Kjartan’s Scripts

Current Version : v0.2.8, Posted 07-May-2016
You can get the scripts here:
KTools Dowload

  • You will find the ktools-menu at the bottom of the Edit Mode W-Specials menu.
  • This addon also sets “Shift+Q” as a hotkey to the ktools-menu (works in both Edit- and Object-mode)

 Cut Tool – mesh.cut_tool

  • context sensitive cut tool
  • cuts based on the currently selected verts, edges or polygons
  • if nothing is selected then it will start up the knife tool
  • options for Number of Cuts, Smoothness and Quad Corner Type
  • also has option for inserting loop cut on the selected edges
  • NOTE: cutting selected polys works best on single strips of polygons



 Build Corner – mesh.build_corner

  • builds corner topology
  • turns N-gons into usable topology (sometimes)
  • good for changing the edge flow of your model
  • preserves UV’s
  • modal operator (works interactively)
  • NOTE: currently only works on one face-region at a time


Snap to Axis – mesh.snaptoaxis

  • snaps the selected verts, edges or polygons to 0 in the selected axis
  • also has option for adding a mirror modifier




Lattice to Selection – object.lattice_to_selection

  • creates a Lattice that scales and orients itself based on the selection
  • “Local” will orient the lattice to the active object
  • works in both Object- and Edit-mode
  • has option for adding the lattice modifier as the first on in the stack
  • currently works only with Mesh objects
  • NOTE: Redo Last (F6) does not work well in Edit-mode. Object-mode works fine


Draw Poly – mesh.draw_poly

  • Shift-Click inverts the face
  • works in both Object- and Edit-mode
  • MiddleMouse gives you a quadrangulated result instead of an N-Gon
  • Ctrl-Click toggles off snapping
  • if nothing is selected then it will create a new object and draw within it


 Quick Bool – object.quickbool

    • quickly carves out the selected objects from the active object with one click
    • also works in Edit mode by carving out the selected polygons (you only need to select 1 vert/edge/face, the tool will “select linked” automatically)
    • has options for Union, Intersect and Difference
    • in Object mode it has options for not deleting the “carve” objects
    • has option for moving the “carve” objects to layer 10 (that is my “garbage layer”)
    • NOTE: this tool uses the boolean modifier, so it works best with manifold meshes


 Auto Tubes – mesh.autotubes

    • creates a tube based on the selected edges
    • options for changing the Width and Bevel Resolution
    • NOTE: this tool will creates a curve w/Bevel. Curves can easily be converted to a mesh with  “Alt+C / Convert to Mesh from Curve/Meta/Surf/Text” (in Object mode)


 Shrinkwrap Smooth – mesh.shrinkwrap_smooth

    • smooths while trying to keep the original shape with a Shrinkwrap modifier
    • great for evening out topology
    • options for pinning the selection border and changing the Shrinkwrap Mode
    • Subsurf option makes the shrinkwrap more reliable, but slower.


 Toggle Silhouette – object.toggle_silhouette

    • turns everything black so that you can evaluate the overall shape (which makes this tool very useful while designing)
    • works in every mode



Paint Selection – view3d.selection_paint

  • Select multiple objects, verts, edges or polys in one stroke
  • Has options for Toggle selection and Deselect
  • Clicking outside of the mesh with Toggle on will deselect everything
  • NOTE: This script will not appear in the menu. Also, having the Toggle option on might cause a delay before the tool starts selecting (on heavy meshes)


Shrink Loop – mesh.shrink_loop

    • shrinks the selected loop
    • works on vert-, edge- and polygon-selections
    • option for shrinking multiple steps at a time.



Path Select Ring – mesh.path_select_ring

    • path select partial edge rings
    • option for interactively picking edges
    • also option for instantly collapsing the selected edges



(the following tools still don’t have GIFs: Grow Loops, Extend Loops, Autosmooth, Calculate Normals and Basic Renamer)

Update history:

v0.2.8 – 07-May-2016
new feature: Lattice to Selection
added a GUI header info to Draw Poly

v0.2.7 – 21-Nov-2015
new feature: Path Select Ring
cut tool will invoke knife in more situations
removed Nearest Vertex option in Shrinkwrap Smooth
added subsurf option (more reliable, but slower results) in Shrinkwrap Smooth
fixed bug in Shrinkwrap Smooth with “cull faces”
fixed bug in Shrinkwrap Smooth if vertex weight was not set too 1
fixed bug in Shrinkwrap Smooth where it would add selected verts to existing vertex groups
fixed bug where menu would give an error if the object was not on a visible layer

v0.2.6 – 31-Oct-2015
new feature: Toggle Silhouette
new feature: Paint Selection
added options to QuickBool for Union, Intersect and Difference
changed DrawPoly to not snap by default
fixed bug in QuickBool where it would remove existing Boolean modifier
fixed obscure bug where the wrong menu would show up in Edit mode if no object was selected but you still had an object active

v0.2.5 – 25-Oct-2015
new feature: drawPoly
fixed selection bug with shrinksmooth
fixed small bug with mirror mod in snapToAxis
fixed bug with with menu where it would fail if there was no active object
quickBool does a “select linked” first, so now you only need to select one face/edge/vert in Edit mode to carve out that piece

v0.2.4 – 19-Oct-2015:
Converted Snap-to-X into SnapToAxis. This tool will now snap to any axis. Also has option for adding a mirror modifier
Added the menu into the W-Specials Edit mode menu
Also added a shortcut to Shift+Q for the ktools menu
RMB-click or Esc while using the BuildCorner will reset the tool

v0.2.3 – 14-Oct-2015:
First version online

NOTE: I’m a newbie at making scripts, so some of these tools will be slow on big meshes (and some might have bugs). Use with care.

Hope you find them useful!

 Custom Retopology (temporarily unavailable)

    • include fuctions for interactive tweaking, extruding, drag-create-face, merge verts, delete, collapse, insert loop and more all within one tool.
    • pre-selection highlighting
    • NOTE: Currently only works with standard blender navigation
    • NOTE 2: The hotkeys will change a bit in future versions

      Hi Raziel. If you want to assign a hotkey to the menu then you can go into “User Preferences/Input/3dView/3dView(Globals)” then you can “add new” input and type in “object.ktools”. Then you can assign the menu to whatever. If you just want to assign hotkey to any of the individual tools then you can just hit “space” then type ktools and then RightMouse Click/Assign hotkey to any of the tools.

    Thanks for very helpful and needed tools!!!

    I have a small problem that I can’t resolve. I’d like to use ‘Paint Selection sctipt’ under the shortcut CTRL+SHIFT+ALT+LEFTMOUSE but in my keymap this keys turn on the persp from ortho view. This is caused by the fact the ‘Emulate 3 button’ option is on. I’d like to use alt key that way but also to use CTRL+SHIFT+ALT+LEFTMOUSE as well.

    I’d like to ask how You resolve this matter? :)

      Hi Darek,
      glad you like my scripts :)

      First of all I do not use “emulate middlemouse button”. If you dont have a proper 3 button mouse then you should maybe consider getting one.
      Second, that option hard codes all combinations of SHIFT, CTRL and ALT + LEFTMOUSE button click as far as I can tell. So that means there is nothing you can do to change the keymap for any of those keys when “emulate middlemouse button” is On.
      But what you can do is to turn that option off and instead create Move, Dolly- and Rotate-View hotkeys manually under “UserPref/Input/3dView/3dView(Global)”.
      Like this:
      Hope that helps!
