Circle/L,Tanto,C,R
Circle Tangent to Line and Circle with Radius
Creates a circle of specified radius tangent to a line and tangent to a circle. IN/OUT and XL/XS/YL/YS selectors specify the solution.
What It Does
The Circle/L,Tanto,C,R operator creates a circle of specified radius that is tangent to a line and tangent to an existing circle. The IN/OUT selector specifies internal or external tangency to the circle. The Dir selector picks which solution to use.

| Selector | Options | Meaning |
|---|---|---|
IN/OUT | OUT / IN | External or internal tangency to the reference circle |
Dir | XL XS YL YS | Picks which solution based on centre coordinate |
Worked Examples
L: 0 C: 0 R: 5 IN/OUT: OUT Dir: XL
→ Circle of R=5 tangent to L0 and externally tangent to C0

Analytic Rule
Find circle of radius R tangent to L and tangent to C.
IN/OUT picks external or internal tangency to C.
Dir picks solution position.
Result: Exact analytic circle.
FAQ
What does IN/OUT control?
OUT means the new circle is externally tangent to the reference circle — it sits outside it. IN means the new circle is internally tangent — it encloses the reference circle.
