This function is used to
calculate the distance between two parts, and display the result in contour
plot. The control window is shown in Figure
5.14.1. The user needs to set the Source part and
Destination part. The calculation result is displayed on the Source part.

TOOL SET
l SOURCE
Select source part for
distance calculation.
l DESTINATION
Select destination part for
distance calculation.
2.
OPTION
l USE ELEM
If this option is toggled
off, the calculated distance is an absolute value. If this option is toggled
on, the element normal direction of two parts should be considered for the calculated
distance, and the calculated distance value can be positive or negative
depending on the normal direction of the source part. Figure 5.14.2 (a) shows the result when the option is toggled off
while Figure
5.14.2 (b) shows the result when the option is toggled on.
l BEST FIT
This option is used to
compare two parts shape. The user can select respective fit points in two
parts. The selection of fit points is shown in Figure 5.14.3(a), the result of fit calculation is shown in Figure 5.14.3 (b).
l MOVE SOURCE PART
This option is used to move
source part to destination part. After the BEST FIT option is toggled on, the
option is valid. In order for the advantageous comparison, source part is moved
to destination part after the calculation of best fit.
l TOLERANCE
This function is used to
control the calculation accuracy. The value should be greater than zero
l CRITERIA
This function is used to
control fit degree.
