If “Check for Updates” feature in older releases reports that there is no newer version of SCARM, download the installer directly from the website. The old release info file may be cached on your PC and it may need some time to expire. If the website also shows older version, press F5 key to refresh it.

And finally, several words about the new version.

This update brings a long-awaited feature – flex-track point-to-snap-and-join function with auto shaping of the curved part. To use it when working with flex-tracks, just move the end of the last flex-section (colored in black) over the end point (grey arrow) of the track where you want to obtain a join. If the automatic join is possible, the flex-track will be shaped with largest possible radius and a black dot will appear over the green connecting arrow (the dot is not visible when Track Heights are shown). Click with left mouse button to set the connection. See how this works in the demo clip below:

The new automatic feature is 100% precise and accurate, but for now it can handle only simple curved shapes. If you need a flex shape with change of the curvature or direction of the curve, do this manually and use the automatic function on the final stage. The old way of manual joining is still working as before. It allows some tolerances in the connections and you can always use it together with the new automatic feature.

This version also comes with the ability to work with mixed gauge (standard and narrow) track systems, new and updated libraries and many other small improvements. I hope that you will like this release and also hope that the next version will be ready in the beginning of the autumn :)

If you like SCARM, share the info about it with your friends in the social network sites or post a link to in your blog or your favorite railroad forum, so more and more model train enthusiasts and fans to know about it and to use it for free.

  1. Hi
    In Your 0.9.21 release notes I found this:
    Bug fixed – Integer Overflow
    However I just downloaded and installed 0.9.23 beta and I get error ‘Integer Overflow’ anyway.
    I use Roco Line (HO) and are trying to connect a small (ca 235mm) of flextrack (F4/Wood) to fill in the gap between track/sections.
    I get the error when I get too close (ca +/- 10mm) within the track i’m trying to connecting to (rightclick/autoconnect).
    Is there a fix to this ?

    Great product !

  2. It seems that the new bug is different, related to the flex-tracks shaping, but with the same error message. I am already working over it and the error will be fixed in the next release of SCARM :)
