➢ Select the fillet tool from the modify drop down menu or toolbar ❖ Fillet: filleting inside corners allows for the reduction of possible stress ❖ Extend: same process as trim, but you select the wall to extend to instead of a cutting ➢ Click on the portion of the line that you want to cut ➢ Select the shapes used as a cutting edge (you can select multiple or unnecessary shapes if it makes your selection process easier) ❖ Trim: used to cut off a portion of a shape ♦ vector: Relative polar coordinates: if you know the starting position, distance and angle of the line, enter the starting position using the above methods makes it larger, <1 makes it smaller) ♦ Start position: enter the points absolute coordinates as above or click ❖ Relative rectangular coordinates: to input a line in vector format, input the start point of the line using any of the above forms and type Ydisplacement ♦ Radius: type r and hit enter (to specify that you will be inputting the radius) ➢ Ex: circle with center at x=2,y=4 with a radius of 10 ❖ Absolute coordinates: can be input dynamically as shown above, or by clicking in the command line, at the bottom of the screen, and then typing the x-coordinate, y- coordinate (don’t forget the comma in between) ➢ Disengage dynamic entering by toggling the DYN button in the tray at the very bottom of the screen Type in the required number values and press tab to toggle between the values. ❖ Dynamic: When you start drawing a figure, a box with the required input values appears by the mouse. ➢ This method works particularly well when there are preexisting boundary points o snap to, or when using a defined grid (see Snapping below) ❖ Clicking: You can click anywhere on the screen to enter any of the above values in the order shown by the command line at the bottom of the screen. Users should try all methods to determine which one they find more comfortable. Lengths, angles, radii, start points and endpoints can all be entered using three methods. Students should erase any *.BAK files in their folders to save space. Turn off BAK save function by using setting in Tools/Options. bac : File automatically created when DWG file is saved.dxf : Drawing format needed to convert a CAD document.

dmc : File created by the Lasercam software that is imported, via memory stick, into the Lasercam computer.dwg : Drawing file automatically created by the AutoCAD software.If the lines or curves look blocky, not smooth go to View→Regen.If there is any command that you are new to, just follow the instructions on the dynamic input or in the command line at the bottom of the screen.If there is any button that you do not know its purpose, hover your mouse over the button to see a description.Customize the AutoCAD screen by picking Tools/Options/Display.Pressing Escape will exit any AutoCAD command.CAD is also used throughout industry to design machinery and architecture, as a tool for an engineer to communicate his/her ideas to those who will build the final product. In MAE 3 this program will be used to draw clock and robot parts that will be cut by the Lasercam. AutoCAD is a two dimensional drafting software.
