How do you add/remove drops while using Linear with Drop”?

Drops are added by a single left click, which is also used to turn 360 degrees while performing a linear measurement. While taking a measurement you’ll need to use a combination of left clicks and back spaces to remove unwanted drop locations i.e. if you intend to turn and do not want a “X” just hit the back-space key and continue measuring. Drop locations are depicted using an “X” and each one will be multiplied as “quantity” x “length”. The length is a variable adjusted under the take-off settings.
