Returns the length of a curve object.
Rhino.CurveLength (strObject [, intIndex [, arrSubDomain]])
|
strObject |
Required. String. The object's identifier. |
|
intIndex |
Optional. Number. If strObject identifies a polycurve object, then intIndex identifies the curve segment of the polycurve to query. |
|
arrSubDomain |
Optional. Array. An array of two numbers identifying the sub-domain of the curve on which the calculation will be performed. The two parameters (sub-domain) must be non-decreasing. If omitted, the length of the entire curve is returned. |
|
Number |
The length of the curve if successful. |
|
Null |
If not successful, or on error. |
