CCAD Software enables precise conceptual modeling.

Press Release Summary:

Concepts Unlimited Conceptual Computer Aided Design (CCAD) tool offers modeling, rendering, animation, and automated drawing generation tools. Focused on conceptual and preliminary design, software creates NURB and analytical data that migrates into existing engineering solutions and keeps original design intent intact. Hybrid modeling techniques, integrated through geometric associativity, automatically capture design intent and enable modifications and iterations.

Original Press Release:

CSi Concepts Unlimited Now Available

Industry's First Complete Conceptual Computer Aided Design (CCAD) Tool

Fort Worth, TX October 6, 2003 CSi last week released its new flagship product, Concepts Unlimited. Offering easy to use modeling, rendering, animation, and automated drawing generation tools, Concepts Unlimited provides the ideal solution for conceptual designers supporting the MCAD and Enterprise communities.

Precise Conceptual Modeling

Concepts Unlimited is one of the industry's first modeling applications focused on conceptual and preliminary design for those requiring precision content. Unlike faceted based conceptual tools, Concepts Unlimited creates precise NURB and analytical data that migrates smoothly into existing engineering solutions keeping the original design intent intact.

Concepts Unlimited integrates a combination of hybrid modeling techniques including wireframe, surface, and solid modeling through geometric associativity which automatically captures design intent and enables rapid modifications and iterations. Based on the state of the art ACIS R12 modeling kernel, data can be confidently shared using SAT, IGES, STEP, and CATIA V4 file formats.

Rendering and Animation

Integrated photo realistic rendering and animation is a must for communicating and taking your conceptual designs to the next level. Using our drag and drop materials library, you can create high resolution, ray traced, poster size JPEG, BMP, or EPS files as well as QuickTime flyby, walkthrough, and VR animations.


Where MCAD and Enterprise solutions focus on providing endless functionality, Concepts Unlimited focuses on usability first. The simple user interface is as easy to learn as many of the 2D vector graphic programs currently used for conceptual design.

Automated Drawing Generation

Designers can use automated 3D to 2D tools to generate 2D drawings from surfaces or solid models. The resulting drawings consist of precise curves (lines, arcs/circles, ellipses, splines) that are projected and trimmed for visibility within drawing views. Drawings can be annotated using a variety of dimension tools and shared with others using DXF/DWG or Adobe Illustrator file formats.

Pricing and Availability

Concepts Unlimited runs on multiple platforms including Windows 2000/XP Professional and Macintosh OSX and lists for $3000. Special introductory rates are available through international resellers listed on our web site at
