Circle/Centre,P,Tanto,C
Circle at Centre Point Tangent to Circle
Creates a circle with a specified centre point that is tangent to an existing circle. The radius is computed automatically from the distance between the centre and the tangent circle.
What It Does
The Circle/Centre,P,Tanto,C operator creates a circle whose centre is at a specified point and whose radius is determined by tangency to an existing circle. No radius input is needed — the radius is computed automatically.
Syntax
Circle/Centre, P, Tanto, C
Quick Input
P: 0
C: 0
Direction Selector
No direction selector required. The centre point P fully determines the circle. The radius is computed as the distance from P to the nearest point on circle C (external tangency).
Worked Examples
P: 0 C: 0
→ New circle centred at P0, tangent to C0
Radius = distance from P0 to C0 circumference
Analytic Rule
Centre at P.
Radius = |dist(P, centre_of_C) - radius_of_C| for external tangency.
Result: Exact analytic circle.
FAQ
Is the radius computed automatically?
Yes. You only specify the centre point and the reference circle. XyzPilot computes the radius from the geometry.
