Do you know, that… ?

In the drawings, SolidWorks, you can change the display quality of the edge mode ULU (hidden lines removed) between working a tall. According to the logic high quality should result in a better display of the edge, and it turns out, that is not always so.

therefore remember, that if the edges are not displayed correctly, sometimes you need to change the quality of the work, resulting in the resignation of the problem.
