Distortions in nXt renderd AutCAD Architecture Curved Walls

Please see the attached images.  

In AutoCAD Architecture's native renderer, and in its 3d display, the curved walls appear smooth.  In nXt the materials are uneven (with sometimes extra lines that protrude from the walls).  Distortions also appear in straight walls which should be flat and smooth though the problem is less pronounced.  

I tried changing the material definitions but the problem persists.  

Could this be some sort of scale definition issue?

The problem persists with all the rendering engines (standard path and hybrid).

Any help on this would be much appreciated.

This is typically a units problem or a coordinate system problem.  Check the units by typing _DDUNITS at the command line and looking at the insertion units.  If they're correct, make sure the model is not located too far from the origin.  Coordinate systems such as "state plane" will not work correctly with nXt-- the model will have to be moved closer to the origin.

Yes, Roy, the units were correctly set but the model was very far from the origin (forgot about that issue).  Looks fine now.  Thanks very much for your prompt reply.

"Another good rendering. Those two photoshopped reading lights are not looking good though. They don't follow the perspective, the left one is higher than the right one. Also, they are supposed to be turned on (judging from the light on wall…"

"Great image as always. I would just blur the tree shadow on the lawn to match soft shadows on the building. Nice blending of cut-out greenery. Excellent job."

"Very nice rendering Chris! The only thing that distracts me is the fruit bowl. It's too evidently pasted in PS.  Another thing (nothing to do with rendering) is the microwave above the stove. I would rather expect a cooker hood there."

trim and extension command

On AutoCad 2021.The trim and extension command works funny. I initiate the command then click the cutting edge (press entre) then click the lines I need to trim or extend.Now I initiate the command and as soon as I click the object selected trims or extend.  How can I correct this, it is really affecting my work?See More
