I'm a Microstation user switching to C3D, in Ustn you can 'warp'(move,rotate,scale) a raster image using a minimum 3 points in the cad file, is there a similar function in ACAD/C3D?

Use the 'align' command.  Should get you close to what you need.

That's the ticket. Powerful command. If any elevations or z values are different, the image could get warped.

yes, make sure your 'osnapz' option is set to '1' if you'll be snapping to anything that could have an elevation.

Thanks, it worked.

While searching I found a command called 'adersheet' it says it rubersheets? Tried  it keeps twisting image, maybe the osnapz.

If you work with Survey points in C3D the 'osnapz' command will be a highly utilized setting.  If it's set to '0' and you do a 'distance' command it will return slope distances all the time.  I've been meaning to create a toggle shortcut for it like F8 for ortho but haven't done it yet.

There is a lisp routine than defaults the program to zero elevation every time you start it. Then, if you want to draw 3D lines, you can turn ot off as needed.....
