Circle (parts)

The 'Circle (parts)' command is used to draw complete circles or parts of circles:

With all four commands, the required coordinates of the input points can be entered using the keyboard, or by positioning the cursor on the screen. If you are using the cursor, when the cursor is in the correct location, press the left mouse button (or <Enter> key) to fix the position. Additionally, when the cursor is used to enter the second point, the resultant circle or arc, etc., will be displayed in dynamic mode until the second point is fixed.

When drawing a circle, you are first prompted to enter the point representing the center of the circle and then another for the radius.

With half and quarter circles you are first prompted to enter the point representing the center of the circle and then another for the radius. In addition to determining the radius, the second point also determines the direction of the circle segment. Half and quarter circles are drawn along the 'X' or 'Y' axis of the center point.

For an arc, you are prompted to enter the point representing the center, and then start and end points of the arc. The start point determines the radius, and the end point determines the arc length.

Circle segments will not be recognised by the list generator or other automatic functions. You can set line width and colours.

When a circle, or segment, is drawn with a line width greater than 0,25mm, then the thickness is generated towards the inside of the circle and not symmetrical about line. If you need to select a circle having thick lines, e.g. for a modify operation, it must be selected  by placing the cursor on the outer edge of the circle.

Hint

Arcs are always drawn counter-clockwise. By selecting the appropriate start and end points you can draw any segment
