CAEPIPE Version 6.10 August 19, 2009
------------------------------------

    o New feature added to Merge CAEPIPE Models. This feature skips Analysis Options, Load Cases, Wind Loads, Time History, Spectrums and Force Spectrums from the selected model for merging. On the other hand, it merges Materials, Sections, Loads, Beam Materials, Beam Sections, Beam Loads, Pumps, Compressors, Turbines and Elements into the current model from the selected model for merging. During merging the models, CAEPIPE checks for duplication of nodes and will give an option for renumbering the elements. Pressing "Yes" will renumber and merge the model, otherwise it will merge without renumbering.
    o New feature for translating and rotating the graphics model in Graphics Window using a mouse.
      In Translation mode, use
      Shift + Mouse Scroll Button Up and Down for Horizontal Translation of Model
      Ctrl + Mouse Scroll Button Up and down for Vertical Translation of Model

      In Rotation mode (Turn):
      Shift + Mouse Scroll Button Up and Down for Horizontal Rotation of Model
      Ctrl + Mouse Scroll Button Up and Down for Vertical Rotation of Model
    o Carpenter & Paterson Hanger Catalogue is updated to the latest version.

    o In "Coordinate Frames", View->Distance command can now compute the angles too for the line connecting two nodes (phi and beta. i.e., Angle in XY Plane and Angle from XY Plane).
    o LCS (Local Coordinate System) is now shown for Nozzle element through Nozzle List Frame->View->Show LCS or Results Frame->Other Support Loads->View->Show LCS or Nozzle List Frame->Nozzle Element->Mouse Right Click->Show LCS or Results Frame->Other Support Loads->Mouse Right Click->Show LCS.
    o Seismic Displacement and Rotation can be Exported/Imported via mbf using the comment SEIS(x,y,z) and SERO(rx,ry,rz) respectively.
    o Settlement Displacement and Rotation can be Exported/Imported via mbf using the comment SETT(x,y,z) and STRO(rx,ry,rz) respectively.
    o Lisega Hanger catalogue is updated to the Latest version. See catalogue for details. Available Hanger Numbers are 21 & 22, Ranges are 1,2 & 3 and Types are 18 & 19. In Hanger Report for Lisega, size column will report as Hanger Number, Type and Range instead of Hanger Number, Range and Type. For example, hanger having a spring rate of 2.1 N/mm, vertical travel of 30mm with load 440N will be reported as 21D.193 instead of 21D319.
    o Materials, Sections and Loads Inputs are shown graphically using Color Codes in Rendered Graphics. Press the "Color Graphics" icon available in Materials, Sections and Loads List windows to execute the command.

    o Bug Correction: Flange reporting was performed for Maximum of Operating 1 and Operating 2 even when the Operating 3 was analyzed.
    o Bug Correction: Assertion Failure when turn OFF the "Hydrotest Load" from Loads menu.
    o Bug Correction: When the Operating condition (T3,P3) was input for a piping system with buried portion, support loads for (W+P3+T3) were not reported correctly in all earlier 5.xy versions of CAEPIPE.
    o Bug Correction: When the Hydrotest load was selected for Text/CSV file printing with Piping Code = ASME Class 2, the stress values corresponding to SL+SO was printed in Local Element Forces instead of SL.

CAEPIPE Version 5.22 February 28, 2008
--------------------------------------

    o Bug Correction: For API 617 (Seventh Edition, June 2003), Forces and Moments were resolved with respect to the largest Nozzle of the compressor among all the compressors, even when the stress model had more than one compressor.
    o Bug Correction: For Rotating Equipment Reports, selection of Load Cases (W+P1+T1, W+P2+T2, etc.) through an icon on the toolbar did not change the results screen.

CAEPIPE Version 5.21 December 24, 2007
--------------------------------------

    o 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.
    o User can now import multiple Time functions from a text file. Each function should be separated by a delimiter "-1.E11". See example: sstusa.com/download/521tfunc.txt.
    o 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.

    o 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.
    o 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.
    o Refer Appendix-A of ReadMeSupplement_521.pdf for more details. (sstusa.com/download/ReadMeSupplement_521.pdf)
    o 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 upto 5.15.
    o Bug Correction: When Piping Code = EN13480, program crashed when trying to print the occasional stress contour plots.
    o Bug Correction: Pressure field was not disabled when reviewed through Results window->Window menu->Layout->Options->Analysis leading to an "Assertion failure."
    o Bug Correction: Data types such as Anchor, Guide or Restraints placed on JPIPE and JBEND element types were not rendered properly.
    o Bug Correction: It was not possible to enter more than 4 characters in the "From/To" fields of Distance measurement command through Coordinates List window->View->Distance.
