This key will allow using Object Snap Tracking Command. While working with this command ORTHO command will automatically be shut off. This command is useful while working on objects having more than one different orientation when one part of the object is rotated 45 degrees in relation to another part. It also provides additional alignment in up and down directions.
Polar tracking will display temporary alignment paths defined by those polar angles you had earlier specified. The polar Snapping command will restrict your cursor movement only to specified increments along with the polar angles. This function key will allow the user to use the polar tracking option of AutoCAD software. By using this key, you can easily snap to a rectangular grid and create your drawing more easily and efficiently. This will allow the user to align objects and visualize distances between them. Using Grid in AutoCAD is like using the grid paper under your drawing. Grids are the rectangular pattern of dot-like structure in AutoCAD that covers the entire XY plane of the user coordinate system. This key will make a snap grid on or off. By using this mode, cursor movement will become constrained in the horizontal or vertical direction relative to the user coordinate system. This mode is used when the user has to specify an angle or distance using two points using a pointing device. This is one of the most useful keys in AutoCAD. This command will turn ORTHO mode on or off. It allows him/her to move viewpoint relative to the 2D isometric object. By changing isometric planes, the user changes his viewpoint when working in AutoCAD’s Isometric mode. He/She can make the grid visibility off by pressing this key again. The grid system allows the user to reorient him, and after that, he can focus on his design.
This function key will display grids in your AutoCAD drawing.
