Problem:

What, if any, are known issues or limitations with rotating piping?

Solution:

 AutoPIPE rotates the piping geometry correctly. However, it does not rotate the component's directional settings.

Example, an anchor is attached to a pipe that is on the X-axis with flexible stiffnesses and thermal anchor movement specified; Trans Stiff = Dx = 1000 ib/in, and thermal anchor movement T1, Dx = 2.5 inches. The segment is selected and rotated on the horizontal plane 90 deg using the Edit > Rotate command. The anchor is graphically shown correctly on the end of the segment now rotated to the Z-axis, but the anchor's trans stiff and thermal anchor movement are still the same; Dx = 1000 in/lb & Dx= 2.5 inches, respectively. Again, the directional data is Not updated with the piping component.

Components affected:

a. supports
b. anchors
c. Concentrated Force
d. Impose Support Displacement
e. Distributed Load

Anything that requires a direction input
