When opening CAD system, the system creates a new empty drawing, we can see in the drawing there are points(in lower version of CAD) or lines(in higher version of CAD) that are equidistant from each other, which is called grids. So what’s the use of grids in CAD. OK, let me explain this in detail.
Drawing with coordinates and grids ensures accuracy. But sometimes we’ll need some feature points of given graphics in the drawing. Coordinates of those feature points such as endpoint, midpoint, intersection point are unknown, nor are they on the grid points, then how can we locate those points? Don’t worry, with the Object Snap in CAD, we can easily locate to those feature points, it’s a commonly used drawing tool and therefore it’s very important to know how to set and use this tool, especially for beginners.
