Hello all-

We have done some conceptual work and renderings using 3dsmax design 2011.  We are now moving on and would like to place the modeled site from 3ds max into revit.  I have been fighting with this for 5 hours and cannot find a clean and simple way to do this.  Does anyone have any tips?

thanks,

swegin

ummm... export to dwg then import into Revit. thats not ideal but it would work. is it a complex topo or is it flat?

it is pretty complex. The site has various slopes as well as some terracing.  I have exported the model as a dwg and that is what i am currently working with, but it will not let me model by face.  I can only create topography with "create from import" command which is resulting in a VERY crazy topo

here we go again..

you are trying to mix DWG lines with revit elements..

the two mix like water mixes with oil.. they don't mix..

if you know how to use 3Ds Max- then just leave the

thing in there and use it as a reference and build it in revit..

if you don't know how to use Max- then import from there

as a DWG into a SEPARATE session of revit as a MASS element..

then use it as a reference there.. again- you cannot bring

DWG lines together with revit elements.. THAT you

have to do in your head and with your eyes..

Try downloading a 30day free trial of Civil 3D, export your Max file to dwg bring it into Civil 3d and export out as a CSV file, import CSV into Revit

It is a Points File, it creates a toposurface based on a points file from a civil engineering software application.

A points file provides contour data using a regularized grid of elevation points.  The file must contain x,y,and z coordinate numbers  and be comma-delimited.

thanks for that information cadman- i have a CAD drafter that draws

site plans for my residential projects- so i probably wouldn't be

learning about comma separated values too soon.. but i will

ask them what they know about it..

It's like a point cloud.  Lots of different 3D programs understand points.   It will look something like this:

property float x

property float y

property float z

Although these are measurements with no scale, and not the same format as mentioned... this is .ply with the RGB values removed... Points in X,Y,Z are the simplest way to express a 3D surface, with coordinates for the vertices.
