Bug fix

  • Fixed the problem that failed when trying to execute polygonization in grease pencil draw mode with no object selected.

Demo Model

It is a model created while developing the add-on.
A model created using G-lasso Draw ver1.3.2.
Other than that, most are created by position adjustment in basic operations and shape adjustment in duplication and proportional edit.


Sweet, thanks!

When you enable and disable this addon, it adds another set of hotkeys to the keymap. I’d like to make a workspace for this so it’s going to turn on and off on it’s own and it shouldn’t do this.

edit: Well I guess the addon isn’t disabled/enabled when you change Workspaces. :frowning:

Trying this in 2.8, but it kinda doesn’t work unfortunately. Do you have a step by step video explaining the features or some documentation? Maybe it just needs to be updated? Thanks!
Edit: Nevermind I think I figured it out. ‘Running twice’ means hitting Shift-V before and after drawing the stroke.
Edit: accidental heading

I like the addon, but sometimes I have to uninstall it because shift+V is also to get to the vertex menu in Edit mode, and if you edit Text and want to type a capital V you have to press shift+V as well (or capslock). An addon like this where you can sketch your ideas is quite important to me.

ver1.6.0 Enhanced convert polygon function / G-Thinkness Gesture

New How To Video

Japanese language

Enhanced convert polygon

Added option to create separate strokes

Multiple strokes can be polygonized as separate objects.
This new option [Separate Stroke] is enabled by default.

You can switch from the post configuration option.
Use it disable when you want to create one shape with multiple strokes.

Change origin setting to geometry


Added “Geometry” to the origin option and made “Geometry” the default.
This makes it easier to fine-tune by rotating it in object mode.

Changed default option settings

Changed mirror off by default .
If you want to mirror at a specific position, set the mirror target object.

  • Changed the default origin to geometry
  • Changed mirror off by default
  • Changed the layout of the main menu a little and displayed the menu for setting the object to be mirrored at the top
  • Enable Separate Stroke by default

Apply Rotate can be used even if the origin is not a cursor

Apply Rotate is disabled by default.

Added option to Remove grease pencil as after creation

You can now choose whether to delete the grease pencil object after creation.

Added option to remove unconnected parts in remeshing modifier

Added [Use Remove Disconnected] option to remove remeshing modifier.
[Use Remove Disconnected] is disabled by default.

G-Thinkness Gesture enhancements

Enhanced G-Thinkness Gesture (Shift + ctrl + V) to support multiple objects and add modifier removal.
It became a multifunctional auxiliary tool that can adjust modifiers, change objects, change add-on settings, etc.

Supports multiple objects

You can perform batch operations such as adjusting the width of the solidification modifier and adjusting the smooth modifier.

Bug fixes

  • [FIX] Fixed an error when selecting objects are merged when voxel remeshing (B key) is executed.
  • [FIX] Fixed an issue that could not be adjusted immediately after setting smooth modifier with S key.

Adding a keymap

Modifier removal is now possible.

  • Ctrl + C changed from [Origin To Curosr] option to [Copy To Option]
Keymap function
Space / Enter Confirm
Alt + D Remove solidification modifier
Alt + S Remove smooth modifier
Alt + N Remove skin modifier
N Skin modifier mode The thickness of the skin can be adjusted by moving the mouse left and right. Processing is heavy
T Tube stroke / Create grease pencil object
Ctrl + C Copy To Option Copy active object modifier settings to add-on option settings
( Changed from switching the “Move origin to cursor” option )


  • Disable auto-set solidification modifier at runtime by default
    • Can be activated from Menu → Operator → “Add Solidify in advance”
    • If you want to quickly set the solidification modifier, use Ctrl + Shift + V to execute it immediately → D key
    • As G-Thinkness Gesture has been used for other purposes, it has been disabled in consideration of cases where you do not want to set solidification.
  • Change the offset to 0 when setting solidification modifier with D key

Added the following buttons to the modifier menu

Basic operations of modifiers can now be performed in the menu.

  • Render / Viewport switching
  • Order move button
  • Apply / Delete

Copy To Option

You can copy the modifier settings of the active object and set them as add-on option settings.
This is useful when you want to adjust the thickness of the polygon to be created in the future, mirror settings, etc. to the active object.


Transform Apply & Set Origin

Added the function to apply transform and set pivot. Apply scale and rotation, and set the origin position to the object position set as mirror target.
When the origin setting option is geometry, applying a mirror modifier solves the problem that symmetry editing does not work well in sculpt mode.

