Ctrl-RMB

Interactively places new vertices with Ctrl-RMB at the mouse cursor position.

在不选中其他顶点的情况下,使用 Ctrl-RMB 添加最基础网格元素,顶点。由于摄像头空间(电脑屏幕)是二维的,Blender无法根据确定鼠标单击产生的顶点坐标,所以新添加的顶点是放置在3D游标所确定的平面上的。

To create interconnected vertices, you can add a vertex and continuously make subsequent Ctrl-RMB operations with the last vertex selected. This will link the last selected vertex with the vertex created at the mouse position with an edge (see Fig. 逐个添加顶点。), and will continuously create and connect new vertices if you continue repeating this operation.

从一条边创建的四边形,初始边经过了自动旋转。

如果选中了一条边的两个顶点, Ctrl-RMB 单击创建一个平坦的表面,也叫做四边形。Blender会按照鼠标指针位置,从视图的观察平面创建四边形。

For Ctrl-LMB, Blender will automatically rotate the last selected Edge (the source) for the subsequent operations if you have at least one face created, dividing the angles created between the newly created edge and the last two edges, creating a smooth angle between them. Blender will calculate this angle using the last positive and negative position of the last X and Y coordinates and the last connected unselected edge. If this angle exceeds a negative limit (following a quadrant rule) between the recently created edge and the last two, Blender will wrap the faces. But if you do not want Blender to rotate and smooth edges automatically when extruding from Ctrl-RMB, you can also inhibit Blender from rotating sources using the shortcut Shift-Ctrl-RMB. In this case, Blender will not rotate the source dividing the angle between those edges when creating a face.

在这两种情况下,Blender都会告知用户在创建过程中是否进行了旋转。如果看看 调整上一步操作 面板,并按下 Ctrl-RMB 后,可以发现旋转源选项已经自动勾选;如果用的是 Ctrl-Shift-RMB,则会自动取消勾选。

If you have three or more vertices selected, and Ctrl-RMB click, you will also create planar faces, but along the vertices selected, following the direction of the cursor. This operation is similar to an extrude operation.

Tip

When adding objects with Ctrl-RMB, the extrusions of the selected elements, being vertices, edges and faces with the Ctrl-RMB, are viewport dependent. This means, once you change your viewport, for example, from top to left, bottom or right, the extrusion direction will also follow your viewport and align the extrusions with your planar view.
