How to Set a Running Object Snap in AutoCAD 2014
Every object type in AutoCAD 2014 has at least one point, such as endpoints, midpoints, or quadrants, and you can snap to them precisely as you draw by using object snaps (osnaps).
AutoCAD provides two ways to use an object snapOften, you use an object snap setting (such as ENDpoint) repeatedly. Use running object snaps to address this need.
Follow these steps to set a running object snap:
Right-click the OSNAP button on the status bar.
The Object Snap menu appears.
Many status bar buttons display shortcut menus when you right-click. (Object Snap and Object Snap Tracking both display the menu of running object snaps.) Many settings, including all running Object Snap types, can be set by clicking a menu item. You no longer need to open the Drafting Settings dialog box, make your settings, and then click OK to close the dialog box.
Click in the menu to select one or more Object Snap settings.
Active running Object Snap settings show a highlighted square around the icon.
You click the Object Snap button on the status bar to toggle Running Object Snap mode. After you turn on this mode, AutoCAD hunts for points that correspond to the object snaps you selected on the Object Snap button’s right-click menu.
As with object snap overrides, AutoCAD displays a special symbol — such as a square for an ENDpoint object snap — to indicate that it has found an object snap point. If you keep the crosshairs still, AutoCAD also displays a tooltip that lists the object snap point type.
Use object snap overrides or running object snaps to enforce precision by ensuring that new points you pick coincide exactly with points on existing objects. In AutoCAD, you can’t let points almost coincide or look like they coincide. You lose points, both figuratively and literally, if you don’t use object snaps or another precision technique.
For example, applying crosshatching rapidly becomes impossible if the boundary of the area you’re hatching has even microscopic leaks.
Most, but not all, object snap overrides have Running Object Snap equivalents. For example, ENDpoint, MIDpoint, and CENter work as either overrides or running object snaps, but Mid Between 2 Points works only in Override mode.
