Merging .DWG files in AutoCAD

I have two drawings in AutoCAD (2004LT)
One is a complete plant outdoors, the other is the inside of one of the buildings.
I would like to merge both drawings in one, so that the inside of that building is present on the other drawing.
What is the easiest way to proceed ?

Thanks,
Chris.

scaling can get tricky, especially if they are not drawn full scale. I'll try but I may confuse you, and probably my self too ;)

when you mean another scaling do you mean one is drawn with architectural/engineering units(1' = 12 drawing units) and the other is drawn with decimal/fraction units(1' = 1 drawing unit)?

Check the dwg units of both dwgs to make sure: format->units.

If thats the case and you are trying to bring in a arch/eng based block into a dec/fract based dwg scale your block down by .0833 (1 / 12) if going the other way scale it up by 12 (12 / 1). Basically what you have to do is divide the scale of the dwg you are going to by the scale of the dwg you are inserting, and use that number to scale the block by.

Now, if somebody did something like draw it to where 1 drawing unit = 300 scaled units(like we used to do on paper), imho you are better off scaling the whole thing up to 300 that will give you something better to work with.

I hope that wasnt too confusing, I can do it alot better than I can explain it.

There is another way that works good for me using the scale command on a block already inserted. Look at the scale command in the help file and read about the "reference" option. You can scale a line in a block up to what you want it to be.

What are the scales you are working with?

You could xref one into the other, or xref them both in a seperate drawing. INSERT->XREF MANAGER
If you just want to have everything in one drawing you could use the insert command to insert one into the other as a block.
I would probably just select everything that I wanted from one drawing, right click, select copy with base point, then right click in other drawing, select paste as block.
Make sure you have a common point that the drawings share, it makes it easier to insert. Then explode the inserted block when you get it where you want it.
hope that helps

Thanks for the answer norrin radd... But the building I'd like to insert has another scaling that the drawing of the plant. Any idea how I can get the scaling changed..?

Thanks,

Chris.

Hi,

It works thanks. I used the scale command on the drawing I pasted... Also Xand Y axis were switched...

Thanks a lot for the help norrin radd...

Hey,
Thats great, thats probably the easiest way to do it. I use that scale->reference thing a good bit.
