Great news for AutoCAD users!
The previous formats including IFC 2x3 format are also available, this way OrthoGraph supports the most CAD formats to be written directly from the iPad.
For ArchiCAD and Google SketchUp users there is no change, they can download and use the respective desktop converters/extensions that work with OrthoGraph's native SRVD file format.
Freehand Annotation drawings on the floor plan are also a new and highly requested feature. Create notes, markings, descriptive drawings within your floor plan for later reference. There are two different brushes with 4 sizes and several colors for creating annotations. Annotations are always connected to the actual room you are working on, but when switching to 3D view, then all annotations will fly as they were drawn on the whole drawing.
