Click the Circle command button on the ribbon to activate the Circle command in the Center-Radius mode. If there is no Sketch Plane on page 138 currently active, you are prompted to select one.
Click the Circle command button on the ribbon to activate the Circle command in the Center-Radius mode. If there is no Sketch Plane on page 138 currently active, you are prompted to select one. You can also define a Circle in other ways by picking any one of the drop-down options on the command button.
■ Center-Radius Circle: Define a circle by clicking once to pick a center point, and then clicking again to define the radius.
■ 2-Point Circle: Define a circle by picking the endpoints of its diameter
■ 3-Point Circle: Define a circle by picking three unique points on its circumference.
■ 2-Tangent Circle: Define a circle by picking two tangent lines and then a point to place its center.
■ 3-Tangent Circle: Define a circle by picking three tangent lines.
You can also switch between the different Circle creation options from the drop-down menu that is available when you are not in the middle of a creation operation. Press the down arrow key to get this option.
If there are existing sketch geometries on your Sketch Plane, you receive feedback on points that lie on other sketch entities, midpoints, and Grid snap points. See Sketch Inferencing on page 162 to learn more.
Although you cannot define explicit constraints while creating Sketch entities, some constrains are implicitly detected when creating/editing Sketch entities.
See Sketch Constraints on page 169 to learn more. If you are creating a Circle such that it is tangent to another Line or Circle, you see a red tangent symbol (a circle with a line on top) when the constraint is inferred.
To exit the Circle command, press the Esc key or pick any other command. Any Circle that is currently in a preview state is discarded.
