# Version 319

## Feature Updates

### 3D performance boost

Improvements have been made that have resulted in 5-10x faster performance when viewing larger 3D layouts.

### Updated keyboard shortcuts

Support added for the `+` and `-` keys in the numpad and both `Shift` keys.

### Logic changes for more intuitive cuts 

Behind the scene changes were made so that adding/deleting splices will result in more intuitive auto cuts. This also makes actions like changing the size of a member or chord react in a more predictable manner.
