NX6 True Shading

[jerry1423]

Every time I go into True Shading it gives me a perspective view, and I toggle it off.
Is there a way to never get a perspective view when going into True Shading?

Why would you ever NOT want to work in perspective? Even a one-eyed person sees the world around them in perspective.

Besides, the name of the function is 'True Shading'. How could it be 'True' if it were NOT seen in perspective? As far as I'm concerned, the ONLY place where working in a non-perspective, or parallel view, is appropriate is when you're placing orthographic views on a Drawing.

I guess I am one of the weird people on the planet who would rather not have it. Sometimes it just doesn't look right to me.
I have always had a minor depth perception problem, I wonder if has something to do with that.

Put me in the weird column, also. While it might make a nice static view, rolling around space trying to get work done in "prespective" view feels odd. All sense of squareness and parallelism is gone.

The vanishing point of the perspective view offered seems to be too close to the viewer, as far as I am concerned. The "un-perspective" view is more believable.....the perspective view just hurts my head.

I am with you jerry, it doesnt ever look right.

I have to admit that I'm absolutely amazed at that attitude. I've come to the point where when I open up someone else's models the first thing I do is toggle ON 'Perspective' (some of you who have gotten back models from me that you've uploaded and I've modified may have noticed this). And it's not like I've never worked in a parallel-only view of the world as I've been using UG/NX for 35 years and spent 11 years on the board prior to that. And while some of you may think this is new, UG/NX has supported perspective views since 1983, nearly 30 years (and that's about how long I've been using them). And when I hear someone say that it "doesn't look right" I have to ask; "How can a parallel view EVER 'look right' as they do NOT exist in nature?" And as for the so-called vanishing-point, that can be modified using the Camera function.

That being said, I may give some leeway to people who do NOT use a Spaceball or other 3D display controller, but if you DO, I really can't see how you think that you can be more productive using parallel rather then perspective views.

I think it may depend on how big the part is.
I work on huge mining stuff.

I have observed different kinds of spaceball users --- ones that use the spaceball to merely position the workpiece, and others that constantly move the workpiece around in space. I am in the second category; cut off my left (spaceball) hand and I would be lost with just a mouse.

Parallel views give you more information about the part. Real world parts usually have draft. Tooling is usually square or prismatic. Perspective view distorts angular relationships, hides parallelism and squareness of part features, and requires you to query the model in order to find those relaionships, and get a sense of what you are working with.

I think you are working against yourself if you work in perspective.

This is a funny / interesting thread. I'm in the middle between the weird and the normal(?)
When working I don't mind at all using the parallel projection, but if i encounter an rendered image , such as in the "Siemens calendar", where the projection is parallel i get goosebumps. (well, not that serious but it looks weird.)

But, back to Jerry's original question, is there an option to turn it off?

Regards,
Tomas

NO, there is no way to avoid having Perspective enabled upon invoking 'True Shading'. You can always toggled it OFF afterwards, but being in a perspective view is, by definition, one of the characteristics of displaying your model in 'True Shading' (again, a reminder as to what the word 'True' implies).

As a work-around for jerry1423:

Supposing the camera tool works, could the vanishing point be defined far enough away from the viewer so as to NOT affect the True Shading rendering?
