ACAD WEEK 6 Today’s lesson was about using three different kind of tools fot AutoCAD: Mirror Tool, Array Tool and Fillet Tool. Mirror Tool “MI”: The mirror tool, different from the copy tool, is used to reflect an object. For example in here we have half an object: We will select only the parts that we will like to reflect: Then we will press “MI” for the mirror option, we will press enter, and it will display the option to select the first point, which you will choose the top part of your figure, and the the end point, which will be the middle of the line underneath the figure:

Array Tool “AR”: The array tool is used to repeat an object as many times as we want, and there are two different types of array: Rectangular and polar. Rectangular: Once you have your ibject done, enter the command for Array “AR”, then select your object and choose rectangle. You will see that you will have the option to decide how many lines and columns you want.

Polar: We can use the orbit array tool, when we want to multiply our objects in a circle path, like when we are trying to make an optical illusion. First you need the object you want to array, in this case will be a rectangle. Second, you need the path, which we will use a circle. Select the array tool with the keybord command “AR” then select the object you want to array. Now select the Polar option then select the center point from where we are going to array, in this case the center of the circle. Once you’ve selected it, this shape will appear:

Now you will have the option to choose how many ítems you want, in this case I chose 50. Fillet Tool “F”: This tool is used to give rounded shape to corners or edges of an objects. In this case we are going to use a rectangle.

Once you have your rectangle, enter the command for fillet using on the keyboard the letter “F”. Once you have entered the command, you are going to write “radius” to enter how big you want the curve, I will use 3.5. Once you’ve entered it, now select the top line, and the one on the right hand side, and you will see how the curve is made. Do the same with the oposite corner.
