What happened to reposition in NX 7.5?

[grykon]

When moving solid bodies and/or components, reposition was an invaluable tool, especially being able to move objects from one origin defined by xyz coordinates to another. What happened to this function? Why would it ever be eliminated? It is crucial! I have worked with software engineers/programmers before, and I understand that they feel the need to change/fix things that don't need to be, case in point....transfer/move being split up, but this one baffles me.

That is what CSYS to CSYS is.
It is available on Move Object and move component.

In Modeling select the Component / MB3 / Move... / Select "Dynamic" under Motion

This will allow you to move components like Reposition did in earlier versions.

 

[Toost]

Joycejo is correct, the change is the name, Reposition -> Csys to Csys. Probably due to the name conflict with the "old move component" which also was named "Reposition".

- Hm, did the guys developing either function actually run anything else in the system ? Guess not.

How is a person going to be able to duplicate "transformation -> 3- (or 4-)point fit", with the "move" command? I must be missing something.....is there a "point fit" in the new, wonderful "move" command?

It would be a regression if "transform" is canned, without "move" having this capability...

At the moment there are no plans to replace the 3- and 4-Point Fit functions with Move, which is one reason that we've left those functions on the old 'Transform' list of functions.

To an Engineer, the glass is twice as big as it needs to be.

Just when I want to use Transform > Point Fit > 3-point fit, I get these errors:

1) when I try to move the body, I get "Cannot apply non-uniform scale to bodies. Choose OK to continue ignoring bodies"......which after choosing "OK" does diddly.....

-and-

2) when I try to copy the body, I get "Transformation type is unsuitable for highlighted object"

Is this a regression? Why the two different error answers?

NO, this is NOT a regressions since you've NEVER been able to apply a 3- or 4-point fit to a 'body' (go back to something like NX 5.0 and give it a try). This type of Transform is limited to curves, points and other non-topological objects.

The transform options help page refers to transforming "objects"........is a body not an object? I am not convinced......it lets me select a solid body...................then complains (with 2 entirely different excuses) about not being able to do anything with it! Sheesh!!

I used to use transformation, 3-point fit all the time in NX2-3......did I miss the regression? Can you show me any documentation that definitely says that transformation, 3-point fit does not work with bodies??

....or must I resort to 4-point fit to reorient a solid body?

Sorry, but that's the way 'Transform' has worked as long as I can remember (and I've been using UG/NX since 1977).

Look at the "point fit transformation overview":

~UGS/NX75/UGDOC/html_files/gateway/index.html?goto=search/qagent_highlight.html&vars=-aux,-home


It shows an example of 4-point fit on a solid body, albeit scale and no re-orientation.

And I've been using UG/NX since 1982.

Are you saying I can't "point-fit" repososition a solid body?

That is a regression. The help file is my witness.

[capnhook]

I have the sneaky suspicion that 3- and/or 4-point fit transformation of solid bodies has been secretly disabled......a regression.

We have provided you with what is now the preferred scheme for repositioning with 'Move Object' using 'CSYS to CSYS' with one of the options to define a CSYS is selecting an 'Origin, X Point, Y Point' (i.e. 3 POINTS).

However, I must apologize and retract part of what I stated previously. The 'Transform' 3-Point Fit should still work for a body (I just verified it using NX 7.5) however, it was the 4-point fit which was not designed to work on topological objects (i.e. Bodies).

If you wish to perform a non-uniform scale of a body you should use...

Insert -> Offset/Scale -> Scale Body...

...and select the 'General' Type of scale.

Sorry if I contributed to the confusion surrounding what is still available using Transform versus Move Object.

That makes no sense. This operation has undergone a sneaky regression, I'm sure of it now.

1) I remember using 3- and 4- point fits on bodies, at least back to NX2/3. Worked every time.

2) The help page that I referenced above CLEARLY SHOWS A BODY undergoing a 4-point fit, transformed and scaled. Is the help file incorrect, too??


I will attempt to "move > csys to csys". I hope I am pleasantly surprised that it works.

I am pleasantly surprised it works. Took me all day to figure it out, but it works.

The old way does not work anymore.

I went back and tested the 4-Point Fit using UG V17.0.2 (released 11 years ago) and this was the message that I got:
