… Viewing Results
Displacement Scaling:
•In structural analysis a default scale factor “multiplies” actual displacements.
•The scale factor can be changed using several built in values or to a user specified one.

… Legend Controls
The legend bounds can be manipulated to show result distributions more clearly for contour plots.
Max/Min values are unchanged
Click and drag contour dividers (or type in values) to specify contour ranges.

C. Contour Controls
The “Geometry” icon controls the contour display method. Four choices are available:
Exterior |
IsoSurfaces |
|
Slice Planes
Capped IsoSurfaces
“Exterior” is the default display option and is most commonly used.
“IsoSurfaces” is useful to display regions with the same contour value.
“Capped IsoSurfaces” will remove regions of the model where the contour values are above (or below) a specified value.
“Slice Planes” allow a user to ‘cut’ through the model visually. A capped slice plane is also available, as shown on the left.

… Contour Controls
Capped IsoSurfaces are manipulated by an independent controller:
•Icons allow isosurface cap to be top or bottom.
•The cap threshold can be controlled via the slider or by typing the value directly
