Creating technical illustrations is the main purpose of Zea Illustrations. Most of the time, we expect you will either export the views you create as 2D images for product documentation or publish interactive 3D views directly to the web.
3D models are shared across apps on the Zea Platform. The 3D models synced via Zea Sync can be used in Zea Illustrations for technical drawings and in Zea Parts to build an interactive 3D parts catalog.
