Edge Operations
Use following methods of the cadlib object to create and manipulate edges.
A few methods also appear on the Path object, but difference is, methods on the Path object return current instance of Path, used for chaining.
Use methods below when you don’t want to build a set of edges incrementally.
edge
Creates a new edge.
Syntax
cadlib.edge()
Parameters
Takes no parameters
Returns
arc2p
Creates an edge representing an arc passing thru two points.
Syntax
cadlib.arc2p(center, axis, radius, p1,p2)
Parameters
| Name | Type | Description |
|---|---|---|
| center | ||
| axis | ||
| radius | ||
| p1 | ||
| p2 |
Returns
arcEllipse
Creates an edge representing an ellipitcal arc.
Syntax
cadlib.ellipse(center, axis, majorRadius, minorRadius, p1,p2)
Parameters
| Name | Type | Description |
|---|---|---|
| center | ||
| axis | ||
| majorRadius | ||

| p1 | ||
| p2 |
Returns
_bezierCurve

Syntax
cadlib.bezierCurve(poles, weights)
Parameters

Returns
bsplineCurve
Creates an edge from the spline curve.
Syntax
