Z Clipping 1

[Befuddled]

Can anyone please explain how to set up z clipping in NX

Cheers

What version ?

In any view there is a box size dictated by a distance in front and to the rear of the view and centered approximately half way in between. The Z-clipping as you describe it does not appear to exist.

This is a whole lot easier to do starting in NX 5 with the new 'Camera' function.

Agreed, but the post doesn't even state whether it refers to a drawing view or a model view which is now also a model camera. I believe the two terms view and camera to be equivalent in modeling as far as I can tell. Please correct me if I'm wrong.

Also the idea of a Z-clipping plane as opposed to just front and rear is not something I am familiar with, so I'm looking to be contradicted if it actually exists.

The version i need to currently perform this action on is NX2.

In a ideal world i would like to do this in a drafting view, but if it could be done in modeling, that would also be of benefit.

Edit the View Style and go to the Perspective tab.

Which gives you front and back clipping planes. So if your view looks along the Z axis in absolute there is an interpretation whereby you may be in luck.

By definition, in Drafting ALL views "look along the Z axis", so adjusting the clipping planes is adjusting Z-Clipping. The term Z-Clipping does NOT refer to the X,Y,Z axis of the modeling space, absolute or otherwise, but rather the front and rear clipping planes of the VIEW looking along the axis of the view no matter what that might be relative to absolute space.

John,

Yes okay that is another interpretation that could be what the question meant the view WCS would be created with Z pointing in and out of the screen. You still have to call them front and back or you'll never find them in the dialogs which as Phil rightly points out is under the perspective tab.

Does some other CAD system refer to the clipping planes using terminology like "Z clipping" in their jargon? You had me thinking of clipping relative to the co-ordinate system rather than the view. I had the sense of something you can do with dynamic sectioning but not with clipping planes.

Sorry if anyone was more confused that I myself, and I hope we ended by helping anyway.

Cheers

Z clipping is a computer graphics term that did not originate with CAD, nor is it exclusive to CAD. John gave the correct definition, it is not simply 'an interpretation'. When programming 3D graphics, you have absolute coordinates (acs), local coordinates (wcs), and screen coordinates (the screen is always considered the X-Y plane). Z clipping refers to the screen coordinates; you have to take the 3D geometry and project it onto a 2D screen; the z clipping refers to the front and back cut off distances.

Well there you go I just never heard of it before. Must have missed the meeting on that one I guess. He had me thinking a whole other scenario.

Thanks Cowski .
