**Introduction to Sketching**

Learn about sketching basics including the sketch plane, legend, constraints, context menu options, and construction geometry.**Variables**

Create and assign variables to parameters when modeling.**New Sketch**

Start a new sketch and select a sketch plane.**Project**

Project selected geometry onto the sketch plane as construction geometry.**Intersect**

Extract curves resulting from the intersection of the sketch plane with selected parts.**Point/Lines**

Sketch and edit a point, line, polyline, or line-arc.**Rectangles**

Sketch and edit a rectangle.**Polygons**

Sketch and edit a parallelogram or a regular polygon.**Circles**

Sketch and edit a circle.**Ellipses**

Sketch and edit an ellipse or an elliptical arc.**Arcs**

Sketch and edit an arc.**Splines**

Sketch and edit a spline.**Dimension**

Use the Dimension tool to define and/or constrain the dimensions of a sketch.**Trim/Break**

Trim or split a sketch curve.**Extend**

Extend or shorten an entity of a sketch curve.**Fillet**

Round the corners of 2D sketch curves to create fillets with the same radius or different radii.**Offset/Mirror**

Offset or mirror a sketch curve.
