Objects in 2D aren't in the smae place in 3D

[Mickey]

I've created a cool 3d object.

When I place the object in the 2D drawing, with other objects near it, and then switch to 3D it is no where near the other 3D objects in the drawing.

What did I do wrong?

Try switching to the 3d view "top" before you place the object.

Or, switch to the 3d view of the object that you desire, do a convert "copy to lines", then select the 2d copy, and the 3d object and create a symbol. Then, when you place it in your 2d drawing, on a 2d view, you will see the 2d component of the symbol exactly where you want it.

The problem is that the overlay of the two different objects(the 2d and 3d versions of this object) do not line up correctly. Looking at just the object in question switch between 2d and 3d plan modes (0 and 5 in the number pad) I think you will find that your object jumps around between views. When you edit the object Copy a view of your 3d object and convert it to lines or polygons then edit the 2d part of the object and replace the 2d object with the new version using the paste in place option.
