Autodesk

Autodesk software is primarily used for creating 2D and 3D designs, visualizations, and simulations across various industries, including architecture, engineering, construction, manufacturing, media, and entertainment. They are also used in education and for consumer-level creative tools. 

Forma Data Management (formerly ACC) refers to the suite of cloud-based construction management software offered by Autodesk - Forma Build, Forma Data Management & BIM 360 etc. - that connects teams, workflows, and data across all phases of a building project. It aims to improve collaboration, reduce risks, and maximise efficiency for construction projects, from design to operations. 

BIM 360 is a separate solution that was combined with PlanGrid, along with several enhancements, into Forma Build (previously Autodesk Build)
