VariableBlendSrf 指令旨在在两个曲面之间建立不等距的混接曲面，修剪原来的曲面，并将曲面组合在一起。
步骤
- 点选两个要建立不等距混接的曲面的边缘附近。
曲面必需有交集。
曲面的交线上会出现控制杆。 - 按 Enter 键使用默认半径。
或
指令显示半径选项时输入新的半径。 - 设定命令行选项
或
选取要编辑的控制杆

Tips for using handle grips
- The default handles have one grip that can be dragged to change the radius.
- Any added or copied handles have two grips.
- Use the grip on the edge to move the handle along the edge.
- Use the grip in the center to change the radius at the handle location.
The Radius and Distance options appear on the command line when you drag a handle grip.
| Radius/Distance options | |
|---|---|
FromCurve | Select a curve. The radius of the curve at the picked location will be used. |
FromTwoPoints | Pick two points to show the radius distance. |
| Handle options | |
AddHandle | Adds a handle along the edges. |
CopyHandle | Adds a new handle using the distance from the selected handle. |
RemoveHandle | Visible only when at least one handle has been added. |
SetAll | Sets the distance or radius for all handles. |
LinkHandles | Editing a single handle updates all handles. |
Note
Only added handles can be removed.
The default handles at the ends of each open edge segment cannot be moved or deleted. This is the minimum information the command needs in order to work.
The handle at the end of a single closed edge can be moved but not deleted.
If a radius is set larger than the edge radius at the handle location, the handle changes to dark red and displays the edge radius. It is the maximum radius allowed at the handle location. In the case below, a radius larger than 3.102 units will fail.
| 路径型式选项 | |
|---|---|
与边缘距离 | 以到边缘的距离画出曲面的修剪路径。 |
滚球 | 以滚球的半径画出曲面的修剪路径。 |
路径间距 | 以两个曲面的修剪路径之间的距离画出曲面的修剪路径。 |
修剪并组合 | 以结果曲面修剪原来的曲面并组合在一起。 只有当“修剪并组合”=“否”的时候建构历史才有效。 |
预览 | 显示动态预览，当您更改选项时预览结果也会出现相应的变化。 |
技巧
- 保持最大半径和最小半径都不要超出模型。
- 使用 MergeAllCoplanarFaces 指令或其他建模方法尽可能的减少边缘数量，混接曲面修剪与组合相邻的曲面时，相交边缘越少，出错越少。
- 确保有足够的空间可以让混接曲面剪切以及组合相邻的曲面，混接能否成功取决于曲面之间的角度关系、转角路径处弯曲的尖锐程度以及路径类型。
