Face Cutter

by KushiroCG in Scripts and Addons


Face Cutter is a handy modeling tool designed for cutting ngon face easily.

It allows you to cut perpendicular lines (or rotated) on selected face, by easily defined snapping points.


  • Set number of divisions (snapping points), then cut by lines.

  • Ability to cut through the whole mesh (using blender's Knife projection API)

  • Define a cut-line by two points

  • Rotate a cut-line by angle

  • Align a cut-line by any nearby edge.

It is a very convenient tool for general modeling task. It provides better functionalities comparing to original blender's K knife tool. Also, it is similar to Ctrl R in blender, but this tool works on ngons too.



Usage

Edit mode >  Select a face or multiple faces

Then right-click to open Context Menu, choose "Face Cutter" at the bottom of the menu.



Basic Cut

Select an edge (highlighted by yellow), then you can set "cutting lines" on the snapping point, or anywhere.

You can increase the number of snapping points by Ctrl + mouse wheel scrolling. (or you may use square bracket keys (the [ ] keys)).

After setting the cutting points, you can press Q key to execute cutting.

Note : You can hold Shift key anytime to turn off the snapping.



Cut through

In order to cut through the mesh, press R key to execute the cutting.

You can also press Shift + R key to limit the cut to linked faces only.



Fill Lines

You can quickly fill all the snapping points with lines by F key.



Rotate the Line

Z key or X key : Rotate the line by 5 degree.

C key or V key : Rotate the line by 1 degree.



Align the line to edge

You can align the line easily by pressing A key.

Just move your mouse cursor near an edge, then press A key.

To revert the line to original angle (perpendicular), move your cursor to your original selected edge then press A key.




Full Width Mode

When you work on multiple faces, sometimes you want to use the full side instead of small edge segment. You can press W key to toggle Full Width Mode.

In Full Width Mode, the tool will try to use the full side (all co-linear edges).



Multiple Cutting Lines

You can create multiple cutting lines based on different edge.

The tool allow you to create some cutting-lines on one side, then Press Esc key, to return to "Edge selection" state, then select another edge for the base, and then create new cutting-lines again. After all the lines set, press Q or R key to execute.



Undo

You can press Ctrl + Z key to undo a cutting-line (remove last added line). (below is the screenshot of tool hint text)



Symmetric Copy

You can easily copy all the cutting lines to another side by pressing S key.

If will copy all cutting lines as mirrored.


Cutting Corner (45 degree shortcut)

You can set the line rotation to 45 degree by just pressing D key. Pressing D key again will set it to -45 degree. It is convenient for cutting corners.



Easy Edit Mode

You can press E key anytime to switch into Easy Edit mode.

In this mode all snapping points will show up, you can just click the points to create cutting line easily. This is a powerful way to create diagonal cutting lines between multiple edges.

Press E key again will exit the mode.




Number key for Snapping Points

You can press Number keys 1-9 to set the number of snapping points directly.




Cut on multiple Non-planar Faces

When you selected faces with different normals (non-planar), you can still cut and the cut will be "projected" onto the faces. When you select a base edge, you need to choose one face for alignment (just move the cursor to near it).



Cut + Break Apart

You can press T key to cut-through the mesh and then break apart into solid pieces.

Also you can press Shift + T to limit the cut+break only on linked geometries.
