## How do you do equations in Solidworks?

In an open sketch, do one of the following:

1. Click Equations (Tools toolbar).
2. Click Tools > Equations.
3. Right-click the Equations folder in the FeatureManager design tree, and select Manage Equations.

## How do you create a parametric dimension in Solidworks?

Parametric Dimensions

1. Open a sketch, sketch a rectangle, and dimension the rectangle.
2. Modify the dimensions as needed while creating the sketch.
3. Extrude a block base feature.
4. Complete the feature to close the sketch and show the solid in shaded mode.

## How do you write parametric equations?

Example 1:

1. Find a set of parametric equations for the equation y=x2+5 .
2. Assign any one of the variable equal to t . (say x = t ).
3. Then, the given equation can be rewritten as y=t2+5 .
4. Therefore, a set of parametric equations is x = t and y=t2+5 .

## How do I import a formula into Solidworks?

2. Select the Equation View .
3. In the Equations section, click an empty cell in the Name column.
4. Click a dimension in the graphics area. …
5. After = (equal sign), add a term to the equation by doing one of the following: …
6. Type + (plus), – (minus) or another mathematical symbol.

## How do you add parameters in Solidworks?

To access the Parameters dialog box, click Insert > Design Study > Parameters. You can also view defined parameters in the Parameters node of the Simulation study tree. Type a name of the parameter. Define global variables in the Add Equation dialog box.

## How do I make dimensions the same in Solidworks?

Double click the dimension, then in the Modify dialog box, type = (equal sign). You must enter the equal sign to assign a global variable to the dimension. If you do not enter the equal sign, you can create a new global variable, but it will not be assigned to the dimension.

1. Right-click the dimension and select Link Values.
2. In the Shared Values dialog box, select or type a Name. In addition to the linked variable names you create, global variables are also available for selection under Name. …
3. Click OK. …
4. Repeat for as many dimensions as needed.

## How do I add an equation to a dimension in Solidworks 2020?

In the model, double-click a dimension. The Modify dialog box for dimensions displays, showing the name of the dimension and the current value. In the second line of the Modify dialog box, enter = (equal sign). Then enter an equation in the same way as in the Equations dialog box.

## Why do we use parametric equations?

Parametric equations can be used to describe all types of curves that can be represented on a plane but are most often used in situations where curves on a Cartesian plane cannot be described by functions (e.g., when a curve crosses itself).
