Power Trim

Power Trim can be found by clicking on the command “Trim Entities” in the menu bar.

This tool combines trim and extend. Once you’ve selected it, just click and hold down the mouse button, and move the mouse over the lines or sketch entities you want to trim.

If you want to extend a sketch line, just repeat the same procedure, but hold down the SHIFT key, so that “trim” and “extend” can be done in the same command.

The last tip is, if you make a mistake, instead of deleting everything and starting over, just go back to the red square, and your last action will be cancelled.
