How can I change the view of the part when I add it to an assembly(Flashfit mode)?
Part is viewed as transparent with all edges visible instead of ST5 when it was just transparent.
When I add new part with many edges it result quite annoying to find right surfaces!
It is based on the current view style. In your case in the image, the view style is shaded with visible edges. If you switch it to simply shaded, you will not have the edges displayed on the transparent part while using FlashFit.
Hope this helps,
