Miscellaneous Editing Tools

Sort Elements

Reference

Mode:Edit Mode Menu:Mesh ‣ Sort Elements...

This tool (available from the Specials, Vertices, Edges and Faces menus) allows you to reorder the matching selected mesh elements, following various methods. Note that when called from the Specials menu, the affected element types are the same as the active select modes.

View Z Axis

Sort along the active view's Z axis, from farthest to nearest by default (use Reverse if you want it the other way).

View X Axis

Sort along the active view's X axis, from left to right by default (again, there is the Reverse option).

Cursor Distance

Sort from nearest to farthest away from the 3D cursor position (Reverse also available).

Material

Sort faces, and faces only, from those having the lowest material's index to those having the highest. Order of faces inside each of those "material groups" remains unchanged. Note that the Reverse option only reverses the order of the materials, not the order of the faces inside them.

Selected

Move all selected elements to the beginning (or end, if Reverse enabled), without affecting their relative orders. Warning: This option will also affect unselected elements' indices!

Randomize

Randomizes indices of selected elements (without affecting those of unselected ones). The seed option allows you to get another randomization -- the same seed over the same mesh/set of selected elements will always give the same result!

Reverse

Simply reverse the order of the selected elements.

Separate

Reference

Mode:Edit Mode Menu:Mesh ‣ Separate Hotkey:P

At some point, you will come to a time when you need to cut parts away from a mesh to be separate.

To separate an object, the vertices (or faces) must be selected and then separated, though there are several different ways to do this.

Suzanne dissected neatly.

Selected

This option separates the selection to a new object.

All Loose Parts

Separates the mesh in its unconnected parts.

By Material

Creates separate mesh objects for each material.

参考
