GetCurve Properties |
The GetCurve type exposes the following members.
Properties| Name | Description | |
|---|---|---|
 | Degree |
Degree of the resulting curve. Default is 3.
Setting any value other than 3 clears SubDFriendly.
|
| EndTangent |
End tangent of an interpolated curve. Only used when UseEndTangent is true.
|
| FirstPointPrompt | Prompt used when getting the first point. The default is the localized "Start of curve". |
| KnotSpacing |
Knot spacing used when interpolating. Default is Chord.
Only Uniform, Chord and ChordSquareRoot are accepted. Closing the curve selects the periodic
form of the value set here, so passing a periodic value would take the knot style out of range.
Ignored when SubDFriendly is true.
|
| Points |
The points picked during the most recent call to GetControlPointCurve or GetInterpolatedCurve.
Empty before the first call. When the curve was closed, the first point is repeated at the end.
|
| SecondPointPrompt | Prompt used when getting the second point. The default is the localized "Next point". |
| Sharp |
When true, closing the curve produces a sharp corner at the seam instead of a periodic curve.
Default is false.
|
| StartTangent |
Start tangent of an interpolated curve. Only used when UseStartTangent is true.
|
| SubDFriendly |
When true, the result is a cubic, uniform, non-rational curve that is either periodic or has
zero second derivatives at both ends. Default is false.
Setting this to true sets Degree to 3, because a SubD friendly curve is always cubic.
While this is true, KnotSpacing, StartTangent and EndTangent are ignored.
|
| ThirdPointPrompt | Prompt used when getting the third and following points. The default is the localized
"Next point. Press Enter when done". |
| UseActiveLayerLinetype |
When true, the linetype of the active layer is used for the dynamic drawing. Default is false.
|
| UseEndTangent |
When true, an interpolated curve ends tangent to EndTangent. Default is false.
Ignored on a closed curve unless Sharp is true, and ignored while SubDFriendly is true.
The getter offers its EndTangent option to the user only at degree 3 with SubDFriendly off;
a tangent set here still applies at any degree.
|
| UseStartTangent |
When true, an interpolated curve starts tangent to StartTangent. Default is false.
Ignored on a closed curve unless Sharp is true, and ignored while SubDFriendly is true.
The getter offers its StartTangent option to the user only at degree 3 with SubDFriendly off;
a tangent set here still applies at any degree.
