1. Equations in SOLIDWORKS are the same as equations in mathematics. In this, we get to define variables and introduce dimensions that are related to those values. SOLIDWORKS list all of the variables and equations in the equations manager, which we can access to easily modify our variables and equations. Equations functions allow us to build a more connected 3D model that is easy to modify.
2. Configurations for a specific part are variations of the model that part.
3. Design tables are tables that highlight values and statuses of features. They enable us to create multiple configurations for a part by stating the variations on a design table, allowing us to create multiple new configurations at once.

• To create this model, we can start by defining our Global Variables (Y and X) at the equations manager with the values 2.5 and 0.5 respectively. Then, model the part as normal by inputting the equations instead of numerical values. Make sure to start each equation with the = sign and have the variable around quotation marks. So, to enter the equation, 2*X+0.5, as a dimension, we can enter [=2*”X”+0.5]. To double-check your model, assign the AISI 304 material to the model and your mass should be 6.65 lbs. Note that the measurement system for this part is IPS.
• We can use a manual configuration application to create this simple model. First, we can create the default configuration as normal. After that, we can add the new configurations one by one from the ConfigurationManager. For configuration C, select the This Configuration option when modifying the thickness from 10 to 5 mm. 
• We will use a design table to complete this exercise. We can start creating configuration A as the default configuration (you can rename the configuration from Default to A on the ConfigurationManager). To make the exercise easier, we can give names to the dimensions' width, length, and thickness as we are inputting the dimensions. Start a new auto-create design table and input the values shown on the table at the bottom of the drawing. Remember to double-check all of the configurations to ensure they are correct.
• This exercise uses many elementary modeling techniques in addition to design tables and equations. To complete this exercise, first, make sure to set your measurement system to MMGS. Then, start by setting up the global variable and creating the default configuration. This is by applying the equations shown in the drawing as well. After creating the default configuration, you can assign the material to AISI 1020 Steel and check the mass is 3734.82 grams. If that is the case, then you have most likely got the initial model correct.

We can start a new design table and input the table shown in the drawing. Note that we can also include equations and variables in the design table. However, when calling a variable, we have to quote the name with quotation marks. To double-check whether your configurations were set correctly, compare them with the masses given in the table listed in the second sheet of the drawing.
