<p>Press the '''Create Sketch''' button in the top left of the tool bar. Then select the plane on which you would like to create a sketch. If there are no components to select a plane from, you must select a plane from the 3D space (X plane[red], Y plane[green], Z plane[blue]). It may be helpful to choose the initial orientation that best suits your preferences and your project. For example, if the component is relatively long and flat, it may be useful to start on the Z plane. In this scenario, you will create the sketch of the bottom or top surface. </p> [[File:Sketch planes.png|120px|thumb|right|Example of Sketch Planes]]

If you'd like to create a sketch from a component that already exists, press ... Option 1: Press the '''Create Sketch ''' button and select the surface of the component you'd like to make a sketch plane from. The surface will be highlighted a light yellow color.  Option 2: Right click on the surface you would like to draw on and select '''Create Sketch.''' Sketch planes '''must be created from a 2D plane'''. In other words, the surface you choose must be flat if you do not create additional planes. To see advanced information about planes, see the appropriate Wiki page.

*'''Curve''': 2D feature (line, spline, et al.) in a Sketch. A Closed Curve is one whose start and end points are at the same spot, and a closed curve creates a profile.*'''Profile''': 2D shape (circle, polygon, et al. created by a complete closed curve or set of curves in a Sketch.*'''Feature''': Geometry from which bodies can be created. Features usually include profiles.

==Most Commonly Used Tools==

*'''Line (hot key: L)'''**Creates a line of a certain length and angle from its origin*'''Center Diameter Circle ( hot key: C)'''**creates a circle of a given diameter*'''Offset (hot key: O)'''**After selecting an object it creates an outline around it a certain distance away*'''Extrude( hot key:E)''' 2nd icon from left in Create, 3D rectangle with up arrow

*'''Hole:''' 4th icon from left in Create, 3D square with circular hole**Creates a hole in the 3D object*'''Rectangular Circular Pattern:''' 5th icon from left in Create, four mini squares attached into a square**Duplicate faces, bodies, features...*'''Press Pull:''' 1st icon from left in Modify, rectangle pulling wide with arrow**Can stretch or cut an around a center object*'''Fillet(hot key:''' 2nd icon from left in Modify, curved triangle**Added features to the edges*'''ShellF) :''' 3rd icon from left in Modify, 3D square with square hole**hollows out inside of rounds an edge at a 3D objectgiven radius

<br />==ChecklistWorkshop checklist=====Learning Objectives===By the end of this Workshop, you should: #know that CAD stands for Computer-Aided Design.#understand the 3-dimensional CAD process, from conception to export.#be able to explain what parametricity means in the context of CAD.#understand dimensions and constraints, and how they contribute to an object.#know the difference between fillets and chamfers. ===Measurable Outcomes===By the end of this Workshop, you should be able to:

#be able create a sketch with 2-dimensional features.#constrain features of a 2-dimensional sketch to create each other.#use construction linesto relate features to each other.#be able to create circlesa 3-dimensional body from a 2-dimensional sketch.#modify an existing 3-dimensional body.
