Hi All,

I'm an architect in need of some DESPERATE assistance. Currently I'm working on Revit 2013/2014(2013 at home 2014 at work).

I need to create an accurately modelled parking area with tarmac, kerbs, rainwater channels, etc. I have been provided with levels from a 2D survey of the existing which I need to factor in when I'm producing the proposed model. It would be great to be able to see both the existing and proposed against each other in section so I can see what cuts and fils are required.

Currently what I have done is create the surface using the 'floor tool'( as I require a layerworks buildup when in section) and have added points to the surface to create the falls. I literally have a site which slopes in two directions at the same time at varying positions.

When I draw a section through the surface it looks like a dogs breakfast and well it's just not producing the results I require. 

I have thought about creating a gridwork at 1Metre intervals, plotting levels at each and every grid intersection, gradually changing each point to create a SMOOTH TRANSITION between each point to provide an effective and ACCURATE section.

I am also trying to use 'FLOOR EDGE' on a sloped floor surface to create Rainwater channels and Kerbs, however, it just doesn't compute.

At the moment my sections look terrible when projected and I don't know how else to do it.  

If anyone could help it would be much appreciated.

Thanks a mil.

Ok after a bit of research i have worked out that the best way to add 3D profiles creating rainwater gutters and kerb details to sloped floor surfaces is to:

1) Create the sloped surface using the floor tool

2.) Draw a model line using the referace plane of the desired sloped floor plate

3.) Select the 'floor edge' tool

4.) Draw a floor edge by picking the drawn model line

The result is a floor edge profile following the line of the model line along the desired sloped path.

Still stumped how to effectively create an accurate and smooth floor to fall in two directions using a number of 2D survey points.

If anyone knows I'd really be interested to hear how you did it. Maybe this is where Revit is still lacking something unless I'm not aware of it. Is this time to go 2D?

You must not have searched the forums.  In this thread is a good tutorial:
