The Bend Angles rule (the BendAngles sheet in the Piping Specification.xls workbook) lists the preferred angles in the route pipe ribbon bar for the different NPD when routing a turn feature and the working plane is active.
Bend Angle (Required)
Type the bend angle you want to allow. Be sure to include the units of the angle. For example, type 90 deg.
Type the nominal pipe diameter (NPD) for which you want to define a valid bend angle.
NPD Unit Type (Required)
Specify the units for the nominal pipe diameter value you entered in the NPD column. For example, type mm or in.
Spec Name (Required)
Type the name of the piping materials class for which you are defining valid bend angles. The piping materials class that you enter must be defined on the Piping Materials Classes.
