3d-labor
en respuesta a: rkmcswain

I think, I have solved the problem. There is a Command called GRAPHICSCONFIG to set up 3D performance settings. One of it is "Per-pixel lightning: Enables the computation of colors for individual pixels. With this option turned on, the 3d objects and lightning effects appear smoother in the viewport." I´m working with the German version of AutoCAD 2016. If I retranslate the text, wich is shown in the dialog window for this option it sounds like this: "Lightning per pixel (Phong): Increases the level of detail and the realism during working with 3d objects and lightning effects."

To be short: If I switch off the option my problem with the thick lines disappears, if I switch it on, the problem will be there again. I seems to be, that there is a relation between the thickness of these lines and the number of objects shown in the drawing, the number of open drawings and (perhaps additional) the duration of work since starting AutoCAD. In the attachment two pictures with "Per-pixel lightning" on and off (please use the 1:1 view). Hope it helps anybody who is disturbed by thick lines.
