eDrawings® Pro is the professional 2D and 3D CAD collaboration app for the iPad, iPhone and iPod Touch that can view native SolidWorks® files (part, assembly, drawings), eDrawings files and DraftSight® (DWG™, DXF™) files. You can easily view models and access configurations, drawing sheets, and exploded views for eDrawings files published from SolidWorks and all other supported CAD software. Markup! Measure! Section! eDrawings® Pro takes you to the next level of 2D and 3D collaboration with more functionality, including dynamic cross section views, measurements, markups & annotations and the unique ability to share it all by email! eDrawings includes Augmented Reality (AR). This allows you to view your 3D models in 1:1 scale into the real world. By simply activating the device’s camera, you can bring your virtual 3D designs in a real context and see them in situ, sitting on your desk or on your conference room table or even in the palm of your hand, through your iPad, Pad mini, iPhone or iPod Touch’s screen. Move around the room and see your design from any perspective. With an intuitive user interface, eDrawings® Pro enables you to dynamically view cross sections of your models in XY, YZ, or ZX directions from both sides and easily drag the cross section plane on screen or with a convenient slider. You can also measure distances in your designs, with easy-to-use selection filters for faces, edges, vertices and holes. With eDrawings® Pro you can create markups on your drawings, including text notes, freehand notations, dimensions, cross-section views, photos and camera snapshots. You can share your marked up eDrawings files with others for review and further comments. All markups with history are saved within the eDrawings file.
