G-Lasso Draw

Very fast Make polygon with lasso of Grease pencil.

It is useful for creating a rough model and getting inspired.


Knowing the same function of 3D-Coat, I tried to create this add-on as verification to reproduce with Blender.

This is an interesting tool if you actually use it!

CurveTube setup

In order to make a curve tube, it is necessary to make some settings.
It is a function to set up this at once and create an empty curve object.
It will be useful when you want to make a tube quickly.
(It is another function from G-Lasso.)

  1. “CurveTube setup” Button creates an empty curve object
  2. You can quickly create a team with Curve’s Draw tool etc.
  3. You can adjust the parameters of the curve object in the Curve panel
Option

Option

  • Mirror modifier
  • Subdivision Surface Modifier
  • Resolution
  • Radius size
  • radius resolution
  • Fill mode
  • writing pressure

Menu

  • To see tube related settings of the selected curve object
    • Resolution
    • Radius size
    • radius resolution
    • Fill mode
    • Effective / ineffective writing pressure

Use Addon

Although it is not required, it is necessary addon to use some functions.

  • Bool Tool (Blender’s built-in addon)

looks absolutely wicked! Can you show topology of this piece?

Can’t wait for a 2.8 version!

Good idea for an addon. Is this a modal addon? I cant tell based on the video

Does this use booltool poly draw?

nice try 79 haha. Come to 2.8 and we will party together!

It is not made in Modal.
This tool is created by “Macro”.
The behavior performed by this tool is very simple.

Workflow

  1. Set the cursor to the mouse position
  2. Drawing grease pencil
  3. Convert grease pencil stroke to polygon
  4. Create face
  5. Set Mirror modifier
  6. Set Solidify modifier
  7. Delete grease pencil layer

No. This tool does not use “booltool poly draw”.

The topology of object created with this tool looks like an image.

Wow, nice idea! It could be used nicely for blocking. Then sculpt and detailing. Need to try it tomorow. Would be nice to have this addon for 2.8 too.
(A dream would be to have in addition to creating also cut away the geometry with grease pencil, for fast refining the big shapes)

Nice, so you actually can use it with booleans, to some extent.

Note: How To Draw Poly Stroke

  1. Draw Poly Stroke G Pencil in advance
  2. If you run G - Lasso Draw and “Escape key” it “without drawing anything”
  3. A model of Poly Stroke is created.


Really Cool…
Waiting for 2.8

This addon is SUPER awesome because blocking in shapes is so much faster and intuitive this way. In 2.8 with the Grease Pencil stroke placement/snap controls it will be even more awesome. I can see using this Addon all the time. Great work man!

G-Lasso Draw.py Blender 2.8 update!

In Blender 2.8, the specification of the Grease Pencil has been changed drastically.
Therefore, it behaves differently from Blender 2.79.

▼ You need to run G-Lasso Draw twice.

  • When not in Grease Pencil “Draw mode”

    • Create a Grease Pencil object
    • change to the Grease Pencil “Draw mode”
    • Make the stroke ready to draw immediately
  • In case of Grease Pencil “Draw mode”

    • Convert Grease Pencil strokes to polygons
    • An error will be displayed if nothing is drawn
  • In Blender 2.8, you can create circular shapes and box shapes from the left toolbar

Holy cow, this is incredible! Works like a charm!

Already buy it :slightly_smiling_face:
Thanks,
It’s not expensive, incredibly intuitive, and super usefull one of the best add on …

Btw, maybe there is a chance to make solidify thickness interactively controllable? Something like if user press ctrl+shift+V when confirming shape, it would automatically adjust thickness looking at cursor position, without any additional clicks.

Thanks a lot for this nice addon. It’s so easy to doodle around, then join the shapes and then remesh with openVDB, etc. These kind of tools let’s you create what is in our head instead of pressing buttons and let something else create for you. So for me such addon has very high priority.

Whoa, that looks good!
Maybe some short demonstration would be beneficial, because there’s so many new functions and I have no clue how it works.

Btw, is it asking for Loop Tools? Weird, it’s enabled:
