Flatten Command

[ndavis0425]

I'm using an old Civil line drawing as an underlay. I'd like to flatten the lines which are at many different z locations. My autoCAd does not recognize the "flatten" coomand. What can I do?

The easiest way it simply to lock the 'Z'
coordinate in the new drawing. Click the Icon in the lower right corner that
looks like two bricks with a Z superimposed upon them. When it is blue it is
locked. The Elevation indicator immediately to the left of that icon indicates
the Z elevation is current when locked.

style="PADDING-RIGHT: 0px; PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #000000 2px solid; MARGIN-RIGHT: 0px">

Thank you.

In current drawings I have a lisp file that I load in order to flatten. I tried to upload it as a lisp file but it wouldn't let me. So save it and change the .doc to .lsp. Then just type in the command line: appload, then select the flatten.lsp file, close out the command box and then type: flatten in the command line and select all, it won't flatten your 3D objects so you're safe with that.

The OTB express tool doesn't flatten the way I recall it from years past - it now moves line work around giving undesirable results.

Anyone have a better solution?

try using the following command,

CHANGE
select all
properties
elev
0

this will change the elevation or Z coordinate to 0 for all objects. This moves all abjects to 0, however lines that have differing start and end Z coordinates need to be amended through the properties panel. This doesn't flattens 3dpolys or splines though.

Hope this helps

alternatively, if you are solely dealing with lines and no curves you could used the CREATEHLR command in plan. This will create a 2d block of the view.

Kevin, thanks for the CREATEHLR command worked like flatten did before the days of dynamic ucs.

Oddly enough it isn't found in help...

Greatly appreciated!
