I find that whenever I try and do a truss optimization like your example (modified gh file posted below) and include the cross optimizer my grasshopper crashes. Do you have any idea why this is the case? Just wondering why the croSecOpt fails so that I can prevent it earlier in my GH file. I tried only allowing it to run when displace and utilization were low, but it still seemed to fail.
Any help would be appreciated thanks,
