Question

Assembly Level Cuts - Good or Bad?

I would like to get feedback from the community on the use of assembly level cuts. The pros and cons, the hidden dangers, etc. I have been trained from one perspective, but I am interested in hearing the opinions of others. I am familiar with copy geometry, publish geometry, skeleton models, top down design, etc. Thanks.

Behind the scenes an assembly level cut is creating family tables to turn the cuts on and off at the part level. The family tables are hidden from the user and there is no way to see them. I know this because in one of the versions of Wildfire I had one fail on me and it opened up the hidden generic. I asked PTC about it and they confirmed this is how it works.

Every time you make an assembly level cut you double the number of components in session because of the family tables. This is what decreases the performance.

    I can confirm this, having had basically the same conversation with some PTC engineer. It creates hidden family tables in every part intersected.
