Parametric transform
Parametric transform
(OP)
Hello,
I have a "dead" non-parametric geometry, which position I want to parametrize whenever some other object(Sketches, lines, datums etc.) changes position. I want to that in a single part.
In general I am taking dead objects and putting them in model that needs to be parametrized. Thus the dead object need to move as well.
How do I do that? Transform operation is not bounded by other objects' position.
Please, advise.
I am working in NX4.
Greetings,
Tish

RE: Parametric transform
I think that will do what you want, and it will be parametric.

Insert -> Direct Modeling -> Constrain Face...
...you can basically do what Jerry suggested earlier.
First choose the type of relationship (Constraint Type) that you looking for and then you select a 'Seed Face' as your first selection . When you're asked to 'select boundary faces' simply select the rest of the model using area select. Now skip the next step (whether there are blends or not is irrelevant in this case) and then select the face on the body you're constraining that you wish to constrain relative to the face on the body which you wish it to be associated to based on the type of relationship (constraint) that you initially picked.
Once established, these constraints will cause the first body to move whenever the second one is moved or the size is changed due to it being edited and the faces which were referenced are moved. If you're creative you can emulate many of what are now called Synchronous Modeling techniques only you don't have the better interface nor the smart selection.

RE: Parametric transform
Constraining the face does the job. Just for the record I have a second solution.The command is called geometry instance. If you constrain the end point of a line with the parametrized object, you can use this end point as a reference for the Geometry instance command. Of course the initial object(the container) needs to be sent in a hidden layer and its instance to be used instead.
Once again, thanx for the good discussion ;).

Fatal error detected, unable to continue.
I am happy to know that I can crash NX everytime I want. This gives me some advantage in the modern computer world. I can still crash them not they me.
In reality the job needs to be done and there is no place for having this sort of fun :)

The upgrade is planned for the end of the year.
