Hi,
it' a little tricky and laborious to choose what is need to be sectioned and what not in the assembly enviroment.
(You have to go Tools>Document Settings>Modeling>Partecipate in Assembly and Drawing sections)
That for each part (ipt).
(If you have a 200 parts subassembly that you want entirely to be exluded from selection...you can image.. a lots of clicks..)
Moreover if you have the same part in different assemblies you can't easily choose different result for that part (sectioned in one assembly and not sectioned in another assembly).
It wuold be easier the ability to choose directly in the assembly enviroment what should be exluded from section, just click parts (ipt) or subassemblies (iam) , right click, and choose to not partecipate to section.
That choice and that setting will be stored only in that particular assembly.
Thank you guys!
