Reference Video: Landing Gear Arm Design
NOTE: Video overviews Design, Assembly in Context and Layout
NOTE: Tolerance Display (tol_display) in layout: If tol_display is turned off in layout Goto the Following: File > Prepare > Detail
Options > Change > Type in tol_display > Turn the option to Yes > Add/Change > Apply > Ok
Reference Tutorial: Modify/Add Features to Individual Parts in an Assembly File
NOTE: Tutorial Shows how to Cut Angle on Base Piece that is flush with Top Arm
Layout: ALL on ONE sheet
Views Include: Sectioned Assembled Orthographic, Assembled Isometric, Individual part views, BOM Chart and any other views designer deems necessary.
Label each View (Including Assembly Views)
Part Top Arm: Include
1. Top Datum as Annotated Datum: Select Top Datum in Layout > Right Mouse Button: Properties > Annotated Display Option (Option: Looks like A in a Square Box) > Rename (0, REF. or BASE, ETC.)
2. Draw in Centerpoints for the two center arcs that are not concentric > Set Radius Dimensions > Flip Arrowheads so the dimension leader line extends to the centerpoint
Reference Tutorial: Centerline Using Sketch Tool
Used when a Feature on the Solid Model is Designed as an Arc (Geometry less than 360 Degrees)

Grid Lines: Any Drawn Grid Lines to Seperate Views/Drawings will be .03 Thick (Same as Border Lines). Use Reference Selection Tool to select an edge from the part to snap parallal to perpendiculiar to; similiar to drawing in centerlines.
Geometric Dimensioning and Tolerancing (GD&T) Basics
Geometric Dimensioning and Tolerancing (GD&T) is a symbolic language used in engineering to define the size, shape, and allowable variations of parts, ensuring they fit together correctly and function as intended. It provides a precise method for communicating design intent on blueprints and CAD models, improving manufacturing efficiency, reducing defects, and ensuring consistency across different production locations. GD&T controls variations based on a feature's function, using symbols to specify controls for form, orientation, location, profile, and runout, according to standards like ASME Y14.5 and ISO GPS
