gester Posted May 5, 2014 Share Posted May 5, 2014 hi, i've got two questions: 1. the roof. is there a possibility to model a roof with two slopes, which is a hip roof (not gable !) ? i enclose a section scheme. 2. the wall. why the walls don't cut out the upper slab layers in a section generated from the model ? those slab layers have an edge offset auto-bound setting of 'inner face of wall core', and the walls have the cores defined. in spite of this, the wall core doesn't cut the slab. have i done anything wrong ? thanks, rob Quote Link to comment
mike m oz Posted May 5, 2014 Share Posted May 5, 2014 Roof: do it manually with separate roof face objects for each separate face and slope. Quote Link to comment
SonnyLuong Posted May 5, 2014 Share Posted May 5, 2014 To me, it looks like you have chosen the brick veneer line to reference you slab, thus your slab extends all the way to that veneer line. You need to reference that inner core line for your slab to be bound within that boundary then your wall well go straight up its full height. I don't think the wall will clip out the slab automatically. Quote Link to comment
gester Posted May 5, 2014 Author Share Posted May 5, 2014 @sonny the slab goes to the outer face of wall core (in order to be covered by the outer insulation). the wall is supposed to stand on the reinforced concrete part of the slab (the bottom 22 cm), and not to go straight up to the slab height (which is 36 cm). in archicad you can do this by boolean cut outs. i'm just experimenting with the slab settings, but neither of the slab components' options seem to work: slab preferences -> component selected -> edit (slab component attributes) -> edge offset (auto-bound). there are 7 options there, including inner and outer faces of wall, wall core and wall component. in the section viewport there is no physical difference between the choices. update: the manual entry for slab components (setting the negative offset values for the core thickness) WORKED ! (the screenshot enclosed) the solution is but only for the outer walls, i don't know how to influence the inner walls. and the manual entry for this particular slab components doesn't work for outer walls with different thickness. any thoughts? rob Quote Link to comment
gester Posted May 5, 2014 Author Share Posted May 5, 2014 @mike the roof faces seem to work so far, even smoother than i've imagined. hope it stays this way thanks. rob Quote Link to comment
Guest Wes Gardner Posted May 5, 2014 Share Posted May 5, 2014 @ Rob, Can you post up a piece of your project? It might be something as simple as some settings in the "Advanced Properties" of the viewport...as I understand what you're doing, it should be working... Wes Quote Link to comment
gester Posted May 5, 2014 Author Share Posted May 5, 2014 @wes here are a few screenshots of the project. thanks in advance for your time. rob Quote Link to comment
gester Posted May 5, 2014 Author Share Posted May 5, 2014 i could eventually cut out the walls footprints while editing slab (cutting only particular components of the slab), but it's not intuitive and each wall translation will have to be reflected in new slab edition. is there any other workaround? rob Quote Link to comment
Dieter @ DWorks Posted May 9, 2014 Share Posted May 9, 2014 You need to use two slabs, one for the construction slab and one for the finish. Then you have to BIND them correctly with the right settings for both wall and slab to be able to let the walls cut out the slabs. It works, but you have to do it like VW expects.

gester Posted May 9, 2014 Author Share Posted May 9, 2014 yeah, it makes sense. i have to do it for the last slab, which is bent in 3d. btw, how do you mean 'bind them'? i thought the construction slab is extending to the wall cores outer face (i can manage it manually, like in the 3rd shot from my post #197875), and the finish slab is being modelled when the walls are already set (like in real life), within the rooms, right? and yes, the troubles remain with the door areas. or do you mean the finish slab everywhere, not cut in pieces of each room size? thanks for input. rob Quote Link to comment

You bind your structural slab to the outer walls, and your finish slabs to the walls surrounding them. If you set the components correctly, the slabs will follow the walls and cut them out at the correct places. You will need to add pieces where there are doors, or cut out at stairs, but it's the way to go. Quote Link to comment
gester Posted May 12, 2014 Author Share Posted May 12, 2014 @dieter i still don't get it. you bind them manually or using the components settings? rob Quote Link to comment
Dieter @ DWorks Posted May 13, 2014 Share Posted May 13, 2014 @dieter i still don't get it. you bind them manually or using the components settings? rob When you select a slab, you will see of the slab perimeter is manually done or created by the walls it is bounded to. If you click on this, you can choose to bound to walls. I have a Dutch version, so it can be that my translations are wrong. Sorry for this. When you then set the components of the slab correctly (the setting to where it must go relative to the bounded walls), then they will cut out the wall. If it is not yet clear, I can make a picture of it. Just let me know. Quote Link to comment
gester Posted May 13, 2014 Author Share Posted May 13, 2014 (edited) dieter, ok, so it's the floor plan bounding. i can do this while creating a slab (bounding to the walls automatically or via manual polyline shape). there's but no way to change the manual bounding to the 'pick boundary' when the slab is already created, if that's what you mean. the selection returns to 'manual', when clicked. i can't thus see the components in the object info, the button is greyed-out (the one under the selection to the right on the pic). is this the right interpretation of what you've posted? update: ok, the slab was determined earlier, so the components are available from the settings of this particular slab, for all its appearances in the project. i can set the bounding here (auto-bound to the wall or core faces - outer or inner), but it doesn't work the way i want them (see my previous posts). rob Edited May 13, 2014 by gester Quote Link to comment

Select 'pick boundary' and immediately after that, start selecting the walls. You can't do anything in between, or it will not work. Here's a picture of what I mean. If you need more details, just ask, or post a file with what's not working. I know this can be hard to grasp at first. Sorry if my explanations are not always that good.
