while on the subject of roofs, i would just like to confirm if:
1. you can't trim a roof to another roof?
2. you can only trim walls that actually intersect a roof? e.g. a wall 3m high cannot be trimmed to a roof whose base is at 4m?
3. if yes to 2, you have to raise the height of the wall so it intersects the highest part of the roof before you can trim it?
4. you can't pick which roof to trim your walls to?
5. after trimming a wall to a roof, you make changes in the roof's height/slope/configuration, you have to re-trim the wall to the 'new' roof?
6. in revit, you can 'attach' your walls to a roof so that the walls' configuration (height, shape) automatically adjusts to any changes later made to the roof. can you do something similar in archicad?
TomWaltz wrote:why indeed? sorry, revit-speak. there's only one command for trim/extend in revit and it only says trim on the icon, thus my use of the word 'trim' to mean both trim and extend.
1) yes, you can
2) why would a 4 meter high roof trim a 3 meter high wall? If you want to extend the wall, yes, you can.
TomWaltz wrote:i've read the section on roofs before posing my questions. some things are not covered in manuals/guides and even when they are they are not always clearcut and some problems can't simply be foreseen. that's why these forums exist, right?
Most of these are in the Archicad user manual.

5) it depends on which trim command you use. If you use "Trim to Roof" (which allows all of the above to work), then no. If you use Solid Element Operations (which does not allow all of the above to work) then yes.
David wrote:thanks. the group was suspended when i worked on the polyroof. i understand that 'alt + G' is a temporary suspend command so shouldn't the polyroof automatically revert back to its original grouping?
Make sure to Suspend Groups, Polyroofs are grouped by default.

In cases like these, the Custom Profile should be a wall placed perpendicular to the building wall at the depth you need to express the new element, defining your quoin stack, for instance. Or your brick arch.
To edit a custom profile, sketch over the elevation with a fill to redefine the custom profile, pasting the new fill into the custom profile window or edit the defining fill right in the custom profile window.
Yes, relative to Revit, there's an extra initial step, but each custom profile is saved, so there's payback for repeating situations.

Using ArchiCAD Construction Elements (such as Slabs), create the Door Panel on the Floor Plan. In case of Door/Window custom panels, what you draw in the X-Y plane of the Floor Plan Window will be ‘stood upright’ in the Window/Door library part (rotated 90 degrees around the X axis – as described in the GDL Reference Guide). For other custom component types, this condition does not apply.

And you even get the option of making the profile "stretchable" in the limits of your choosing. However, with the "merge" option, you don't even need to go into the profile editing window.
I learned a lot of things about ArchiCAD while trying to solve the problem of the facade trim. Most of them what you can NOT do and the rest how to go about it in the most roundabout way.
You cannot:
1. edit a wall's profile (or any profile for that matter) in elevation/section.

I'd really suggest you fully learn to use the program before making pronouncements such as the above.

If I had the answers I wouldn't be asking for help here. Please take a look at the the facade I'm working on (attached two posts before) and tell me how I should go about doing that in ArchiCAD. I would really like to know the simplest and most direct way of doing it.
