Overview

IronCAD

IronCAD provides you with a flexible 3D design environment that breaks away from the constraints of traditional history-based modeling. You can move, resize, and manipulate parts instantly using the TriBall visualization tool, which simplifies complex positioning and alignment tasks. By utilizing both the ACIS and Parasolid modeling kernels simultaneously, you gain the ability to handle complex geometry without the typical regeneration errors found in other platforms.

You can seamlessly transition between 2D sketches and 3D models to create detailed production drawings and assemblies. The software is specifically designed for mechanical engineers and industrial designers who need to iterate quickly on custom machinery or modular equipment. Whether you are creating one-off prototypes or managing large-scale industrial assemblies, you can drag and drop pre-defined shapes from catalogs to build your designs faster.
