The first step in model documentation with AutoCAD 2012 is to create a base view of your 3D model. It's easy! The new Base View tool creates a 2D view from the 3D solids and surfaces in modelspace. If there are no surfaces or solids in modelspace, you can select an Inventor model (ipt, iam, or ipn file).
The Base View tool automatically displays a scaled preview of the model at the cursor. As you place the base view on the drawing layout, you can specify options such as type, orientation, and scale.
A contextual ribbon tab displays relevant controls, which vary depending on the source of the model, AutoCAD's modelspace or Inventor.
If an Inventor model is the source for the base view, an additional panel is displayed in the Drawing View Creation ribbon tab, enabling you to further control the representation of the model.
If the Type option is set to Base and Projected, rather than Base Only, you can automatically create projected views after placing the base view. Simply drag the cursor to the desired location. AutoCAD automatically creates the appropriate view based on eight standard view projections: four orthographic and four isometric. You can continue adding projected views later using the Projected View tool.
Each view creates a new Drawing View object that includes a boundary similar to a viewport but doesn't print. An icon in the status bar tray indicates when a drawing contains drawing views. You can view and modify properties for a selected drawing view using the Properties palette or double-click on the drawing view to access a context-sensitive ribbon tab with relevant controls.
