Circle

Ribbon : Draw | Draw 2D | Circle/Ellipse | Center & Point

Default Menu : Draw | Circle | Center & Point

Palette : Sketch | Circle/Ellipse | Circle Center & Point

All 2D circle tools provide options to generate these objects according to specific criteria such as radius, diameter, tangential connections etc. For example, a circle can either be drawn from a center to a radial point, from 2 points on the diameter or by connecting 2 tangential points to other circles or lines.The geometrical and spatial information, as well as the properties (layer, color, line style etc) for any drawn object can be found using the Selection Info Palette. For example, the radius of a circle can be changed by selecting the circle and viewing the information in the Selection Info Palette.Similarly, geometric information, for example, changing the radius or a circle be done using the Metrics pane of the Selection Info Palette.

Circles with a diameter of 20 will now be inserted onto the newly created inner intersections. To ensure accurate placement of the circles, the Intersection snap modewill be activated.

To do this, right click onto the Snap tab at the base of the screen and make sure the Intersection snap mode is activated, shown below.

Activating the Intersection snap

Close the Drawing Aids dialog box, then make sure the Snap mode facility is activated, shown below.

Select the Circle Center and Point tool from the menu options above and position the cursor over the first intersection. When the Intersection magnetic marker is display, shown below, left click to define the center of the circle.

Use the keyboard TAB key to access the data fields of the Inspector bar, then use the TAB key again to move to the Diameter field. Input a value of 20 and press ENTER. The result is shown below.

Immediately position the cursor over the second intersection and use the keyboard TAB key twice to access the Diameter field. Left click when the Intersection magnetic marker appears.

The result is shown below.
