Workflow recommendations for painting/decorating

[alexliz]

As per the title, guys: what workflow do you recommend for costing an interior refurb project?

A wall may span different rooms (say hotel, care home, school etc) and each room along the length of the wall may have different interior finish requirements - different paint color, wallpaper instead of paint etc.

How do you tackle this? Do you recommend segmenting the wall into many walls, one each for the various rooms? What happens if the room segmentation occurs at different points along the wall's two faces?

Many thanks for all your great ideas.

Thanks Ignacio, interesting approach. So, just to clarify: are you using the Opening's surface to calculate finish surface area? Also: does this not result in the 'paint', 'wallpaper' and other 'finishes' on your walls being subtracted from (as opposed to added on top of) your walls' outer surfaces?

I only got as far as shown in that comment –I was scheduling “opening area”, thinking of just “painting” with openings any finished surface that needs to be scheduled. 

For visual purposes only I have used in the past the Niche and Lesene window objects, which only allow rectangular shapes. Niche&Lesene windows, and I assume the same must be true for openings, really complicate the underlying 3D model (because Archicad cuts the full thickness, then fills in the remaining thickness, and I don't remember if there are similar infills above and below the opening). So that is why these “finish openings” should probably go to their own Design Option. Also for not having these openings cluttering everything during non-finish modeling. 

I've seen other approaches with room accessories and third party add-ons, but they are based either on zones (which is normally not good enough) or on walls (which requires splitting the wall for each finish change on either side). And manual approaches modeling everything as finish walls, with openings to match doors-windows. 

The beauty of openings is they move with the wall.  I suspect the area of doors/windows would not be subtracted (and in that case one would need to place the “finish openings” around the door-windows; either several openings, or a single L-U/C-O shaped one), but except for add-ons the other finish modeling options require even worse workarounds for door-windows.

It should work. Here is an overview of all the different parameters that you can add to the schedule:

Maybe you can cross check with some other parameters like window/door surface, number of wall parts etc to see if everything is picked up correctly.

Sometimes you just need to update the zone for it to behave.

Modeling wise, if the wall is spanning multiple rooms, or even stories (we model our exterior walls full height, so multi story usually, using detailed complex profiles), if we need to show the random accent wall, our method has been:

place a slab or morph over the wall, and have it overlap minimally (1/64" or less), place it on a different hidden layer.

SEO - subtract it to the wall in question.

And select the toggle to inherit the target surface to inherit from operator.

If there are windows or doors within that portion of wall, it is usually a morph that jogs around the opening, to not change the openings surface appearance.

We don't quantify sq ft or anything like that, This method is just meant for modeling & presentation appearance though.

Hi...

When I try to extract quantities from zones, I encounter delays with walls located between two zones. Where the area of ​​each face should be associated with each zone, both faces end up associated with the first zone placed, and each walk-around I devise is more tedious than the last. Oddly enough, if I don't need to filter by zones, I use the zone tool.

Could this be the source of the area discrepancy?

I've never tried calculating using zones and with modeled elements attached to the wall faces as finish elements.
