I use SW2015 and would like to use "tree house" for my hierarchy tool and when using it I get  an error on larger assemblies. I also save/export the tree's that do not blow up and I can't open them (.asmtree) is it's extension. although it asks for a model/format to use in making the tree of export. Can some one help me make this a useful tool to any level except for a screen shot that's basically useless.
