We think you’ll be extremely pleased – and impressed - with both the features and the performance of LD Assistant. Powered by Autodesk’s technology, LD Assistant builds on the most versatile, most configurable, and most reliable drawing platform of any application in its class. LD Assistant carries the ‘Powered by Autodesk technology’ logo, which means that you can be assured every file created or edited in LD Assistant is completely native in any AutoCAD software application!

DWG File Format
LD Assistant uses Autodesk’s AutoCAD DWG file format. DWG is the native format for AutoCAD software and AutoCAD-based products. Autodesk owns, develops, and iterates the DWG file format.

The DWG format changes every few years, as Autodesk adds new features to AutoCAD.

Several reverse engineered software libraries exist that simulate the DWG file format with various levels of success in providing DWG read and write capabilities.

With nine million users and over a billion AutoCAD DWG files in existence, no wonder other CAD software companies want you to believe that they can import and export to DWG without any problems!

Designed to perform on today’s desktop and portable systems, LD Assistant users are already seeing outstanding output from current PC technology. And while you’ll be perfectly happy with the performance on a standard system, LD Assistant is designed to take full advantage of the top-of-the-line computers of today - and tomorrow!

While some companies still limp by on the single-processor concepts of the last decade, we have optimized LD Assistant for multi-core and multi-processor operations. By taking advantage of Quad-Core Processors, LD Assistant grows with your computer, grows with your designs, and grows with you. When it comes to rendering and animation, you will leave your competition in the dust.

Rendering, Raytrace and Radiosity
Advanced rendering techniques allow users to render highly detailed and photorealistic images. Ray tracing traces the path of rays sampled from the light source. Reflections and refractions generated this way are physically accurate. Indirect illumination techniques, like global illumination and final gathering, enhance the realism of a scene by simulating radiosity, or the interreflection of light in a scene. Final gathering is an optional, additional step used to improve global illumination (GI). It increases the number of rays used to calculate GI to smooth out and eliminate adverse lighting artifacts.

2D Drafting
Powerful 2D drafting tools are at the core of LD Assistant, so you can draw full ground plans. LD Assistant has a built-in database with work sheets for producing paperwork and equipment lists. The same 2D & 3D tools found in LD Assistant are used by 9,000,000 designers and architects to create their working drawings.

3D Modeling
3D tools include true Boolean operations, extrude, extrude along path, revolve, 3D array, 3D Orbit and other high-end 3D CAD features. On-line tutorial and tech tips make it easy to start drawing objects in 3D.

Real-Time Pre-Visualization
LD Assistant comes with built-in support for 64 DMX-512 Universes, and can both send DMX and receive DMX through a dongle. Lighting consoles and lighting systems can be connected using Pathport Ethernet, Art-Net Ethernet, Art-Net Parallel, LD-Net USB, ENTTEC Ethernet, ENTTEC Open USB & Pro USB dongles. Once a plot has been created, the design is opened (with one button click) in LD Control, a real-time visualizer for pre-cueing and testing designs. Save thousands of scenes and cues within a single DWG file. Create AVI movies with the push of a button.
