Centre + Pt

Draw a geometry circle at a centre point and through a point on the circumference.

This function allows you to draw a geometry circle by entering the centre point and indicating a point on the circumference. The point on the circumference defines the radius of the geometry circle.

The circle's plane passes through the centre point, with the normal specified by the direction of the drawing plane when indicating the centre point. The point on the radius is projected onto the circle's plane in the direction of the plane.

Geometry lines are infinite lines that never print or plot, and are seen in all layers. To change the appearance of all geometry, see Geometry Settings under System Settings.

Procedure

To draw a geometry circle from the centre point to a point on the circumference:

Select Geometry ► Circles ► Centre + Pt or click the icon in the Geometry toolbar.
You are prompted to:

Indicate centre point of circle

You can now position the cursor and press [Enter], or click in the drawing to indicate the centre of the geometry circle.
You are prompted to:

Indicate point on radius

The circle is drawn on the screen with the cursor positioned on the circle circumference. As the cursor moves the circle will increase or decrease in radius.

Position the cursor over the desired radial point and click or press [Enter].

You can use the Coordinate jump to draw between two specified coordinates, or the Polar_Jump to move a set distance at a specified angle. Alternatively, use [Up], [Down], [Left] and [Right] arrows to draw the circle to a set radius.

You could also use the snap or jump functions to draw the geometry circle with accuracy.

The function repeats.

Right-click and select Quit to end the function. Alternatively, press [Esc].
