Dumb solid associativity to apoint

[venomex]

Is there a method to rotate a dumb solid part about a pivot by associating the rotating end to a point, such that when I move the point about a arc traced the link/part rotates.
P.S : I don't want to manually rotate the part by associating pivoting end to a 3d point.

Thanks

First off, what version of NX are you running?

Second, by definition, a 'dumb solid' is just that, DUMB, so while you say that you "...don't want to manually rotate the part by associating pivoting end to a 3d point." you're probably going to have to associate something with something.

We are using NX9.
Yeah as you said I got the dumb solid on which I am supposed to work if possible( else I have to create a parametric model of the same).
So yeah I was thinking of associating a 3D point to the part and was trying to give an expression to move the point, but I realised I was not able to select the 3D point in the expression.

Also, I created a parametric model with my futile attempts at DUMB solid. but I encountered a problem in expression part where rotating the part at given point kind of deformed the part( though part was fully constrained). But strangely when I give tangency constraint to the same it worked like a charm but dimensions were changed/altered.Any insight on solutions

Thanks John.

Do you have to use a 'point' to move the object? Couldn't you just use a series of 'Move Object' operations, as I've done in the example below, that will allow you to move and rotate a dumb solid in any combination of X, Y, and Z moves as well as rotatations about the X, Y and Z axis. Just open the part, and then go to the Expression dialog where you will find expressions to control the location and angle of the solid body.

Do you have to move the part geometry itself? Can you add the part as an assembly component and use constraints to get what you need?

Try to use Edit --> Move Object Turn on Associative and off Move Parents. Use point to Point or CSYS to CSYS

Have Fun

@ John
I would have used expressions as showed but I am working on an assembly and I need to associate or keep the parts connected without using assembly constraints.

@cowski and @ csbk
Sadly, I am not allowed to do that, we have to use expressions as we are creating a template.

I do not know if you can do this or not but have you tried using move faces using the synchronous tools?

First off, why are you not using Assembly Constraints? If the 'dumb' solids are Components with their own part files, then Assembly Constraints is about all that you have.

Now if the 'dumb' solids are in the Assembly file itself, not as Components but as simple bodies, then you could use the 'Move Object' function and an associative 'Point to Point' move where you reference a point on the 'dumb' body with a point on a Component of the Assembly. Just toggle 'Move Original' ON and 'Move Parents' OFF and it should work.

@SDETERS
No, it won't help me...

@John
Yeah, this seems to get the job done.
Thanks a ton all...
