Can you switch off the display of roof layers in plan ?

Hi,

We have a courtyard structure that comprises an insitu concrete slab, which is to have the top surface cast to falls for drainage.

At the moment we have the roof finish build up that includes, insulation, finish and a concrete topping that is laid to falls across the structural slab (ie the concrete topping is the variable thickness element).

It works just fine, and provides the overall detail that we are after.

However, we need to produce a plan that shows the concrete topping so that we can use spot levels and gradients to dim out the falls for the casting of the slab. Although we have included the concrete topping in the finish layer, it will be built in with the concrete slab. The reason we have done this is because the slab is continuous over a large area, whilst the finish layer (including the concrete to falls) is in isolated sections around the courtyard - so treating it as a separate assembly provides much greater flexibility.

Can you have a plan view that either isolates a roof type layer - or hides specific layers ?

I know parts can provide this sort of functionalilty in section views - but even when I create a call-out of the roof plan, it seems that parts cannot be used with roof assemblies to hide upper layers.

Anyone have any ideas ?

We do not want to include the gradient topping as part of the slab build up - mainly because of the complexity of the courtyard form, and the need for the topping layer (and gradients) to be formed around openings, stairs and built features in the courtyard.

Many thanks

We have tried the approach of having the insulation and roof finish as a separate roof assembly - but can you have it automatically follow the profile of the surface below ?

ie - in this image, the concrete topping is laid to falls as a separate assembly from the main structural deck - although they are joined so you don't see the separation line.

This works fine for getting the gradient and spot level info onto a plan. But obviously the roof build up above is incorrect - how can you have it follow the profile of the roof below ?

Thanks

Hi,

You are on a right track.

Just increase the insulation thickness to so it would will the void, and then join the concrete topping to the insulation.
Revit will subtract the overlapping insulation so the remainder will follow the concrete's slope.
In terms of scheduling, the volume of the insulation (if you need it) is going to be correctly reduced.
