    Our trials and not some much tribulations with floors

    We seem to have a lot of issues when working with slabs that has falls. At the moment we use not so desirable solutions and work-arounds - some which involves detail lines and modelling several slabs on top of each other. A lot of our jobs include to some extent part of external slabs around buildings or behind Ret walls etc. Note we are Struct Engineers and the point below refer to when view is set to Discipline:Structure.

    1. When having a slab where sub-points have been changed to suit for example external pavement AND having different slab thickness. See Sample 1 (very simplified) where we have a slab behind the ret wall but the reliving slab closest to the ret wall has a different thickness. I have found a Dynamo routine here that 'match' the levels between 2 adjoining slabs. It work great.
    2. Internal Edges; When modelling slabs with falls and you want to show the Interior edges - the 'fold line' of the soffit is shown in plans view. This make sense as there is a change of the soffit line - but it is not desirable to see both the Interior Edge (Fall Line) and the Hidden line of the slab soffit.
    3. Working on a job at the moment where the suspended carpark slab has falls BUT the soffits are horizontal. The fall across the top of the slab is constant but the soffit steps. At the moment I have modelled 1 slab to show the Falls - another slab to represent the soffit. This has been OK - but time consuming. My concern is when I later have to extract concrete volumes. Sample 3.rvt

    It would be great to be able to model a main slab and then 'highlight' areas with different slab thickness - like doing a local 'extrusion'. These subareas would be dependent on the main slab.

    If anyone have any comments or feedback on workflow on the above would be much appreciated.

    I can give you a few pointers.
    So, I am completely noob with dynamo so I wont try to add to that part.

    But as for the soffit lines, if you go into the view graphics controls *VV or VG shortcut* you can open "floors" and untick "show interior edges" this will solve a grand majority of the soffit lines you don-t want to see, but you may still have to linework over some pesky ones occasionally.
    I think this is the one to untick....just check out what the effect is of modifying some of the subcategories under "floors"

    As for modeling varying slabs and joining them together, this is how I have done it for a while now. I mean I have modelled roadways using floors *set to bitumen material* and then modifying the sub-elements to give the slopes, works just fine but takes a bit of hand calcs to get the job done. To be honest, there is no difference to your TOTAL volumes *as long as you modeled properly* BUT you will get tons of smaller slab pieces that kind of make no sense.

    You can reduce this problem a bit by adding a cut line in your slab when placing the falls, this lets you place a "fold" where you can change slope direction easily or have a flat portion and then a slope, rather than making two pieces to do the same thing. This is fairly situational though and wont cover all of the cases. Then you also have the option of modelling the slab in the "create new conceptual mass" editor, and making a 1 piece extrusion that does all the steps and falls you want, and in fact you can make much more complex and interesting volumes there where you can have the top surface and the bottom surface of your floor having different slope values. Basically the conceptual mass tool is pure 3D modelling and will be your panacea if you really MUST have 1 piece slabs. BUT you will need to create the levels, and import your outlines into the conceptual mass editor and work there then bring your 1 piece slabs into the revit project. Actually now that I think about it, this is probably the only solution you have if you want to make a solid 1 piece element with varying levels and slopes in it.

    Having said all that, multiple pieces does work, but yes for lists it can suck but this can be solved with a parameter, or even just type comments that let you group them together, or you can always add them to an "assembly" and then list that assemblies parts for your lists.
