the arm and leg links simultaneously, by moving
the link with the Move transform, instead of using
scale. Rubber-Band mode scales both the link and
its child in a single step.
This is particularly useful when fitting a biped

(page 2–1076). For example, rubber-banding
the upper arm rescales the upper and lower
arm objects and moves the elbow link without
affecting the posit ion of the shoulder or the wr ist.
If you’ve spent a lot of time getting the fingers in
the r ight place, you can reposition the elbow by
rubber-banding, without affecting the hands.
RVT Link
When working on Revit projec ts, you can
import/linkDWG,DXF,DGN,RVTandimage
files. These fi les can contain 2D and 3D geometry
to help in the construct ion of your projects. Raster
images can be imported as background images
into your Autodesk Revit project or as visual aids
needed during the creation of a model.
When you’ve exported the project to a DWG file,
RVT links are comparable to xrefs in an AutoCAD
drawing.
For more informa tion about the Import/Link
features of Revit, refer to the Autodesk Revit Help
file.
Sample Range
Low sample range can cause jagged-edged shadows.
Higher sample range causes soft-edged shadows.
Sample Range affects the softness of t he edge of
shadow -mapped shadows (page 3–1010).The
sample range determines how much area within
the shadow is averaged.
Small values reduce t he area that is averaged,
effectively bringing the edge of the shadow inward,
producing sharper-edged shadows. Sharper edges
can cause aliasing.
Large va lues extend the a rea that is averaged,
effectively bringing the edge of the shadow
outward, producing softer-edged shadows.
