Show_Circular_Arc

Functions

void Show_Circular_Arc (HC_KEY key, HC_POINT *point1, HC_POINT *point2, HC_POINT *point3)
 
void DShow_Circular_Arc (HC_KEY key, HC_DPOINT *point1, HC_DPOINT *point2, HC_DPOINT *point3)
 

Detailed Description

Function Documentation

void Show_Circular_Arc ( HC_KEY  key,
HC_POINT point1,
HC_POINT point2,
HC_POINT point3 
)

Returns the three points used to define the circular arc, as referenced by a key.

Parameters
key- Unique numeric identifier pointing to a circular arc in the database.
point1- An x-y-z triplet for the coordinates of one of three on the circumference of the circle. (A simple array of three elements can also be used in most languages.) Returned to user. Passed by reference always.
point2- As above.
point3- As above.

DETAILS

This routine finds the three points used to define the arc that corresponds to the given key. You could use this ability, for example, to extract data needed to construct a line tangent to an existing arc. The key for the arc might come from Show_Selection_Element() or Find_Contents() , or it might have been saved by your program when the arc was created (via Insert_Circular_Arc() ).

void DShow_Circular_Arc ( HC_KEY  key,
HC_DPOINT *  point1,
HC_DPOINT *  point2,
HC_DPOINT *  point3 
)

Similar to Show_Circular_Arc(), but returns double-precision values.

Parameters
key- Unique numeric identifier pointing to a circular arc in the database.
point1- An x-y-z triplet for the coordinates of one of three on the circumference of the circle. (A simple array of three elements can also be used in most languages.) Returned to user. Passed by reference always.
point2- As above.
point3- As above.
