<drawing1.dwg>

This object is Linked Geometry

containing one or more

componen ts found in

drawing1.dwg

,whichisa

drawing that is linke d to the

Revit drawing. This linkage

is comparable to an xref in

AutoCAD.

Note: It is possible for instances of the same Rev it

element to subdivide differently into 3ds Max

objects. Revit elements are considered instances of

the same element if their category, fami ly, a nd type

name are exact matches, and this will affect their

instancing behavior for 3ds Max funct ions such

as material propagation.

Revit Cameras and V iews

In order to navigate a Revit drawing more

efficiently, you might have set up a series of 3D

views by means of placing cameras at different

viewpoints around the d rawing. T he File Link

Manager and Import functions of 3ds Max allow

cameraviewstobetreatedas3dsMaxcameras.

You must meet two conditions in order for 3ds Max

to understand Revit camera views.

•Acameraviewmustbeactive

before

you export

the DWG file from Rev it.

Note: Onlytheactivecameraviewisexported.

• You have to make sure you’ve turned on the

Views (cameras) switch in the

Basic File Link

Settings dialog (page 3–436)

When the draw ing is linked to 3ds Max, that

camera and its target appear in the scene named

Camera:viewname

and

Camera:viewname.Target

Light Sources

Draw ing files, exported from Revit, can contain

light sources, however, they do not export with the

DWG or DXF files. What does get exported is the

3D mesh geometr y representing the light fixture.

Therefore, when you import or link the draw ing to

3dsMax,thelightobjectisstrictlygeometry,not

an ac tua l light s ource like a spotlight or omni light

that you can adjust.

These pieces of geometry are still useful in that you

can use them as reference points for placing and

aligning lights you add in 3ds Max.

DXF Files

Along w ith the ability to export DWG files, Revit

canalsoexporttotheDXFfileformat.Theonly

difference is in how they handle drawings that a re

linked (RVT links) to t he Revit drawing .

When export ing to DXF, the linked draw ings are

automatically bound to the drawing. Therefore,

whileexportingtoaDWGhonorsthelinked

drawingsandtreatsthemasAutoCADxrefs,an

exported DXF file will not have xrefs. Instead, the

linked drawings are converted to blocks.

The resulting scene organization will be slightly

different when linking or importing a DXF as

opposed to a DWG, but only when RVT links are

present in the drawing.
