SusProg3D - Suspension by Design.
===================

Windows 7, Windows 8, Windows 10

Version 4.630B (Build 1190.1)

Updates and fixes in this release.
=================================
V4.630B (Build 1190.1)
Double clicking on a data file now always loads the correct file.
The intermediate link steering now allows the intermediate link arm to extend opposite to the Pitman and idler arms.
The chassis pivot Mumford linkage now allows for

1) the bellcrank and lever pivot axes P2 can be offset laterally and vertically,
2) the bellcrank and lever pivot axes can be different lengths,
3) the bellcrank and lever chassis pivots P1 can be non-symmetrical.

The axle pivot Mumford linkage is still restricted to

1) the bellcrank and lever pivot axes P2 must have zero lateral and vertical offsets,
2) the bellcrank and lever pivot axes can be different lengths,
3) the bellcrank and lever chassis pivots P1 can be non-symmetrical, but must have the same longitudinal dimension.


V4.630A (Build 1184.0)
Minor updates to the recirculating ball type steering Pitman and idler arm descriptions.
Extended the Mumford linkage to include axle mounted bellcrank and lever.
Added an error message if the rear ride height reference point is forward of the front ride height reference point.
Excel 2016 (V16.0) now correctly identified.

V4.620C (Build 1173.2)
If the roll and/or bump increments are zero, then default them to the max bump or max droop.
If the Pitman arm and/or idler arm axis is tilted (in front view) the steering calculations can fail.

V4.620B (Build 1168.1)
Added the roll direction for Dynamic calculations.

V4.620A (Build 1166.0)
Added an option to the 4-link live axle to have a birdcage linkage on one side.

V4.610A (Build 1159.0)
Fixed the download link in the About box.
Refactored the Excel import and export code and corrected a number of bugs.
Added strut data to the Excel import and export.
Updated the Excel help file documentation.
Fixed a memory allocation bug.
Fixed an issue that caused the rates calculation to fail if the steering calculation had not been done, or raised an error.
Fixed a bug that sometimes caused the spring wire diameter to become very small.
Changed the spring symmetry test to exclude the position of the spring platform.
Fixed the torsion bar windup angle calculations.
Fixed a bug that caused the torsion bar class to increment with successive calculations.
Updated to the latest Delphi 10.2.3 Tokyo compiler.
Fixed a bug with the chassis caster link mount for Ford Mustang.

V4.605A (Build 1137.0)
Fixed a bug in Sawdust that prevented updating the number of licences.
Refactored the Excel import and export code and corrected a number of bugs.
Added the error logging to all Excel tools.
For metric data, added the functionality to the Excel tools to handle "inch size" wheel data.
Updated the Excel help file documentation.

V4.600E (Build 1131.4)
Fixed a bug that prevented setting the chassis camber link mount for Ford Mustang.

V4.600D (Build 1131.3)
Opening a data file with live axle sometimes fails if the toe setting is non-zero.

V4.600C (Build 1131.2)
Opening a data file sometimes fails if the TotalMass is zero.

V4.600B (Build 1131.1)
Opening a data file fails if the roll calculation start is using a "bump" point.

V4.600A (Build 1131.0)
If the wheel toe setting option is changed, any open dialogs will now be updated with the new setting.
If the angle setting option is changed, any open dialogs will now be updated with the new setting.
Added the front wheel steering to the display.
Removed the hard limits on the number of bump & droop calculations.
Removed the hard limit on the number of roll calculations, and now roll in both directions.
Changed the Ackermann calculations to use toe-out-in-turn instead of using the steering arm intersection.
Added Ackermann percentage to the Excel exports.
Added steering offset to both steering calculations and Excel exports.
Added an option to limit the Excel ranges.
Added the pushrod/pullrod to bellcrank angle, shock to bellcrank angle to the suspension calculations, and added them to the Excel exports.
