Build – Subsample – Adaptively – Points
Reducing the Selected Points Adaptively
This command is used to reduce the points selected in the currently displayed element so that surface points
density in simple-shaped areas is lower than that in complicated-shaped areas.

The elements selected before execution of this command will be divided to triangular polygons.
Parameters for [Build-Subsample-Adaptively-Points] Dialog Box
Number of points Reduces the current number of points to the specified number. When the [Apply] button is clicked,
the current number of vertices will be displayed. (The default for the “Number of points” param-
eter is set so that the number of selected points will be reduced by 50%.)
Range of errors The program reduces data in accordance with the value that you enter. The value serves as a gen-
eral yardstick for the amount of reduction-induced change in model tolerance.

The default setting is “0.2”.
Fix boundary Among the selected points, the points present on the boundary of the hole will be excluded from
data reduction.
Operating Procedure
1 From the element list, select one desired
element.
2 Select the desired points.
3 From the [Build] menu, select [Subsam-
ple] –[Adaptively] then click [Points].
The [Build-Subsample-Adaptively-Points] dia-
log box will appear.
• The selected element will be ready to be displayed
in all windows. It will be displayed if it is not dis-
played in the active window or the windows for
which all the elements are set to be displayed.
4 Set the parameters.
5 Click the [Apply] button.
The data of the selected points will be reduced
according to the parameter settings so that
surface points density in simple-shaped areas
is lower than that in complicated-shaped areas.
• The polygons comprising the selected element
will be triangulated.
• If you change the parameter settings and click
the [Apply] button again, the data comprising
the points will be reduced according to the new
parameter settings.
