# Sketch and Geometry Tutorials

Learn how to create 2D sketches and parametric parts, prepare and simplify solid geometry, and model surfaces.

Learn how to create 2D sketches and parametric parts, prepare and simplify solid geometry, and model surfaces.

**Video Tutorial: Getting Started with Sketching**

Learn how to define the sketch plane, create a fully defined sketch, add dimensions, and modify constraints.**Video Tutorial: Creating a Parametric Part**

Sketch a simple parametric part using variables and dimensions.**Video Tutorial: Construction History Basics**

Learn how to use construction history to edit and suppress construction features in the history timeline.**Video Tutorial: Creating a Parametric Bracket**

Generate multiple sketches to create a parametric bracket with recessed areas using the Offset, Push/Pull, and Boolean tools, and using a construction line as a reference. You will also assign dimensions and create variables.**Video Tutorial: Using Construction Geometry**

Learn how to use constraints and construction geometry to create more sophisticated sketches. In this example, you'll build a tapering arm for a clamp around a reference centerline, paramaterizing the sketch in terms of the construction lines.**Tutorial: Simplifying Geometry**

Learn how to find and remove pockets, holes, rounds, and fillets.**Tutorial: Surface Modeling**

Analyze a surface model, create surfaces using the Midsurface and Patch tools, then optimize the surfaces.
