symmetric modeling in NX?

Genius

Alias has a command "Symmetric Modeling":
 

Makes the selected geometry symmetric, and lets you modify the controls (CVs, edit points, blend points) on one side, while the corresponding controls on the symmetric half update automatically to maintain the symmetry. 

It seems to a special kind of constraint applied to a single B-surface. No matter how the B-surface is modified, it would keep its predefined symmetry automatically.
 
I know that some commands in NX, e.g. Studio Spline, can set a Symmetric constraint to a curve end or a surface edge. I also know that Edge Symmetry can modify a surface to make it symmetric. 
 
Is there any command in NX similar to Alias' Symmetric Modeling? Or I have not choice but to create one half first and mirror it later?
 
Thanks!

NX Realize Shape has symmetric modeling.

And of course sketches can (and should) be constrained to be symmetric using constraints like Make Symmetric.

If you don't have Realize Shape, I would create a ribbon on the plane of symmetry, and constrain my surfaces to be tangent, or curvature continous to that ribbon sheet.

Hi @MarkLawry

 

To speak frankly, I didnot find time to be familiar with Realize Shape. Currently it seems to me other commands like X-Form are enough for most Class A work. And I haven't seen similar functionalities in Alias.

 

In my current understanding Realize Shape is a special tool for artists producing originial design. Is it an essential tool for Class A workflow? Maybe I was totally wrong and missed an extremely important tool?

 

Thanks!

Hi @DaveK   Thanks for sharing! It seems that a single B-surface across the center plane can be achieved with symmetric modeling.

There is no "symmetric modeling mode" in NX but there is Mirror Display.

You can model one side first using mirror display, and when done mirror the geometry.
 Search the command finder for "Mirror display".
(  I think that a few of the direct modeling commands can do symmetric edits.)

Hi @1u7obd   OK. Mirror Display is good enough. Thanks!

Probably not yet ready for Class A workflow, but with some applications, it can be a great tool. And right within NX; not requiring any outside solution.

Here are some videos that might give you an idea.

As mentioned Realize Shape is what you are looking for. Inside that tool you can turn on and off symmetric modeling.

 

Back in NX9. Roll to the 30 second mark.
