Simple Bend is a handy tool for bending sub-divided mesh.
You add the edge-loops or sub-divide your mesh
Select the faces for bending (it can be all faces of just the middle parts)
Run the tool, Drag on the yellow axis to bend.
You can bend the selected mesh easily by dragging on the on-screen axis.
Also you can bend the select part only, and let the connected geometries to follow. (Press C key to choose the part)
Edge Axis mode
This is the advanced mode for Simple Bend. It is very useful for bending at any self-defined angle.
It works as follow :
The tool read your “last-selected edges” for its bending axis and direction. It needs two edges, and they mush not be co-linear (same direction).
In order to use this mode, you have to switch to Blender’s Edge mode, select the part, hold the Shift key, then un-select the “2 edges”, then re-select the “2 edges” (this procedure will make those edges to become the last selection in blender), then run the tool.
You may watch the follow gif for simple understanding :
Please note that, from the above gif, when you select the last two edge, the selection order is important :
First edge : Mesh direction.
Second edge : Bending direction.
They have the following meaning :
(When you run the tool, you can also press the W key to swap the axis. )
=== Please watch this tutorial :
Blender Edit mode > Switch to Face mode or Edge mode.
[Basic mode] : Use Face mode to run the tool
[Edge axis mode] : Use Edge mode to run the tool
Right click on the 3D viewport, then select “Simple Bend” at the bottom of the pop-up menu (blender’s context menu).
On Screen Key
S key : Only modify the selected vertices. it can be useful when you only select the surface of a mesh, and you want to bend the surface manually.
W key : Swap the bending Axis. It will change the bending direction.
C key : Bend only one side instead of bending both side. Press C key repeatedly to switch between different part.
Q key : Confirm the bending
Shift key : You can hold Shift key to snap the bending amount to 5 degree unit.
After bending the mesh, press Q key to confirm.
Improved the support for different mesh size (it will auto scale the Axis)
Fixed a bug for empty faces selection
Improved the on-screen Axis for small mesh / thin surface, now it has a minimum length
W key now only works on Edge-Axis mode (avoid confusion)
S key (select-only) status will not be prevered now.
