hm_wadlinesispointintestzone

Returns whether a point is inside a test zone by taking in the coordinates of the zone boundary.

Syntax

hm_wadlinesispointintestzone <option1> <value1> ?<option2> <value2>? ... ?<optionN> <valueN>?

Type

HyperMesh Tcl Query Command

Description

Returns whether a point is inside a test zone by taking in the coordinates of the zone boundary returned by hm_wadlinesgetadulttestzone and hm_wadlinesgetchildtestzone, along with the impact direction of the impact point. The impact point and zone boundary are projected to a plane perpendicular to the impact direction, then tested to find if the projection of the impact point is within the polygon defined by the zone boundary.

num_pts should always be provided before the points option.

Inputs

normal: The normal direction x/y/z of the plane to which the zone boundary and test point is projected. This is expected to be along the impact direction of the impact point.
num_pts: The number of points defining the zone boundary. Must be provided before points.
points: The ordered x/y/z coordinate values of all points of the zone boundary.
testpoint: The x/y/z coordinates of the impact point to be tested.
tolerance: Test points that are within this tolerance to the zone boundary are also returned as inside the zone boundary. Default 1e-6.

Examples

To test if design point 38 is inside a zone boundary:

set id 38
set pos [hm_getvalue designpoint id=$id dataname=position]

Errors

Incorrect usage results in a Tcl error. To detect errors, you can use the catch command:

if { [ catch {command_name...} ] } {
   # Handle error
}
