Acme CADSee can run in one of two modes: 1. Browse window presents an Explorer-like interface that allows you to locate and manage images stored in your file system. This is the default mode when you start Acme CADSee. 2. View Window allows you to view a selected sequence of drawing, one at a time. This is the default mode when you double-click on an drawing file in Explorer to view it in Acme CADSee.
