6.7 Overlay Elements
Pontoon
Reference point: Center of base element
Linear superimposition (“linear overlay”)
Parameters
XF Reference point shift
ZF Reference point shift
R  R>0: Rounding radius
 R=0: No rounding
A Angular length
LS Length of wedge sides (projecting element parts are cut at
the “points of overlay”)
B Width of base element
W Angle of rotation: The overlay contour is rotated by the “angle
of rotation.”
“Linear overlay” soft keys
Enter the length (instead of end
point)
Enter the angle
Parameters
X Starting point, position of the first overlay element
Z Starting point, position of the first overlay element
Position (see illustration)
 1: Original position: Inserts the overlay contour in the
supporting contour “as is.”
 2: Normal position: Rotates the overlay contour about the
slope angle of the supporting contour element and then
inserts it in the supporting contour.
Q Number of overlay elements
XE End point, position of the last overlay element
ZE End point, position of the last overlay element
XEi Incremental end point
ZEi Incremental end point
L Distance between the first and last overlay element
Li Distance between the overlay elements
a Angle (default: Angle of the supporting contour element)
