Use of Status Bar and Visual reference-Ortho,Snap,Grid,Polar Tracking
The GRID option creates a pattern of lines that extends over an area on the screen. Using the grid is similar to placing a sheet of grid paper under a drawing. The grid helps you align objects and visualize the distance between them. The grid is not displayed in the plotted drawing. The default grid spacing, which means the distance in between two lines on the screen, is 0.5 inches. We can see that the sketched horizontal line in the sketch is about 4.5 inches long.ORTHO – Orthogonal drawing or rectangular drawing, it means that when you turn this feature lines that you drag the mouse will be angled in relation to the UCS and you can draw only the angle that is set and it is 90 degrees.
POLAR – Polar coordinates follow when you draw the line, if this function is activated then the Ortho automatically turned off because when you draw with the POLAR function of the mouse you can draw lines at an angle to the set and you can also set up and draw it with absolute or relative coordinates when drawing lines
OSNAP – Aiming (target) at a particular point of a line derived from activated Osnap which contains some basic positions on the line, circle, image, and the like. Endpoint, midpoint, and other sights for other points of attachment appear only when we turn Osnap mode (and turn on each target). All lines in the figure, circles, etc.. have a connecting point for the target, so to distinguish GRIP (grips) of the target.
OSNAP mod : F3 => Endpoint, Midpoint, Center, Node, Quadrant, Intersection, Extension
OTRACK – F11 – Intersetion, Perpendicular, Tangent, Nearest, Apparent intersection, Parallel
If you turn OTRACK / POLAR mode then you have an active extra dashed line that helps you draw the line to align with a line (point) to the already drawn parts of the drawings.
For setting Of above feature:
1) Right Click on Polar Tracking Icon (Visual interference Toolbar) and Click on Setting
Function key –Tips:
Using function key enhance your drawing speed.
Ex.- In drwaing when you want on or off the osnap just press Function key F3. Pressing osnap at status bar is also same.