  • Added ability to apply transform and set pivot
  • Added similar options for voxel remeshing post-configuration options

Added warning display

When there is no grease pencil layer, active frame, stroke, etc., when trying to execute G-Lasso Draw polygonization, the execution is stopped, a warning is displayed, and error log is not output.


  • When G-Lasso Draw is executed from the menu, the cursor is not set automatically.
    • Fixed an issue where the cursor was placed at the back of the menu when executed from the menu
  • Since the menu option classification items have increased, auxiliary options that are not directly related to polygon creation have been classified as “Assistant” .

Other-Bug fixes

  • Fixed an issue where panel category changes in add-on settings could not be saved
  • Fixed an issue where Weighted Normal modifier would not be set without using bevel

This is looking better and better! Great work. Hit me up if you ever want to brainstorm ideas together :slight_smile:


Just wanted to thank you for your amazing work on this addon/workflow, it’s so easy to use AND to customise for every needs. Ps. It would be a dream to see you and alksndr working together on anything: new addon, a combo of what you already have, etc. I’m a huge fan of creative/artistic/hands-on tools like you’re doing, they make Blender super intuitive and especially fast for any artistic decision on the fly, like drawing with a pencil on paper.

Well, that said thank you guys for your hard work, really.

Is that just me, or when Remesh modifer is enabled, sometimes boolean split and difference doesn’t work? It seems to make an edge cut, but doesn’t divide objects themselves.

Most of the time I don’t use separate stroke option, How can I make off by defaut ?

I missed the comment in this thread for a while. I’m sorry.
To turn off the “Separate Stroke” option, you can access it from the red box below

We have arranged the menu.

  • Added Japanese translation
  • Removed some icon menus to improve visibility
  • Curve settings that were in the operator menu have been separated into separate menus
  • Renamed the main tab from “Active Object” to “Main”

Greatly improved Boolean function

Implemented the Boolean function independently.
The BoolTool add-on is no longer needed and many options have been added.
You can create hard surface models that take advantage of Booleans.

  • You can use Intersect, Union, Difference, Slice
  • Utilize remesh modifiers and join booleans to create non-destructive meshes


  • If not in Grease Pencil Draw mode, create a Grease Pencil object so you can draw strokes immediately
  • If two or more objects are selected, the active object is the Boolean target object and the other selected objects are the Boolean objects.
  • Handling Boolean objects
    • Created in the “Cutters” collection
    • Box display, rendering hidden
    • For grease pencil objects, it will be polygonized
    • In the case of difference, it is three times as thick as the target object in order to hollow out the target object.


  • Parent
    • Parents the created object to the Boolean target object
  • Automatic smooth
    • Boolean target objects are automatically smoothed
    • In case of difference, it will be automatically enabled
  • Smooth (sort modifiers)
    • Place the additional Boolean modifier below the remesh or subdivision
    • It will be a smooth mesh
    • If this option is off, you get sharp edges
    • If Boolean mode is diff, it is disabled by default
  • Sort under the bevel modifier
    • Place the Boolean modifier you want to add below the bevel modifier
  • Fixed Boolean object
    • Always boolean to the same object
    • You can access it from Main → Boolean → [Fix Object]
  • Application
    • -Apply a Boolean modifier to Boolean objects and remove Boolean objects

Apply Boolean

Created a function to help apply Booleans.

  • If a Boolean target object is selected, apply all Boolean modifiers and remove the Boolean object.

    • This setting is an add-on setting. Save add-on settings if you always want to hide
  • Organize and improve source code internally
  • “Add Solidification Modifier Before Execution” option moved to Add-on Settings
  • Fixed a problem that Voxel shortcut display was V instead of B


You can create a curved tube that reflects the writing pressure of the grease pencil.
Other functions also correspond to the curve object.

  • If there is only one selected object, the cursor will be the center position
  • If there are two or more selected objects, the active object position will be the center position.

You can adjust the count from the menu even after setting.

  • Main → Operator → Changing the count value under Array Duplicate radially adjusts the count value of the Array Duplicate modifier for the selected object and the rotation value of the target object

Voxel remesh

  • Added voxel size setting

thanks :slight_smile:

This is absolutely incredible, thanks for the update!

I don’t understand the new way of boolean cut with 1.7, before its was incredibly fast but now i’m lost.
I make a video
how can I reproduce de 1.6 behavior ?

Edit after some test it’s ok I just need to draw differently expand a little the stroke.
nice job.
