Option Description
Check box When using a prism to check a design profile,
it is important to take the prism radius into
account.
The measured point is projected by a dis-
tance equivalent to the radius of the prism in
a direction perpendicular to the tangent of
the design profile.
When this box is not checked, the design
profile is compared to the coordinates of the
centre of the prism at the measured posi-
tion.

culation.
In 3D viewer, a plot of the measured point
regarding the design profile is displayed.
