# VF Radial Offset



This add-on was designed for Blender version 2.8-4.1 (though not all previous versions may be fully supported). For Blender 4.2 and onwards, [please see the new Mesh Kit extension](https://github.com/jeinselen/Blender-MeshKit).



Offsets vertices radially to better preserve bevels and other spatial relationships, as opposed to scale.

One, two, and three dimensional modes support different needs.

## Installation and Usage

- Download [VF_radialOffset.py](https://raw.githubusercontent.com/jeinselenVF/VF-BlenderRadialOffset/main/VF_radialOffset.py)

- Open Blender Preferences and navigate to the "Add-ons" tab

- Install and enable the Add-on

- It will show up in the 3D view `VF Tools` tab



## Settings



- `XYZ Values`

	- Individual inputs per axis, allowing for 1D, 2D, and 3D functionality

		- See below for examples of how 1D, 2D, and 3D radial offset differs from simple scaling

	- Using dissimilar values can create ovoid results while still preserving the spatial relationships of vertices that are radially inline

		- This will not work with bevels in 3D mode, but offsetting in two dimensions will retain bevels that are aligned with the third axis

	- Positive and negative values will determine if vertices are offset away from or toward the centre of the model

- `Radial Offset`

	- Click this to calculate vectors and offset each vertex in the defined direction



## One Dimension



![screenshot of the Blender 3D view interface with the add-on installed, showing one dimension entered](images/screenshot1d.png)



Setting only one axis to a non-zero value will offset vertices in that one direction, splitting them at the model's centre point without stretching the sides.

## Two Dimensions



![screenshot of the Blender 3D view interface with the add-on installed, showing two dimensions entered](images/screenshot2d.png)



Setting two axes to non-zero values will offset vertices in a circular pattern, best used for changing the size of watch faces, columns, and other cylindrical shapes without changing bevels aligned with the third axis.

## Three Dimensions



![screenshot of the Blender 3D view interface with the add-on installed, showing three dimensions entered](images/screenshot3d.png)



Setting all three axes to non-zero values will offset vertices in a spherical direction, best used for scaling spheres while preserving the local height of surface details.

## Known Limitations



- Does not work on objects with shape keys

- When multiple objects are selected, only the _active_ selected object is affected (does not support batch processing multiple models)
