# Sketching

Create and edit a 2D sketch curve. A sketch curve is any "wire" entity such as a line, rectangle, circle, or arc.

Create and edit a 2D sketch curve. A sketch curve is any "wire" entity such as a line, rectangle, circle, or arc.

**New Sketch**

Start a new sketch and select a sketch plane.**Change the Sketch Plane**

Change the sketch plane of an existing sketch curve.**Sketch Constraints**

Apply geometric relationships such as tangency and perpendicularity to sketch curves.**3D Sketching**

Create a 3D sketch.**Import Entities**

Import geometry that was not created using a sketching tool by projecting it onto a sketch plane as construction geometry.**Points/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**

Apply and edit a dimensional constraint to control the size and proportions of a sketch. You can make a dimension "driven" so that it's a regular dimension, not a constraint.**Image Plane**

Create an image plane that you can use as a background reference image, so you can trace lines and curves to start your design.**Transform**

Translate or rotate sketch entities.**Trim/Divide**

Trim or divide 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.**Pattern**

Create a linear or circular pattern of sketch entities.
