Cow Catcher

Make sure you create a sketch on the XZ PLANE

Cow Catcher

Dimensions for one side

Cow Catcher

Create 2D Sketch, then hold and drag up, then type 0.75

Cow Catcher

Cow Catcher

Use Project Geometry

Dimensions for other side

Cow Catcher

• Loft

• Shell (0.1)

• Create 2D Sketch (then use offset tool), dimension .1 from top, then extrude CUT 0.05

• Make pegs on back

Cow Catcher

Make sure you have the correct dimensions, then extrude .125 and chamfer

Axle Peg

Make sure you create a sketch on the XZ PLANE

Axle Peg

• Sketch half of cylindrical profile and revolve.

• 0.25/2, then 1, then unknown distance, then .031, create arc, then close shape

• Add dimensions

• .422/2, then arc=.236,

Axle Peg
