Hello Everyone,

I have a 2d drawing & all of the lines  are suppose to be flat but when i look at the drawing in a 3d view there are lines at different elevations?...  I am wondering how I can fix this? other than moving lines manually?


Any help would be great!

Lee

Have you tried the flatten objects command in express tools - seems to work quite well, just take a while.

Cheers. Sean.

Use the command "flatten", from Express Tools.

If you haven't installed E.T. (you should) or are on LT, the following command sequence flattens most objects:

Command: MOVE

Select objects: Specify opposite corner: 5 found

Select objects:  Specify base point or displacement: 0,0,1e99
Specify second point of displacement or <use first point as displacement>:

Automatic save to C:\Documents and Settings\cab.EEI_AK\Local
Settings\Temp\ellipse test_1_1_9169.sv$ ...

Command: MOVE
Select objects: xx found
Select objects:<enter>
Specify base point or displacement: 0,0,1e99
Specify second point of displacement or <use first point as displacement>: <enter>
Command: <enter>
MOVE
Select objects: p
xx found
Select objects: <enter>
Specify base point or displacement: 0,0,-1e99
Specify second point of displacement or <use first point as displacement>: <enter>

I have tried the Flatten command, it appears to work - Thanks a bunch!


One question Carl, whats "1e99" mean in phrase 0,0,1e99 ?
I tried this and it did'nt want to work for me?

1e99 (One times 10 raised to the exponent of 99) is a ridiculously large number (for AutoCAD) that when objects are moved to this elevation, then in the negative z direction by same amount, AutoCAD loses track of initial elevation and z goes to 0.00.

and for selecting objects to be moved, you can use "ALL" on the command line rather than a window.

Here is a like to lsp file that will take care of what you're looking for.  I think that it worked better than the internal AutoCAD flatten:

Just curious - I must be missing something
why not just select all your lines, and in the property toolbar just type 0 for start Z and end Z. I just use it to do the reverse sometimes to elevate lines

I thought about that, but the Z coordinates box will not let me change value?  not sure why either?
