Parapet Help

Anonymous — Fri, 08 Jul 2016 09:39:36 GMT

Hi everyone.

Can someone please help with how to draw my parapet correctly? As you can see from the picture I have drawn a parapet but above the roof I want to change the internal plasterboard finish to an insulated cladding panel. Both the finishes above and below the roof need to follow the sloped roof profile. I also want to add a gutter to the roof behind the parapet but again I'm completely stuck with that two.

After a two day basic training course I've been using Revit 2 weeks so my knowledge and skills are pretty basic and I've been trying to figure this out for 3 days now. Any help is hugely appreciated.

Thanks

Claire

Think of the construction. Change the sentence "How can I draw this correctly?" for "How is this built"? Then, you will start understanding better how to model it correctly. Revit is virtual construction and not drawing. Maybe the parapet needs to be a different type of wall, not the same that you are using for the rest of the facade. Try to sketch by hand the wall section with all its materials and dimensions, and then model just that. If you need to stop the wall before the roof, then, do that, and create a different wall type that goes from the roof to the top of the parapet.

Hi Alfredo

The modelling bit is the problem. I know how to build this type of parapet as I have detailed it lots before but I used CAD. I don't know how to stop the wall underneath the sloping roof then add a different wall type on top. Do you have any tips please?

Can you provide a section detail of how you want it? Then we can make specific modeling suggestions.

Hi Chris

Here is a pic of what I have done before in CAD. I've put simple notes on to identify finishes. The steelwork I will get from a structural engineer so I can ignore that for now I guess.

I'm happy to answer more detailed questions about any specific bit...

The model looks like this:

You could - instead of stacking two walls on top of each other manually - create one Stacked Wall type that includes both of them. If you set the MAIN type on the bottom with a variable height, and the PARA type on top with a 2'-6" height, and then give the whole thing a 2'-6" positive offset above its top constraint, you will get exactly the same thing I've shown, except that:

1. You won't have to use the Join tool to get rid of the separation line between them, and...

2. You won't have to model them separately on successive Levels.

Both of those things can be time consuming if you have a large, complex project to model.
