SusProg3D - Suspension by Design.
Version 4.661 has a number of enhancements.

Thanks to all of those who made comments and suggestions.

In no particular order.


Updated all calculations to ensure that all pre-requisite calculations are called in the correct sequence.
This now means that when doing any of the spring, shock or antirollbar calculations then the full geometry calculations (static, roll&bump and steering) are always done.
Previously it was possible to skip the steering calculations which then led to some inconsistencies in the motion ratio calculations which then impacted the wheel rate calculations.
In a perfect situation with zero bump steer excluding the steering calculations had no effect, but as the amount of bump steer increased this effect was more pronounced.
Both eCalc and vCalc have been updated correspondingly. So now, there is no difference in the calculations performed whether called from eCalc, vCalc or the main menu commands.
The only exception is that the driveline calculations (where applicable) are not automatically included with any of the springing calculations


When doing the Rates calculation, if the spring rate is set to "Frequency" the new spring rate isn't calculated. Fixed.
It was while assisting Rob with his project vehicle that uncovered this issue, and also identified the need for performing all the pre-requisite calculations in order to maintain consistent results. Thanks to Rob.


Fixed a bug in the spring, shock, arb suspension input form that displayed incorrect text.


Fixed a bug in the display control form that sometimes showed an incorrect wheel toe description.
Thanks to Jan for this one.

Your feedback and suggestions are always appreciated.
