Circle

You can draw a circle in one of the following eight ways using the following functions of the "circle" submenu:

• Center & point - draws a 2-point circle (center and any point on the circle) in "rubber band circle" mode;

• Center & radius - draws a circle by the center point and specified radius;

• 2 pts on diameter - draws a circle by the two endpoints on any of its diameters;

• 3 point circle - draws a circle, specified by any 3 points on it;

• Tangent to line - draws a circle tangent to a selected line;

• Tangent to two lines - draws a circle tangent to two selected lines;

• Tangent to circle - draws a circle tangent to a selected circle;

• Tangent to line & circle - draws a circle tangent to a selected line and to a selected circle;

Circle by a center and a point

The "center & point" function draws a 2-point circle (center and any point on the circle) in "rubber band circle" mode.

PROMPTS:
• Circle center?
• Point on circle?
If both points coincide you get the following error message:
"Identical points"

PARAMETERS available via the "params" function of the control menu:
"linetype, color, level of detail".

Circle by a center and a radius

The "center & radius" function draws a circle by the center point and specified radius.

PROMPTS:
• Circle center?
• Circle radius?
The radius may be entered as a numeric value or specified as the distance between two points. If both points coincide you get the following error message:
"Identical points"

PARAMETERS available via the "params" function of the control menu:
"linetype, color, level of detail"

Circle by two points on the diameter

The "2pts on diameter" function draws a circle by the two end points on any of its diameters.

PROMPTS:
• First circle point?
• Second circle point?
If both points coincide you get the following error message:
"Identical points"

PARAMETERS available via the "params" function of the control menu:
"linetype, color, level of detail"

Circle by three points

The "3 point circle" function draws a circle, specified by any 3 points on it.

PROMPTS:
• First circle point?
• Second circle point?
• Third circle point?
If the points are specified on a line you get the following error message:
"The three points are co-linear"

PARAMETERS available via the "params" function of the control menu:
"linetype, color, level of detail"

Circle tangent to a line

The "tangent to line" function draws a circle tangent to a selected line. You must specify the circle radius, two points on the direction on which the center of the circle lies and the point indicating the side of the circle respecting the line.

PROMPTS:
• Select object
• Circle/arc radius?
• First point of the direction?
• Second point of the direction?
• At which side?
PARAMETERS available via the "params" function of the control menu:
"linetype, color, level of detail"

Circle tangent to two lines

The "tangent to two lines" function draws a circle tangent to two selected lines. You must specify the circle radius.

PROMPTS:
• Select object
• Select object
• Circle/arc radius?
PARAMETERS available via the "params" function of the control menu:
"linetype, color, level of detail"

Circle tangent to a circle

The "tangent to circle" function draws a circle tangent to a selected circle. You must specify the circle radius, two points on the direction on which the center of the circle lies and the point indicating the side of the circle respecting the line.

PROMPTS:
• Select object
• Circle/arc radius?
• First point of the direction?
• Second point of the direction?
• At which side?
PARAMETERS available via the "params" function of the control menu:
"linetype, color, level of detail"

Circle tangent to a line and a circle

The "tangent to line & circle" function draws a circle tangent to a selected line and to a selected circle. You must specify the circle radius.

PROMPTS:
• Select object
• Select object
• Circle/arc radius?
PARAMETERS available via the "params" function of the control menu:
"linetype, color, level of detail"
