I have a part that is transparent, not in an assembly, just by itself, and cannot turn off the transparency. No material is set. In the color dialog box in the Color/Image tab the pull-down with Transparent, Dull, etc. has no effect. In the Illumination tab I slide the transparency all the way to zero it is still transparent but less so. How do I turn off the transparency?
Possibly your video card and/or video card driver. What does SOLIDWORKS Rx say about your setup?
