Dynamic sub assemblies .. are they coming???
Message 1 of 12
One of the disenchantments of sub assemblies is that they lock up when used!
Common to most CAD systems with a few exceptions.
So I ask, (hope - big wish - really really want) - will 2013 have dynamic - working sub assemblies?
If so, how many levels ?

I am very interested in "Dynamic sub assemblies" what you really need it. So for your viewpoint, how to understand " Dynamic sub assemblies", could you give me more detail and describe.

OK - easy.
Lets say I am building a car.
I am working on the suspension.
It has components(single parts) and sub assemblies(parts assembled but inserted as one item.).
A shock absorber is an example of a sub assembly.
It is made of multiple parts and has a motion range - compressed to extended as defined by it's assembly constraints - and allows rotation between top and bottom fixing points as it is unconstrained in rotation between the upper and lower parts. So, some constraints and some degrees of freedom (DoF) remaining.
When the shock absorber assembly is inserted into the suspension it becomes a sub assembly between the shock mount points and we want it to control the range of motion of the suspension or at least be free to move as assembled.
Dynamic Sub Assembly is this management of constraints and DOF's across levels of sub assembly that allow the movement to occur.
Will it still be allowed to move as defined within the range of it's own assembly?
I hope that explains it OK.
Ask for more info if this is not clear.
Cheers - Paul:)

what would that do for you? e.g how would you use that?
Explode/configuration kinda does that now.
What I would like is the same constraint naming structure in the history as there is in animation. Something I have asked fro a long time but it seems others just know which constraint is which - well I don't.
I also want a choice for Edit constraint to either change the original constraint or make a new history feature (as it does now).

often, I want to look at one part of the assembly by being able to move it in a partially constrained condition (turn off just one constraint and drag parts or a group of parts around to view the impact. Turning off just the constraints that that prevent the kind of motion I want is convenient. Turning them back on should automatically reposition the parts I moved for test.

you can do that now with Assy Config recording.
Record a Config - e.g current one. Then edit constraints for a part as much as you like. Record that Config, then re activate the original. (or something like that) Once you are finished experimenting you can either just carry on or delete the experiments.
Time to read the Help some more....!

I know that we have some developed project for assembly. For example,all the sub assembly not just shows as a rigid part, the top assembly can insert the bottom parts from the sub assembly even it's the bottom level, also we can more easy to manage their constrains.
Regarding your request, I still need to get the future version for testing and tell you the effect whether it achieve your request.
