• Units conversion between Spectrum unit types for the ordinate (Y-axis) is now possible, for e.g., between inch and mm., g's and in/sec2.

• User can now import multiple Time functions from a text file. Each function should be separated by a delimiter "-1.E11".

• Valve element has a new field called Valve Type. This information will be used in upcoming versions to differentiate between types of valves by changing the symbols during rendering.

• Hanger has a new field called "Hanger above". This should be used to specify whether the Hanger is connected above or below the pipe. Graphical symbol changes accordingly. Valid only for Hanger and User Hanger and not for Constant Support Hanger and Rod Hanger.

• User can change the Yield Displacement factor (between 0.04 to 1.0), used to calculate the initial stiffness in Buried piping analysis. See Options menu->Analysis->Misc in the Layout window. We recommend no changes unless there is a problem with convergence in the Buried Piping section of analysis.

• New feature to export the 3D piping model to PDMS as structural components (only graphics without attributes). This can be performed through File->Export to 3D Plant Design from inside the Layout window.

• API 617 is updated to Seventh edition (June 2003). See ReadMeSupplement_521.pdf for details.

• Bug Correction: For API 617, the resultant force and moments were resolved with respect to Exhaust Nozzle and not to Largest connection. This bug exists in CAEPIPE versions up to 5.15.

• Bug Correction: When Piping Code = EN13480, program crashed when trying to print the occasional stress contour plots.

• Bug Correction: Pressure field was not disabled when reviewed through Results window->Window menu->Layout->Options->Analysis leading to an "Assertion failure."

• Bug Correction: Data types such as Anchor, Guide or Restraints placed on JPIPE and JBEND element types were not rendered properly.

• Bug Correction: It was not possible to enter more than four characters in the "From/To" fields of Distance measurement command through Coordinates List window->View menu->Distance.
