Selecting Representations AFTER selecting model in IPN

[skotzur]

The machines that we design have many moving parts. Our policy is to have all parts that can move in the real world also move in the master positional representation. Doors can open and close, pneumatic cylinders can extend and retract, tables on rails can slide up and down, wheels can turn, etc. These motions are typically controlled by a constraint with limits and certain sub assemblies will be given flexibility as needed. Parts that can move do move at every level of our assemblies.

If a particular configuration is required for a drawing view or .ipn then a positional representation will be created certain constraints will be modified or added (and suppressed in the master) but enabled in the positional representation to achieve the required result, all the while adhering to our policy of  leaving the master positional rep free to move as it does in the real world. If you do not select one of these "static" positional reps for your DWGs or IPNs then when pieces move in the master representation of the model they will also move in the views you have created. It can wreak havoc.

When placing a new view in a .dwg file you have the option to select a positional representation. If you forget to select that positional representation you have the opportunity to select it after the fact by double clicking on the view and selecting the desired Representation from the drop down list:

That's great.

Similarly when inserting a model into an IPN you can select the desired representations by clicking the "options" button:

Also great.

The problem is that once a model has been placed in an IPN you can no longer adjust the positional representation. This means that a drafter may do a fair amount of work in the IPN with it in the master positional rep. Everything in a particular position but then because the model is dynamic and flexible in the master, if anyone ever moves something it can wreak havoc on the views! There is no way to change the positional rep after the fact as far as I can tell:

See the below example:
