Assembly Arrangements - How to
Assembly Arrangements - How to
(OP)
I am a new user of Unigraphics (using NX6). I have a cabinet with a door I'd like to show in multiple positions (ex. closed, open to 45, 180 degrees etc.) on the drawing. I've read through the forums and find Assembly Arrangements are suggested.
I've done the steps to create a new named Assembly Arrangment, but now need to know what has to be done to the named arrangements to show the door different positions? I can change the active arrangement but nothing changes?
Thank you!

RE: Assembly Arrangements - How to
OK, if the position of the door is controlled by a constraint, say an angle which can be edited, what you do is first set the assembly to the default Arrangement which you've named 'Closed, and from the list of Constraints you select this angle constraint, press MB3 and select the 'Arrangement Specific' option. Now create your next arrangment, say 'Half_Open', and create a NEW angle constraint with the door at 45 degrees. Now select this new constraint from the list, press MB3 and select the 'Arrangement Specific' option. Now repeat this for the 180 degree position and call the arrangement 'Open'. Now as you switch from one arrangement to the next the different Constraints will be applied and the others will be ignored.
Now if you're NOT using a Constraint to control the location of position of that door, but rather it's free to move by dragging it, you can still make this work, but what you do then is thatyou first create all your arrangements up front, say 'Closed', 'Half-Open' and 'Open', and then making say the 'Closed' arrangement the current one, you go to the 'Move Component' dialog and in the Settings section of the dialog set the 'Arrangements' option to 'Apply to Used'. Now drag or move the component to the closed position and hit OK. Now repeat this procedure for each of the other arrangements until you have unique positions for each one.
Note that while it might appear to be extra work (having to created what at first appears to be duplicate constraints, I would recommend that you use the first procedure describe here, having a unique constraint for each Arrangement, since this will be easier to debug and it allows you to easily EDIT the position of the door in EACH of its arrangements by simply making that arrangement the current one and then editing the currently active constraint.
