation.Seems like you do mean skin, when you say layer.

Edit: oops, sorry. That article is using complex profiles now, which you don't have in ST2011. A similar article existed for composites and solid element subtract ... will see if I can find it...
