Edit Surface > Enlarge 1

[itaylor]

Can I control the 'Edit Copy' option in the Enlarge Surface dialog in NX9.
If I'm reading it correctly...
The Help states that by deselecting the Associative Freeform Editing Modelling in preference then deselect 'Edit Copy' in the Dialog I can edit a surface and regardless of whether it is associated to another feature it will modify the existing surface and convert it to a sheet body. (unless it is the Face of eg... a solid, then I would expect a new feature)
I do not want to create a new feature, I want to enlarge the existing

I toggled it off in Customer Defaults (and restarted NX)

Both options add a new Elarge Surface.
I understand the logic in the command, ie if it is associated the a new feature is created, but I want to choose when it does this ... like it was in NX8.5
Thanks

It isn't always consistent.
I just tried it on a (Sheet) Body that's not associated to anything and it automatically toggle the Edit Sheet on and I cannot turn it of because it becomes greyed out.

Please don't confuse the 'Enlarge Surface' feature with the Sheet Body itself. There is still only ONE sheet body. The fact that you had toggled OFF the 'Edit a Copy' option already assured you that the original Sheet Body was being modified. You can prove this yourself by going to the Part Navigator, placing your cursor over some 'white space', pressing MB3 and toggling OFF the 'Timestamp Order' option. You will now see the 'Bodies' that make up your model and if you had started out with a single sheet body you'll still have only ONE sheet body in your model.

So when I remove parameters from the 'Enlarge Surface why am I left with 2 bodies in the tree

I use it to increase the size of the existing sheet not wanting to create a new feature. NX8.5 did it.

I don't want to use Trim and Extend because it adds new edges to the sheet.

Please note that you can now edit (as well as delete), for a period of 24 hours, any of your OWN posts, so you could have gone back and and either reword or delete your post. After posting a response and you discover something that you wish to correct, just look for the 'Edit' and 'Delete' options in the lower Right corner of your post, as shown below:

Note that this is a new feature added to Eng-Tips in the past week or so. But note that there will be a 'paper trail' showing what it is that you edited so you can't use this tool to 'rewrite history' as it were.

I'm not sure what your objective it, but I used to rely on the Enlarge command quite heavily. I model Prototype fixtures and stamping tools
I have moved away from it over the last couple of years and use Untrim, Trim and Extend or Delete Edge.
If you "enlarge" a planer or cylindrical surface, they are no longer planer or cylindrical surfaces to NX.

 

[jerry1423]

you are right, when you do an Enlarge Face that sheet body is a Bezier surface, which has its limitations.
Sometimes I can covert that enlarged surface to a planar or cylindrical surface by basing it off different surface (or face) and utilizing replace face and the distance feature within that.
