1. A surgical system for facilitating surgical planning, the surgical system comprising:
a digitization device comprising a pointer tip and one or more control inputs that are configured to be actuated;
a navigation system configured to track a state of the digitization device; and
a computing device coupled to the navigation system and comprising one or more processors and a non-transitory computer-readable medium having stored thereon a computer-aided design (CAD) program that when executed by the one or more processors is configured to:
generate a virtual reference frame;
receive the tracked state of the digitization device from the navigation system;
render, within the virtual reference frame, a virtual representation of the pointer tip of the digitization device having a pose of the pointer tip derived from the tracked state of the digitization device;
in response to actuation of the one or more control inputs of the digitization device, register one or more local virtual references within the virtual reference frame at a location relative to the pose of the virtual representation of the pointer tip; and
in response to actuation of the one or more control inputs of the digitization device, enable arrangement of one or more geometrical design objects within the virtual reference frame relative to the one or more registered local virtual references to facilitate surgical planning.
