WinTower/TowerDraw revision history

New features ordered by version

TwDraw 1.61

• Added support for VU-profiles.

TwDraw 1.50

• Official customer release (no new features).

TwDraw 1.41

• Place frame dialog now contains a new parameter "Plate joint". When it is selected frame horizontals are attached to the opposite chord flange faces.

TwDraw 1.39

• The structure dimensioning commands now have two settings:
  • Member length method: How the total member length is calculated:
    • Absolute: Absolute member length.
    • Bolt distance sum: Sum of bolt distances.
    • Bolt string sum: Sum of figures in bolt dimensioning string.
  • Member length rounding: How the total member length calculated with the method above is rounded to the nearest millimeter:
    • Downwards: Downwards.
    • Upwards: Upwards.
• The TWDRAW VALIDATE command now displays a report of examined members and performed fixes.
• The TWDRAW VALIDATE command now assigns new member IDs if duplicates are found.

TwDraw 1.38

• The main dialog menu now has commands for viewing the active bolt and profile tables.

TwDraw 1.37

• Changing profile size in EDIT MEMBER does not automatically change the boltline distances anymore.
• A few minor debugging messages were removed.
• A new keyin command TWDRAW VALIDATE has been added. This command will attempt to fix conflicts between the member user data and their graphical appearance. The command takes care of:
  • Element range errors
  • Flange side errors
  • Direction vector errors

TwDraw 1.35

• The "Place at bolt locations" and "Add new bolt" options are now available in the member parameters dialog too.
• The DELETE DIMENSIONS command now contains a settings dialog allowing selections of dimension types to be deleted. NOTE! Due to the lack of user data in boltline dimension texts created with version 1.35 and earlier these settings don't work well with those dimensions. Once the boltline dimensions have been deleted manually and recreated with version 1.35 the settings work.
• PLACE MEMBER, EDIT MEMBER, MOVE MEMBEREND and EXTEND MEMBER now automatically fix chord origin, direction vector and end parameters to the correct bottom-to-top direction. This is required by dimensioning and other tools that scan the chords for bodypart outer dimensions.
• Logic in body outer dimensions scanner has been improved. This should prevent software crashes when dimensioning bodyparts with incorrect number of chords in them.

TwDraw 1.34

• The member parameters dialog (command PLACE MEMBER and EDIT MEMBER) now contains item for field side parameter needed to correctly draw chords manually.
• The "Place at bolt locations" and "Add new bolt" options in the settings dialog now also work with the PLACE MEMBER command.

TwDraw 1.33

• The extend boltlines options in the settings can now be used to extend boltlines of all members in all views.
• The member parameters dialog (command PLACE MEMBER and EDIT MEMBER) now contains items for structure type and bodypart number.

TwDraw 1.32

• Edit member now works with chords.
• Dimensioning text for two washers is now configurable in twdraw.cfg.
• New tool "delete dimensions" has been added. NOTE! Due to the lack of user data in dimensions created with version 1.31 and earlier this tool doesn't delete all those dimensions. Once the dimensions have been deleted manually and recreated with version 1.32 the tool works.
• Chord profile size and length are now included in the dimensions.

New fixes ordered by version

WinTower 1.60

• Fixed some incorrect notations in result tables.
• Added guy force table into the result list.

TwDraw 1.42

• A bug preventing changing boltline positions while drawing frames has been fixed.
• A bug crashing the software while dimensioning bodyparts with deleted lower chords has been fixed. A warning and suggested fix is now presented to the user.

TwDraw 1.41

• Dimensioning of chords is now always done with the absolute member length method regardless of the method setting.

TwDraw 1.40

• A bug preventing the selection of the longest bolt during bolt dimensioning has been fixed.
• Several internal limits have been increased.

TwDraw 1.39

• The bolt dimensioning routines now search for longest bolt with matching threaded/unthreaded lengths instead of the shortest.

TwDraw 1.38

• The total length of a member in the dimensioning strings is now calculated as sum of the truncated holes string instead of the absolute member length.

TwDraw 1.37

• The total length of a member in the dimensioning strings is now calculated as sum of the bolt holes string instead of the absolute member length.
• Member cell elements are now properly range-validated to avoid "element-out of design space" -errors.

TwDraw 1.32

• All dimensions are now tagged with user data.

TwDraw 1.31

• Problem creating body cross-sections at frame location in TWDRAW fixed.
• Problem causing slightly distorted crossarm displacement in analysis module fixed.
