Flatten a DWG

[Marcus.Isacsson]

Hi fellas!

I wonder if anyone has tips for flattening a DWG. I've been trying "Flatten" included in express tools but it doesn't seem to quite do the job. Or do you have to prepare the file with other commands before flattening?
(Circles, hatches, height curves, lines and so on)

Thanks in advance!

This seems like an AutoCAD question, not an ACA one. To create 2d views of architectural objects, use either the display system  for orthographic views or an elevation or section tool for 2d elevations or sections and use the callout tool for plan views.

Flatten only works on 3d solids.

The other consultants (Revit users) wants the DWG to be completely flat. All lines etc. at z-value 0,0 for everything.

Use callouts to create the views or use exporttoautocad. If you use exporttoautocad, be sure the view you're exporting is an orthographic one, not an isometric one.

Anything left that has a z coordinate other than 0, can be fixed by using 2 move commands.  Move everthing by a vector of 0,0,1e99. Then move everthing back from 0,0,1e99 to 0,0,0. Make sure dynmode is off or use WCS prefixes for coordinate entry.

Thanks for helping out. But I found a LISP that did wonders, Superflatten 2.0c (by Joe Burke)
