Part Maker Updates (new features not covered in the standard PM documentation)

Shear Correction Factor

New statement for Create & Modify commands:

SHEARCF = f
or
SHEARCF = length, width
or
SHEARCF = 0

This defines a Shear force Correction Factor that applies to certain holds having a double bottom constructed such that shear force is carried by the end bulkheads. The correction factor may be given directly, as in the first form of the statement, or the appropriate length and width measurements may be given, allowing the program to calculate the factor. If zero is given, as in the third form, the correction factor is "turned off" for that part. If the length and width are given, the factor is calculated as

f = 1.0 / (1.0 + 1.5 * x)

where x is the ratio of length to width raised to the 1.65 power.

In the LS shear corrections, f is applied as follows,

dS = (Sa - Sf) * 0.5 * f

where,

dS - shear force addition for the length of the tank or hold,
Sa, Sf - uncorrected shear values at the aft and fwd ends of the tank or hold.

Maximum number of Critical Points

Increased from 9 to 99 for the READ and CRTPT commands.

Reference Number

Any reference number field in the second line of the geometry file no longer needs to begin with a digit for the READ command.

Comment Lines

Any comment lines may precede as well as follow the miscellaneous information lines.

Cylinders may have any orientation

Also FILL and TRUE parameters are available on CYLINDER statement.

Expanded BGI driver support

A new parameter is available at the DOS command line for PM to enable it to
use BGI drivers for the graphics display with the DISPLAY command. The new format for the PM command follows:

     PM [urunfileu] [/M] [/DR:udriver nameu,udriver modeu]

Driver Name is the name of the driver file (including DOS search path).
Driver Mode is an integer value which is necessary to indicate which graphics mode to use. Your BGI driver documentation should indicate what mode will work best. All drivers have a mode 0, but you can just experiment until you find one that works well.
For instance, if you are using an ATT Display Enhancement Board and have
a driver called ATTDEB.BGI, you would use the following command:

     PM /DR:C:\GHS\ATTDEB.BGI,0

If you wish to use a particular driver and mode permanently, you should
use the following commands in your GHS directory from the DOS prompt:

    copy pm.exe pmexe.exe     echo pmexe %1 %2 %3 %4 %5 /DR:C:\GHS\ATTDEV.BGI,0 > pm.bat     erase pm.exe

Command lines (including continuations) may now be up to 1000 characters

Longer file name paths allowed: up to 80 chars.
