SolidWorks is full of little options and commands that we often look past or gloss over. In my experience, one of these commands is Invert Selection.
Let’s say you have a twenty-part assembly and you want to hide all of the components except three; an easy way to accomplish that is to select the three you don’t want to hide and do an Invert Selection, then click the Hide command. The steps are as follows:
Step One: Select the components you don’t want to hide.
Step Two: Right-click and choose Invert Selection from the pop-up menu.
You now have reversed the selection set: the items that were selected are no longer selected and the items that weren’t selected now are selected.
Step Three: Right-click again and select Hide
There you have it! All but the three originally selected parts are hidden.
