Two Floors - Three Wall Surfaces?

[KTKArch]

Small Commercial project has two common issues. This is truly a single story space. It is a metal bent framed building w/ concrete block infill walls. In one corner are lower ceiling bathrooms. 

Issue One: Model as Two floors or One? There is only one true floor in this building, yet there are small two story or covered spaces inside the building. How do you tend to handle this scenario.

Issue Two: One wall has three finishes: Above one of these 'interior' spaces the exterior wall is the simple block finish. The wall in the interior space has the two commercial finishes for bathrooms on the furred out portion. Standard drywall over 4' of solid surface.

 

Another item is modeling a steel bent roof. Steel structure is under Purlins. Insulation between purlins. Bents are tapered so no good way to model them and no ceiling surface. What options do you have for this? Didn't find any sketchup models for tapered bents in the 3d warehouse either.

not sure about the Bent Metal options but build it as 2 storeys then use invisible railings or walls to define the 1st floor "rooms" and then select the other area and define it as "open to below" ,(same as you would for a mezzanine floor or open landing basically)

from another post on HT:

mezzanine floor

make the 1st floor (8ft?) , setup your bathroom, then add another (8ft) floor on top, turn on reference display and make an invisible wall along the edge of the bathroom wall/area then you can select the area where there should be no floor and on the room dbx specify it as "open below"

here is a KB Article that might help

Thanks for sharing. In this case the 'open to below' single story spaces have 10' garage doors in them. So setting the second floor to the top of the 8' interior spaces messes with the walls. Fixable but just another hassle.

 

Next time I'll try just two stories over the stacked space. And raise the roof/ceiling in the single story space to match.

yep sorry the (8ft?) in brackets was for the other post I made, where they had a 16ft garage/warehouse , you need to set the heights to whatever you need them to be eg 12ft 1st floor, 10ft second floor for a 22' building ,though you may need to play with it some depending on floor thicknesses etc if the building height needs to be exact...

You might start with a building section and plan where the walls and roof connect to the bent frame. Building your building shell, create a cross section and use that shape to create the "Bent Frame" shape. copy that shape outside of the building model.

Model the bent frame from polyline solids , Block, add to lib. then move  back to the Building shell, in plan move to your desired locations.

Agreed! It's been a while since I had to do something similar with half exposed round timber trusses...thanks.

 

As for the multiheight first story...I set the open area to 13' ceiling height. Then built a second floor only over the lowered (8' ceiling) area. I've not bothered about the windows crossing between these areas yet, and with the open ceiling I've had to turn the interior attic walls to invisible so the exterior attic gable walls remain on. Much more effective than two complete stories so far.
