The SelBrush command selects objects based on painting a thick brush stroke.

### **Steps**

  By default it uses crossing select: objects touched by the stroke are selected.

  Use Selection Filters to change what types of objects/sub-objects are selectable.

* **InvertCrossing**

* **Yes -** Selects objects/sub-objects regardless of their visibility.
