I converted my shapefile to autocad. How can I see my fields in autocad.
AutoCAD is a vector drafting software so it doesn't have attributes in the traditional GIS sense like ArcGIS or other GIS's do. Its attributes are meant for the vector (line) parameters such as colour, line thickness, etc. You can add CAD fields to your shapefile and populate those fields with attributes prior to exporting to CAD which will control the visual attributes of those vectors.
It is not possible with plain AutoCAD without additional coding, since AutoCAD does not provide GIS tools out of the box. I suggest you try AutoCAD Map 3D or AutoCAD Civil 3D applications which do provide rich set if GIS tools to create, edit and view SHP files and related fields (including other GIS-like data sources such as MySQL, SQL Server Spatial, PostGIS, Oracle Spatial, etc.).
