 ==== Geometric Dimension and Tolerance (GDT) ==== ==== Geometric Dimension and Tolerance (GDT) ====
 +  * Objectives of GD&T
 +    * GD&T communicates a more precise part design, which can increase tolerances and reduce manufacturing costs by avoiding scrapped parts and saving time
 +    * GD&T is shown on a print - a document containing all the instructions necessary to manufacture a part. A print, or blueprint, includes a part drawing, dimensions, and notes.
 +    * Print includes the part's shape, dimensions and tolerances (allowable differences between a finished part and its intended design)
 +    * A datum represents a feature and establishes a reference for measuring and inspecting a part

 +  * Compartment 1

 +  * Compartment 2

 +==== Material Condition Modifiers ====
 +  * Maximum Material Condition (MMC)
 +    * defines the most amount of material allowed for a feature to fit and function properly
 +    * for internal features such as a hole, MMC represents the smallest hole allowable
 +  * Least Material Condition (LMC)
 +    * defines the least amount of material allowable for a feature to function without too much looseness or slack
 +    * for internal features such as a hole, LMC represents the largest hole allowable
 +  * Bonus tolerance may be permissible if a feature deviates from MMC or LMC. Regardless of feature size (RFS) indicates that the tolerance applies regardless of its material condition and rules out the possibility of bonus tolerance.

 +  * [Q] How do I make a part (.ipt) shinny?
 +    * In order to see the reflections and "​shininess"​ of the materials, I had to set my lighting style to either "Two Lights"​ or "One Light"​. Some of the lighting environments show the reflections,​ and others don't. The default Inventor 2020 one is 'Light Theme IBL' which for whatever reason doesn'​t have the reflections.
