Many AutoCAD commands are equivalent to commands in Autodesk Inventor. Autodesk Inventor has additional commands that have no equivalent in AutoCAD. In AutoCAD, you create 2D geometries to the required dimensions. In Autodesk Inventor, the dimensions drive the geometry parametrically.
Several commands in Autodesk Inventor combine the functionality of multiple single commands in AutoCAD. The General Dimension command creates a linear dimension when you select one or two elements, a diameter dimension when you select a circle, and a radius dimension when you select an arc. This command replaces several singlepurpose AutoCAD commands.
This table shows AutoCAD Dimension commands and the corresponding Autodesk Inventor Dimension commands in 2D Sketch environment.
