Ad a box somewhere where you can see what there is been selected.
So if i wille extrude something, i will see the regions that i have selected.
Or if i want to patch a surface, i want to know witch lines i have selected.
Now, I can only see the lines or regions highlighted. But sometimes there are so many line or regions (especially with skeletal modeling) then i can't de-select some lines or regions i don't want to use. With the box, you can deselct them from the box. 🙂
The box can be just like:
Line1
Line2
Line3
etc...
OR
Sketch region1
Sketch region2
etc.
And yes, Solid Works has it... It works very well!!
