SketchUp Pro is compatible with a decent range of file types including AutoCAD's DWF and DXF files. You'll also be able to use 3D printing STL files, PDFs and image files using this software. Additionally, SketchUp Pro has a mobile app, which allows you to organize and view your models from your phone.

Hi parker, Unfortunately there is no official Google Sketchup for 3D designing especially for iPad, it's not possible to design using this software on Apple products but to make it easier for you there is some apps that make viewing 3D Sketchup files possible on the iPad or iPhone such as SightSpace 3D.
