AutoCAD Map 3D 2009 is the only one of the product in Autodesk, it has been certified by Citrix XenApp softwares. So it can be claimed that it supports multi-platform (e.g. Windows, Linux & OS X). I have tested and captured some screen shots as following:

Testing environment :

Today the user asks how to create or delete feature data. I think this is very simple task. Just use copy/ remove command or create new feature from geometry.... But she said it really doesn't work!!!

Recently I requested by an end user to test how to good manage file conversion from sdf to shp. They have produced a lot of sdf file in their project. They concern how to add new field to existing feature data and how to convert it to shapefile. Basically I uses the follow step(1-mapimport the sdf with proper object data attribute -> 2-mapexport to shp).

Autodesk is moving beyond drawing-based CAD. On May 7, 2008, Autodesk, Inc. announced that it has acquired substantially all of the assets of REALVIZ S.A., a developer of image-based content creation software.
