## Terminology
|
||||
|
||||
For purposes of the BOSL2 library, the following terms apply:
|
||||
- **Left**: Towards X-
|
||||
- **Right**: Towards X+
|
||||
- **Front**/**Forward**: Towards Y-
|
||||
- **Back**/**Behind**: Towards Y+
|
||||
- **Bottom**/**Down**/**Below**: Towards Z-
|
||||
- **Top**/**Up**/**Above**: Towards Z+
|
||||
|
||||
|
||||
## Common Arguments:
|
||||
|
||||
Args | What it is
|
||||
-------- | ----------------------------------------
|
||||
rounding | Radius of rounding for interior or exterior edges.
|
||||
chamfer | Size of chamfers/bevels for interior or exterior edges.
|
||||
orient | Axis a part should be oriented along. Given as an XYZ triplet of rotation angles. It is recommended that you use the `ORIENT_` constants from `constants.scad`. Default is usually `ORIENT_Z` for vertical orientation.
|
||||
anchor | Side of the object that should be anchored to the origin. Given as a vector towards the side of the part to align with the origin. It is recommended that you use the directional constants from `constants.scad`. Default is usually `CENTER` for centered.
|
||||
|
||||
|
||||
## Examples
|
||||
A lot of the features of this library are to allow shorter, easier-to-read, intent-based coding. For example:
