Convert AutoCAD 3D to just 2D - Flatten and Flathot doesnt work

[Morne]

OK So even after exploding the objects, the flatten and flatshot commandf still dosnt do anything, There was a command I use to use way back on version 2000, but havent used it in such a long time that I cant remember what it is now

if you have 3d objects from Autocad Architectural desktop (such as wall, doors, roof, etc) you do need to go to plan view and export in dwg, all the 3d objects will be flat lines, if you have solids or lines flatten should work.

yes thats what I'm going to do now (only have AutoCAD) installing demo of AutoCAD Architecture now to do just that

[Morne]

but autodesk should really have some mechanism to handle these situations. Sometimes people sending you the files are reluctant to follow "a certain procedure" to export a file just for your needs.
And sometimes they already gone out of business and you can't get hold of them etc.

If you export it as AutoCAD LT should be in 2d......if you want to explote the geometry I think it has to be 3 times.(ADT uses multiview objects)
I don't remember if you need to install "Object enabler" to handle ADT geometry inside regular Autocad.

if you export to autocadLT its still the same as just autocad (original from autocad). LT can still read 3D even though you can't draw in 3D ie extrude stuff.

The demo of Autocad Architecture (formerly ADT) worked as in I just open the file and export to AutoCAD. that auto explodes all AEC and flattens it like expected.
Then just re-open the new file in standard AutoCAD
