Improving presentation quality for 3D models in Navisworks 2013.

A - answer Autodesk Navisworks 2013 (and 2012) offers two graphics systems (drivers), using the graphics system "Presenter" as the default (resp. the option "Auto-select"). But the unified graphics systém "Autodesk" based on DirectX (similar to other Autodesk products) offers higher display quality for your shaded 3D models.

You can switch graphics mode with the Options Editor dialog (N > Options). In the option tree Interface > Display uncheck the option "Auto-select", switch the selection System to Autodesk and check the option "Occlusion Culling".

In the tree Interface > Display > Autodesk (2013 only) then switch "Shader Style" to Phong shader and check the checkbox "Screen Space Ambient Occlusion". Confirm the options with OK.

The display mode of your shaded 3D model will change from the original:

to a higher quality mode:

(depending on the hardware acceleration on your graphics card, the display performance may be lowered)
