## How do I change the size of a circle in SolidWorks?

**Creating Circular Dimensions**

- Click Smart Dimension. (Dimensions/Relations toolbar) or click Tools > Dimensions > Smart.
- Select the circle.
- Drag the dimension and click to place it.
- Set the value in the Modify box and click .

## How do you change the radius of a circle on shape?

Click on the point location where you want the center of the circle to be located, and then click on another location to **set the radius** for the circle. You can also click and drag outward from the center of the circle and let go to set the radius.

## How do you find the radius in Solidworks 2019?

Measures distance, angle, and radius in sketches, 3D models, assemblies, or drawings. Also measures the size of and between lines, points, surfaces, and planes. To open the Measure dialog box: **Click Measure (Tools toolbar) or Tools > Evaluate > Measure**.

## How do you dimension a Smart Circle?

**Creating Circular Dimensions**

- Click Smart Dimension. (Dimensions/Relations toolbar) or click Tools > Dimensions > Smart.
- Select the circle.
- Drag the dimension and click to place it.
- Set the value in the Modify box and click .

## Does a circle have dimensions?

A circle is a **one-dimensional object**, although one can embed it into a two-dimensional object. More precisely, it is a one-dimensional manifold.

## How do you align two circles in Solidworks?

**To align sketches:**

- Select a line or a point in a sketch to be aligned with another sketch.
- Hold Ctrl and select a line or a point in the second sketch to which the first sketch is to be aligned.
- Click Align Sketch (2D to 3D toolbar), or click Tools > Sketch Tools > Align > Sketch.

## How do you edit a line on shape?

In the Drawing properties flyout, click **the “Views” tab** and you will see options for “thickness.” You can adjust the line thickness of visible edges, tangent edges, hidden edges, and hatches independently.

## Is a radius half the diameter?

The radius of a circle is the length of the line segment from the center of a circle to a point on the circumference of the circle and diameter is a line segment from one end of the circle to the other end of the circle passing through the center of the circle. So, the radius is **half the length of the diameter**.

## How do you change from radius to diameter in Creo?

Click Modeling and then, in the Modify 2D group, **click Radius**. The Change Rad/Dia dialog box opens. When you change from the radius mode to the diameter mode , the following circle commands change: On the Modeling tab, in the Modify 2D group, Radius changes to Diameter.

## What is the dimensional formula of radius?

For example, if r is the radius of a cylinder and h is its height, then we write **[r] = L and [h] = L** to indicate the dimensions of the radius and height are both those of length, or L. Similarly, if we use the symbol A for the surface area of a cylinder and V for its volume, then [A] = L^{2} and [V] = L^{3}.
