Tow 6.0.1.6 - Critical Update
The SACS Tow program for SACS 5.2 SP3 is incorrectly including the SACS model loads as weights when the ‘AL’ (all load cases) option is specified on the TOWOPT record. If a LCFAC record precedes the ACCEL or MOTN records then the weight problem does not occur. The ‘AL’ option is used to include all of the SACS model load cases in the output model file from Tow. Without the ‘AL’ option specified the output model file from Tow only includes the inertia loads.
API RP2A 21st Edition Supplement 3 Update
The selection of the nominal chord thickness for the Thickened Can Reduction Factor in Section 4.3.5 was not correct for some T and X connection types. In general the new UC values are lower than those in the previous release. An increase in UC values was only noticed for short dummy stub members used as transportation connections.
Updates:
Corrected display of Asymmetrical cross-section neutral axes.
Corrected display orientation for Angle and Channel cross sections.
Corrected the display option for undefined members.
Enhancements:
Display member SPAN data. Default SPAN color can be
set in Tools|Options|Color

BETA Features:
Note: Only available if ‘Read Loads’ is enabled in Tools|Options. With this feature enabled, the time needed to read a model may be impacted based on the number of LOAD records contained in the SACS model file. If the time penalty is too large, try setting the ‘How to Store Structural Loads’ to ‘Store as strings…’ or disable the ‘Read Loads’ feature.

Added ability to draw Joint specified displacement
loads
Added ability for user to define load/weight arrow
scale factor via Tools|Options.
Added ability to draw member loads except for
Temperature
Added ability to draw equipment loads
Added ability to draw plate temperature loads
