proposed rules set:

Analyze Structure

Sense Difficulty: Moderate, modified by proximity

(possible pre-req: Magnify Senses... shift senses?)

This discipline may be kept up

Effect: Analyze Structure allows a Jedi to perceive the chemical and physical composition of an object. The Jedi can sense flaws in materials, but would need a knowledge of the appropriate technical field to evaluate gross physical construction from the information this sense gathers.
