To Defined Arc length for Pipe Bends in OpenPlant Modeler.
In OpenPlant Modeler, it has been observed that Length Property for pipe bend calculation displays as twice the arm length of bend, i.e. Length = 2 * Pipe Bend radius along with clamp length (Length to Bend Point, Length after Bend Point).
See image below for default calculation in OpenPlant Modeler. Length = Length to Bend Point + 2 * Pipe Bend radius + Length After Bend Point.
Where, Length to Bend Point = 100 mm Length after Bend Point = 100 mm Pipe Bend radius = 150 mm
Length = 100 + 2*150 + 100 = 500 mm
Actual calculation should be, where,
D = Diameter of Pipe
Note – In OpenPlant Modeler unit conversion 1” = 25mm hence desired value would be, = 1.5*4 *25*PI/180*90
= 235.619mm
Considering Length to Bend Point = 100 mm & Length after Bend Point = 100 mm,
Updated length would be = 100 + 235.619 + 100 = 435.619 mm
See below steps to overcome this situation by defining a new property in schema through class editor and applying the mathematical expression in EC expression.
