When you run an edit command you have to select the objects that you want to edit.
There are a few ways to select objects:
- You can click one by one the objects you want to select.
- Crossing method. With this method you have to set a rectangle by setting the two opposite corners of the rectangle. Then all the objects that are included entirely in the rectangle or have an intersection point with the rectangle, will be selected.
- Window method. Similar to the crossing method, but only the objects that are included entirely in the rectangle will be selected.
