Draft Snap Grid

Description
This snap mode lets you select the intersection of two grid lines.

Before using it, make sure your units are set correctly,. For example,  is good for dealing with distances typical in modelling buildings;   is good if you need to model details in smaller parts; setting 4 decimals is good to consider small fractions of a meter or millimeter.

Make sure you use Draft ToggleGrid to show a grid with enough resolution for your modelling. You can change the grid properties if needed,. For example, lines at every 50 mm, with major lines every 20 lines, and 1000 lines in total is good for modelling buildings; use lines at every 1 mm if you are modelling small parts.
