The 12d Model Project Launcher is a new Version 15 (and above) option added to enhance the access and opening of your 12d Model Software projects in just a couple of simple clicks.
The panel has been developed to work both on standard PC and smaller handheld tables in the field. The loading of various 12d Model Themes to tailor the user experience and menu structure is just one of many benefits with the new launcher.
12d Model 15.0 Water Engineering: Any PROJECTS opened, modified and/or saved with V15 can not be opened with V14 or any earlier versions of 12d Model.
IMPORTANT – Options Logs being stored and emailed back to 12d Solutions
At the end of each 12d Model 15 session, an Options.txt file is emailed back to 12d Solutions.
This is the same file that is sent back when you have a crash in V15.
To see what information is in the file, the file is also saved in the folder options_logs in your Working Folder.
To turn off options logging and NOT EMAIL the log file back to 12d Solutions, set the env variable USE_OPTIONS_LOGFILE_4D to 0.
Comprehensive notes for installing 12d Model 15 and all the links to the required files are given in the Installing 12d Model 15 Installing Release Version pdf, including links to Getting Started Guides:
Introduction to the 12d Model Programming Language (12dPL)
The 12d Model Programming Language (12dPL) is a powerful scripting language designed to run directly within 12d Model. Originally known as 4DML when the software was called 4d Model, 12dPL enables users to extend and customize the functionality of the 12d Model environment by writing their own programs.
Language Foundation and Features
12dPL is based on a subset of C++, enhanced with specialized extensions that simplify the manipulation of 12d Model data. It includes a comprehensive library of intrinsic functions covering most aspects of civil engineering modeling—from geometry and survey data to design and analysis tasks.
A key design principle of 12dPL is its seamless integration with 12d Model’s ability to “stack” incomplete operations, allowing users to pause, resume, or modify workflows interactively.
Purpose of This Manual
This reference manual does not teach general programming techniques. Instead, it provides:
- The syntax and rules of 12dPL
- A complete listing of built-in functions
- Usage examples for many of these functions
It is assumed that the reader has a basic understanding of programming concepts, though prior experience with C++ is not required.
