How to convert Acad file to Ersi shape file (Ployline ZM)

[peterzhou]

I export a ployline from AutoCAD Map 3D to ESRI shape file, just it has X,Y values, but no Z, M values. Do you know how I can convert it to a shape file with X, Y, Z & M values, that is a Ployline ZM shape file?

Use the CAD to Geodatabase GP tool, fill in the mandatory parameters and click the Environments button.  In the Environment Settings, click the Z Values dropdown and under  the Output has Z Values, select Enable.  It "should" preserve the Z values.  Follow the same logic for M Values in the Environment Settings.  Good luck!
