AutoCAD macro to draw 3D objects

I want to use AutoCAD to generate a 3D model which is composed of many basic 3D geometries such as sphere, cube, etc. I have the dimensions and the origin and orientation of the local coordinate system of the basic geometries. The data are stored in an Excel file. Each row of the excel data corresponds to one geometry and the columns are for dimensions, origin coordinates, orientations and desired layer info. The data format is defined for each type of geometry. Those geometries can be easily generated in AutoCAD using commands. I wanted to use AutoLisp or VBA or some other macro tool for AutoCAD to auto this process so that when the data is changed, I just need to run the macro to read the data and regenerate the AutoCAD 3D model.
