Note:- Any Duplicate files contained in any of my script packs can be used. Just ensure you copy the latest version of any file. These script packs are being built up using some common utility type scripts which are shared across more than one pack.

Version 1.1.0
Modified Script to improve curve building when using Sprockets of two sizes which are very different in diameter.

Description Section

The Scripts will build Dimensional accurate Metric Chains using the relevant ISO Standards and the GUI will show the English Equivalent during the setting up of the vrious options.

Usage Section
Type DVY_Chains in command line or middle mouse drag it to a shelf. There is an Icon file supplied to use with the Shelf Button.

The Metric Chains manufactured to the above standards are covered by ISO 606 and DIN 8187.

These standards cover 3 versions:

The range of pitch sizes can vary between 4mm, (0.158 ins) to 114.3mm, (4.5 ins).

American standard chains are covered by ISO 606, ANSI B29.1 and DIN 8188
and eight versions are covered.

** SIMPLEX, DUPLEX and TRIPLEX as for the European standard chains.
** QUADRUPLEX, 4 strands.
** QUINTUPLEX, 5 strands.
** SEXTUPLEX, 6 strands.
** OCTUPLEX, 8 strands.
** DECUPLEX, 10 strands.

The pitch sizes covered by this standard are 1/4 to 3 inch pitch.

For Metric Chains above TRIPLEX these are normally classed as Custom but these Scripts will build the relevant number of Strands using "Standrd" metric Sizes and Specs.

The scripts will build two Sprockets (plus Idler Sprocket if required). Once built the second sprocket position can be adjusted before building the chain. The chain length is set to an even number of Pitches and this is done by auto adjusting the second sprocket by a minimum amount to achieve this. After building the chain the Idler can be adjusted for position before rigging the scripts. After rigging the default speed is 1 RPM but this can be adjusted as required and set to reverse direction. Also Sprocket rotations can be adjusted before and after rigging to ensure correct tooth and chain meshing/alignment.

See Readme file for detailed usage instructions.
