DEWALT Design Assist (DDA) is a free, comprehensive structural design software focused on the calculation and selection of anchoring systems for concrete and masonry. It allows engineers to perform code-compliant designs according to the latest ACI 318, CSA A23.3, and IBC standards, covering a wide range of mechanical, adhesive, and cast-in-place anchors. The software features a dynamic 3D interface that provides real-time feedback as users adjust parameters such as edge distances, spacing, and base plate dimensions. It supports both standard and custom anchor patterns, ensuring flexibility for various structural connection scenarios including cracked and uncracked concrete conditions.
Beyond its calculation engine, DDA enhances engineering productivity through its robust reporting and project management tools. Users can generate detailed, professional PDF reports that include step-by-step calculation proofs and code references, making it easy to verify compliance for submittals. The platform is available as both a web-based application and a downloadable desktop version, allowing for seamless project saving and sharing. As a free resource, it provides high-level functionality for anchor design, including a “Product Search” feature that helps users compare multiple products simultaneously to find the most cost-effective and structurally sound solution for their specific project requirements.
