How can you tell if a component has been moved. 1

[JurgenKreisel]

Is there a way to find out if a component has been moved?

We usually build our parts in place and do not move them in the assembly. But it does/has happened that a designer has move the component. I can remove the component and put it back in again at absolute zero but any wave links created from this part will be broken.

Is there an easy way to have the component moved back to it's original build location within the assembly after it has been moved?

Thank you in advance.

Hi,

There is no way to do that. The best solution is to add a fix constraint on each component.
So, I have a question to John Baker:
Did you have a programm to do that because the fixed constraint doesn't accept the rectangle or all component selection ?

Re-add the component to the assembly, making sure the setting is set to add at absolute zero.

Re-add the component, just to verify the location, if all looks good, delete the added component and don't save the assembly. That is probably your only course of action.

To easily tell if a component has been moved, choose Information -> object on the component. In the information listing you will see translations and a rotation matrix. If the translations are 0 and the rotation matrix is
1 0 0
0 1 0
0 0 1
The component has not been moved.

To get back to the original position, make the component the displayed part, position the WCS at absolute, save a copy of the WCS and add it to the reference set used in the assembly. Make the assembly the displayed part and position the WCS at absolute. The difference between the 2 coordinate systems is the amount the component has been moved. You can perform a move component, CSYS to CSYS to move the component back to its original position.

An alternative, probably simpler, solution would be to add the component again at absolute and use it as a reference to move the existing component into the same position as the newly added one, then delete the extra component when you are done.

Attached below is a zip file with an NX Open program (the .vb source and the complied .dll) which will add a fixed constraint to all Components in an Assembly which are not already constrained in some manner. When downloaded, edit the file extension from '.zipper' to '.zip' before you attempt to extract the files.

Thank you to all who have replied to my question.
I will ask GTAC to open an ER to be able to move a component back to its original build location.

Here is a journal that will do it.
It is meant to be used on a component that has been repositioned in the assembly, not one that is positioned using associative assembly constraints.
