3D游标

The 3D Cursor is a point in 3D space which can be used for a number of purposes.

放置

There are a few methods to position the 3D cursor.

用鼠标直接放置

Positioning the 3D cursor with two orthogonal views.

With the cursor tool enabled, using LMB in the 3D Viewport will place the 3D cursor directly under your mouse pointer.

The view space is used to control the rotation of the 3D Cursor.

For accuracy you should use two perpendicular orthogonal 3D Viewports, i.e. any combination of top Numpad7, front Numpad1 and side Numpad3. That way you can control the positioning along two axes in one view and determine depth in the second view.

By default the depth of the geometry under the cursor is used, this can be disabled using the Cursor Surface Project toggle in the Preferences.
