Shubham,

include/rt/geom.h
Other primitives define their flags there too.

The parameters which are needed to fill the rt_anno_internal(?)
structure. The sketch should be a good template for how it should
look like for the annotation.

Again: Similar as for the sketch. It can be created with an "in" too.
The annotation has a parameter "anchor point in 3D space" plus a list
of 2D segments. It should be possible to use a large portion of the
sketch code which interprets the TCL input for the annotation.
You should aim for getting a line on the screen. When you are able to
see what you are doing it will make the live easier.

Daniel
