Topic: Move everything to #,#,0?

[craigr]

I would like to have a macro to move everything to zero on the Z axis.

1. Is there an problem with doing this?

2. I don't know how to do this. I know the 'draworder' thing, but as I understand it, that isn't really moving anything. I want to select everything in the dwg at once, and move it to zero on the z axis.

Do any of you already have a macro to do this?

Thanks in advance,
craigr

Hi Craig,

The problem with this method is that each type of object is stored differently.
In other words to move a line you must set the Z coordinate to zero for both the start and end point of the line. A circle, by it's center point, text by it's insertion point, etc...
I have a VBA program for this that works on lines, circles, arcs, text and mtext, that you are welcome to have. Just send me a PM if you are interested.

Just send me a PM if you are interested.

Thanks for the offer, but alas, I am using LT 

LT doesn't use VBA or Lisps

I guess you don't have "flatten" eh?

[craigr]

I guess you don't have "flatten" eh?

'unknown command' - or were you joking?

Really, that is exactly what I want to do to the dwg.

nah, it's a real command for full autocad... but I think it is still an "express tools" command which means it's still just a lsp addin.  I don't see why they wouldn't add Flatten to LT... the whole purpose of the command is "Convert objects to 2d" which I would say would be most used BY LT users....

have you tried using the properties window and changing all the x and y values?

(might work for a few... not everything, but some)

Can you use qselect filtering?
filter for all lines...set start and end point z-coords
filter for all circles...set z-coord for centers,
etc...

The macro works great.

Thanks for the link.

The macro mentions '1e99' as the value of the 'z' axis. Does anyone here know what '1e99' is?

The natural logarithm, formerly known as the hyperbolic logarithm, is the logarithm to the base e, where e is a certain constant approximately equal to 2.718281828459. The natural logarithm can be defined for all positive real numbers x as the area under the curve y = 1/t from 1 to x....

So e raised to the 99th power?

[Gliderider]

1 to the 99th power. (1 exponent 99). From what I understand, acad can't work with such a large number, so it considers it 0. (I think)

Oops... 1 x 10 to the 99th power. 1 to the 99th power = 1

[Tramber]

Beleive it or not, the 1e99 (in Z) movement (and then back -1e99) is the official method from Autodesk to be used in LT.

This technic was created by Randy Richardson from Tee Square Graphics.

Holy Cow!!!

You folks are great! Is there anything you CAN'T answer?

Thanks for all of the responses,

1e99 is scientific notation.  It means 1 x 10^99.
