HC_KEY Insert_Circular_Arc | ( | const HC_POINT * | point1, | |
const HC_POINT * | point2, | |||
const HC_POINT * | point3 | |||
) |
Generates a portion of the circumference of a circle.
point1 | - An x-y-z triplet for the coordinates of one of three ordered on the circumference of the circle. A simple array of three elements may also be used for each parameter. Passed by reference always. | |
point2 | - As above. | |
point3 | - As above. |
Circular arcs are grouped with lines, polylines, and elliptical arcs for rendering purposes. The rendition of an arc can be altered through the use of line color, line weight, and line pattern. An arc's visibility and selectability can be controlled by the "line" or "polyline" keywords.
Make sure the points are not colinear. The system issues an error message if all three points lie on a line, or if two points are coincident.
Zooming in close on very large circular arcs results in a linear appearance.

Similar to Insert_Circular_Arc(), but accepts parameters of type double for increased precision.
point1 | - An x-y-z triplet for the coordinates of one of three ordered points on the circumference of the circle. A simple array of three double-precision elements may also be used for each parameter. Passed by reference always. | |
point2 | - As above. | |
point3 | - As above. |
