Automatically constrain objects being drawn - AutoCAD

Question

Can I automatically constrain objects as they are being drawn?

Answer

You can automatically apply geometric constraints while creating and editing geometric objects, to enable the inferring constraints function either select “Infer” on the status line or use the key combination of CTRL + I, constraints will automatically be applied between the object you are creating or editing and the object or points associated with object snaps while this function is turned on.
