Overview of Functions
CIM's rebar generation process provides an environment for modeling longitudinal profiles, transverse rebars, and stirrups in arbitrary planes and then arraying them in any direction.
At this time, the rebar drawing process in the rebar plane is efficient in the 2D working environment, so a separate rebar draw mode is provided.
Therefore, this function explains the mode and the rebar draw function that is switched after selecting the plane to construct the rebar in the rebar draw function.
