dynamic views

  duct branch not displaying

  cached file centrelines change to ls=2

I think I am finally getting there with dynamic views using Aecosim SS6 but there are still some problems:

A)  Ductwork branches and square to round fittings are not displaying in some files

B)  I am having the cache the dynamic view model in order to plot it to a reasonable size. When I do this the symbolisation of ductwork centrelines goes from ls=4 to ls=2

Is there any project configuration adjustments that would help with either of these problems or any other suggestions
