I lost the function of the edges in shaded image mode and despite my temptations, it was impossible to see this display mode again
The most fun thing is that it started from a sub-assembly and as soon as I insert it into another, the mode disappears in favor of the shaded image mode!!
I've never had this problem, but it doesn't come from the fact that the shutdown takes too many resources from the PC and for Solidworks to continue to work well?
In fact I know, it's because the complex assembly mode is activated: if the assembly has more than 500 components by default, to free up memory it is impossible to display the edges in shaded mode!
Right-click on the assembly in the tree and disable the complex assembly mode, or
