This is a modeling tool for Blender 2.79 and 2.80 that lets you use curves to deform your mesh, allowing you to make beautiful shapes.
It's useful for blocking and polishing forms of organic and hardsurface meshes.
- Projection selection mode
- Sequence selection mode
- Curve grab mode
- Editing a plane
- Editing a cube

How to install
On Blender, go to File > User Preferences > Add-ons, then press the "Install Add-on from File" button. Select the ZIP file that you downloaded from Gumroad to install it (choose the appropriate version for your Blender).
After installed, tick the add-on checkbox to enable it, and save your user preferences.
How to use
It's very simple: you select two or more vertices where you want the control points of the curve to be, then activate this tool.
A curve will appear and you can grab / rotate / scale its control points. When you do that, the mesh will follow along.
When you're done, hit Enter to confirm or Esc to cancel it.
- You can also use this tool by selecting a sequence of connected vertices. Just make sure your selection doesn't loop.
- You can also start this tool without selecting any vertices, leading you to the "projection" mode where you can click to set where the control points of the curve should appear (example).
There are some default keys that you can use while the tool is on (you can see / change all of them in the add-on preferences):
- (Q) Use Extremes: toggles the deformations caused by the start and end control points of the curve. This is best used when either of the ends of the curve starts from a sharp turn of your mesh.
- (E) Use Direction: toggles the use of the curve orientation (tangent) to deform the mesh, in addition to using its position.
- (PageUp / PageDown / W) Falloff settings: lets you change how the curve affects nearby vertices, much like Blender's Proportional Edit mode (aka "soft selection").
- Include support for the Cmd modifier key so that Undo can be used on macOS systems.
- Add a preference to disable grab-mode and/or change the modifier key (only Ctrl, Alt and Cmd [Mac OS] available).
- Add a preference to set knot handle types to "Vector" after a Snap Straight operation.
- Improved the grab mode behavior on key release.
- Fix for a hidden collections bug, now the curve is always put in the master collection.
- Fix for when using the Distance / Connected falloff modes and some startup-snapping modes.
- Fix for when any mesh modifiers are set to show in the viewport but not in Edit mode.
- Fix for when the falloff is set to zero and the tool confirmed.
- Fix for a rare snapping bug.
- Fixed a bug when using the projection mode with the snap startup modes.
- Added an option to use double-clicks of the "select" mouse button to confirm / apply the tool.
- Added a more robust right-mouse-button setting with three choices of behavior.
- (2.80 only) Fix for when the internal curve is in a different collection than the mesh.
- Minor cleanups.
- Fixed a keymap operator name, changed after a 2.80 build.
- Added a new snapping method, "Smooth / Straight Proportional".
- Some other minor fixes.
