ATH Dimensions > Dihedral angle by specifying points
Command input:
ath_angle_rafter
Draws an auxiliary line between two surfaces and measures the ridge or throat angle.
The two areas are each determined by entering three points.
Input request
Specify the first surface
Specify first point or [?]:
Enter a point that lies on the first surface.
With the option ? you call the help.
Specify the first surface
Specify the second point or [Undo/?]:
Enter another point that is located on the first surface.
Specify the first surface
Specify the third point or [Undo/?]:
Enter the last point that lies on the first surface. The first surface is uniquely determined with this point.
Specify the second surface
Specify the first point or [Undo/?]:
Enter a point that lies on the second surface.
Specify the second surface
Specify the second point or [Undo/?]:
Enter another point that is located on the second surface.
Specify the second surface
Specify the third point or [Undo/?]:
Enter the last point that lies on the first surface. This point also uniquely identifies the second surface and displays the calculated surface angle on the command line. In addition, a ridge line is drawn.
Dihedral angle xxx.x°
Specify position of the dimension line:
The angular dimension is in the middle of the ridge line. Enter the position of the dimension.
Note
• The ridge line is created on the layer for the auxiliary line. Layer settings may be adjusted in the Dialog box System layer.
• The dimensioning of the ridge angle is done with current dimension settings.
