Center Point Circle

Draw | Circle | Center Point Circle

This circle tool draws a single circle by defining the center point and diameter.

The diameter can either be defined by selecting a point in the graphics editor, or by inputting a value into the Diameter field.

The diameter of the circle can be changed after insertion by changing the value in the Diameter edit field.

Select the Center Point Circle tool from the toolbar or use Draw > Circle > Center Point Circle.

Position the cursor at the center of the radius at the top left of the sketch, shown below.
