    1. Parametric Sketching

    2. Motivation Solid primitives not typically supported in parametric modelers ? must create a 2D profile, then sweep

    3. Feature Creation Procedure Choose sketch plane, either a: Default work plane Planar face of existing feature Work plane Rough sketch Some geometric constraints applied Add/delete geometric constraints Parametric dimensioning Feature creation Repeat 1 - 5

    4. Construction Geometry Geometry created as part of the parametric modeling process that does not represent actual part geometry. Includes: Work planes Work axes Work points
