Change Radius and Angle Subtended

RADIUS value [Design]

Sets RADI. For TCOD CENT this moves the ‘from’ and ‘to’ points radially (by the change in the value of the radius). Centre point position and ASUB are not altered. For TCOD ENDP this moves the ‘through’ point and changes ASUB; the positions of ‘from’ and ‘to’ points are unchanged.

RADIUS X value Y value

RADIUS E value N value U value

RADIUS IDP @

.

For TCOD ENDP this is like THPT @.

ASUBTENDED value [ANTICLOCKWISE]

ASUBTENDED value CLOCKWISE

Sets ASUB. (A positive angle is anticlockwise, a negative one clockwise.)

For TCOD ENDP this repositions the ‘through’ point (mid-way along the Arc) and changes RADI; ‘from’ and ‘to’ point positions are unaltered. For TCOD CENT this moves the ‘to’ point of the arc. Centre and ‘from’ points and radius are unchanged.

ASUBTENDED CLOCKWISE

ASUBTENDED ANTICLOCKWISE

Sets the value of ASUB to be negative or positive, respectively.

ASUBTENDED @

For TCOD ENDP this is like THPT @; For TCOD CENT this alters the angle subtended and hence moves the ‘to’ point of the Arc. The new position of the ‘to’ point lies on the line joining the centre-point and the cursor position; centre and ‘from’ points and radius are unaltered.
