Curves

• Angle Arc — An arc made by turning a start point around an axis by an angle.
• Arc — A circular arc that starts at Point 1, passes through Point 2 and ends at Point 3.
• Blend Curve — A connecting curve that joins two curves at a chosen distance along each.
• Conic Through Points — A conic arc from a start point to an end point, bent toward an apex point where its two end tangents meet.
• Control-Point Spline — A smooth B-spline curve shaped by a list of control points.
• Curve Frame — A coordinate frame sitting on a curve at a given distance from its start.
• Curve Intersections — Finds every place a curve passes through a Solid's surface and returns those points as a Point List, in order along the curve.
• Curve Point — The point on a curve at a given distance from its start, measured along the curve.
• Divide Curve — Places points along a curve at equal spacing measured along the curve, starting at its first point.
• Interpolated Spline — A smooth curve that passes exactly through every listed point, in order.
• Intersection Curve — The curve where the surfaces of two Solids meet, traced numerically.
• Join Curves — Chains curves that meet end to end into one continuous Curve.
• Line — A straight line segment between two points.
• Line Along Direction — A straight line segment that starts at a point and runs a given length in a given direction.
• Mirror Curve — The mirror image of a curve across a plane.
• Polyline — An open Curve made of straight segments joining the listed points in order.
• Project Curve to Plane — Flattens a curve onto a plane by moving each of its points along the plane's normal.
• Tangent Arc — A circular arc that leaves a start point in a chosen direction and ends at an end point.
• Tangent Conic — A conic arc from a start point to an end point that leaves and arrives along given directions.
• Tangent Spline — A smooth cubic curve that passes through every point and leaves each one along its own tangent vector.
• Trim Curve — Cuts a curve where it crosses a Solid's surface and keeps the pieces outside the Solid (or inside, with Invert).
