Guess we have to model it from scratch again
1. Download , install and use 30 day trial version of 2013
2. Flaten panels in 2012 version ie by addin attached (corrected version of previous one) and correct the worst panels (replace them by triangles), connect them properly (do noy use kinamatic links)
(model sent to you in PM)
3. Remove panels, leave bars, basing on bar nodes \ nodes create trianglar panels.
