the arm and leg links simultaneously, by moving
the l ink with the Move t r ansform, instead of using
scale. Rubber-B and mode scales both the link and
its child in a single step.
This is particularly useful when fitting a biped to a
skin prior to applying the
Physique modifier (page
2–927)
. For example, rubb er-banding the upper
arm rescales the upper and lower arm objects and
moves the elbow link without affecting the position

RVT Link
When work ing on Revit projects, you can
import/linkDWG,DXF,DGN,RVTandimage
files. These files can contain 2D and 3D geometry
to help in the construction of your projects. Raster
images can be imported as background images
into your A utodesk Revit project or as visual aids
needed during the creation of a model.
When you’ve exp orted the project to a DWG fi le,
RVT links are comparable to xrefs in an AutoCAD
drawing.
For more information 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 the edge of
shadow-mapped shadows (page 3–1104) .The
sample range determines how much area within
the shadow is averaged.
Small values reduce the area that is averaged,
effectively bringing the edge of the shadow inward,
producing sharper-edged shadows. Sharper edges
can cause aliasing.
Large values extend the area that is averaged,
effectively bringing the edge of the shadow
outward, producing softer-edged shadows.
