Options

The following options are available to create arcs.

:CEN_RAD_ANG - specifies a center and radius or peripheral position, and then begin and end points or angles for the arc.
:CENTER - specifies a center point and a radius either directly, or using a peripheral point at the desired distance from the center of the arc. You must define a new center point for each arc you create.
:3_POS - specifies three peripheral points through which the arc must pass.
:DIAMETER - specifies two peripheral points which must lie on the diameter of the arc.
:CONCENTRIC - specifies a circular element to be concentric to, and the positive or negative offset. A positive offset will create an arc larger than the original, while a negative offset will create a smaller one.
The automatic loop facility lets you create several concentric circles in one operation.
:SMOOTH - specifies the element to be smooth to, which end of the element will be extended, and the end position.
The automatic loop facility lets you create a series of smooth connected arcs.
:CLOCKWISE - reverses the default direction of arc definition.

When to use

Use this action to create a counter-clockwise arc anywhere on the active workplane.

Example

Enter ARC and specify the location and size of the curve as follows:

ARC :DIAMETER 50,50 100,100
