Where can I find this command?
CurveThroughPolyline 可從多重直線的頂點建立曲線。
步驟
| 4 | 選取多重直線。 |
指令行選項
Degree
設定曲線或曲面的階數。
建立階數較高的曲線時，控制點的數目必需比階數大 1 或以上，得到的曲線的階數才會是設定的階數。
曲線類型
控制點
將曲線的控制點放在與選取的點物件、頂點或控制點相同的位置。
Curve control points match input.
Resulting extruded surface.
內插點
建立通過選取的點物件、頂點或控制點的曲線。
Curve matches input.
Resulting extruded surface.
節點
Determines how an interpolated curve is parameterized. When the spacing between the picked points is equal for the whole curve, all three parameterizations generate the same curve.
When you draw an interpolated curve, the points you pick are converted into knot values on the curve. The parameterization means how the intervals between knots are chosen.
一致
The knot spacing is always 1 and is not based on the physical spacing of the points. Uniform parameterization can be used if the point spacing is roughly equal and it is desirable to draw several curves that have the same parameterization. This is possible only with uniform curves (unless you rebuild the curves). Uniform guarantees that every control point affects the surface exactly the same way, no matter how much the surface is edited.
弦長
以內插點之間的距離做為節點的參數間距，當曲線插入點的距離差異非常大時，以弦長參數化建立的曲線會比一致的參數化好。
弦長平方根
以內插點之間的距離的平方根做為節點的參數間距。
