# Avontus Designer 2015 R12

### **Version: 3.4.173.0 Release Date: November 2, 2015**

## New Features

- You can now attach other parts to a specific part using a new 'IncludePartNo' custom property in the Material Master. These new parts will automatically be added to the Bill of Materials when displayed.

## Enhancements

- The Cup system nodes now appear in the model view more like the actual cup connection.
- Lattice girders now draw with an internal diagonals member in the 3D model.

## Issues Resolved

- Auto-save now runs in the same process as the main form and blocks the UI controls to avoid running other commands. This avoids a conflict with the auto-save process.
- Database save issues (e.g. concurrency and update errors) have been fixed.
- The wait form now blocks ribbon and other UI controls while shown to avoid interacting with the program while another process is running.
- Fixed an issue with incorrectly calculating live load for multiple bracket bays.
