Faceted visualization

[cubalibre000]

Hi,
we have refiled 125000 part.
We load components with this setting in the 'Assembly Load Options'
- Use partial Loading
- Use Lightweight representation
- Load Interpart Data
- Enabled in the customer default 'Load Smart Lightweight Data'

The result is like the image attached.
All my colleagues are asking me why this visualization and they don't like.
Without lose in performance or reduce to minimum increase, there is a solution to transform a cylindrical face in a better visualization, not like a n-polygon face ?

Thank you...

This IS the correct AND EXPECTED behavior. This is what happens when using 'Lightweight Representations'.

What you are seeing is the so-called 'faceted' representations of the components edges and faces as started in each part file. They are NOT being computed by the graphics engine and therefore will result in both improved load time, memory usage and lastly, improved graphics performance since there is no longer any need to compute the data needed to convert a solid/surface model into something which can rendered as a shaded model using either software or the firmware of the graphics hardward. The tessellated data is already there and only needs to be displayed as such. If you were using 'Exact' representations then while it might 'look better' that would ONLY because the local display settings were such that a finer tessellation wwas being used than what was used when the 'lightweight representations' were created in the individual part models now represented as Components in the Assembly. However, those local tessellation would have to be created at the time the assembly was being displayed and would also have to be recomputed whenever the display of the Assembly is changed and the view scale is updated. This is no longer needed when using lightweight representations.

Now it is possible to go back and change the tolerances used when creating the lightweight representations in the original component part files so that this 'faceted' effect is reduced, but this will somewaht defeat the purposes of using lightweight instead of exact representations at the Assembly level. The whole idea is to use a level of VISUAL approximation that is acceptable while gaining the maximum increase in VISUAL (and system) performance when working with large and complex Assemblies. It's just a matter of getting used to the fact that representations, while perhaps less visually pleasing, does provide for better performance and has NO real impact on the quality of your models or even the Drawing or renderings which might be produced as the 'products' of your effort.

Hi John,
what you have wrote, it's known by me.
I've implemented myself all NX8 setting, customization and decision in our company (30 users), but however the changes in the established method must be clarified.
It was done by me, but my colleagues want a Siemens explication and what you have wrote it's perfect.

Thank you.
