3D To 2D

Please help!! Is it possible to change a 3D point to a 2D point in Cad?

Yes, command FLATTEN

And please don't double-post.

Sorry If I double posted, Its my first time using this site! I have read you can use flatten on the express options, however I have Autocad 2006 and do not have this express option. Is there any other way?

if you have AutoCAD full, then you have payed for Express Tools - find the installation CD and install them.

Depending on what you really mean with "make 3D 2D" and what objects you have, you make highlight them and use the command CHANGE to change properties on the objects (or bring up the Properties palette)

To expand upon Tiger's post above re: Change.

Command: Change

Select objects: pick the object you wish to change.

Select objects:

Specify change point or [Properties]: type P for Properties

Enter property to change

[Color/Elev/LAyer/LType/ltScale/LWeight/Thickness/Material/Annotative]: type E for elevation

Specify new elevation : In this example the object's elevation is 1.00. You want to specify the new elevation as 0.00

The command will repeat the prompt Enter property to change... Hit enter to exit.

Done.
