DWG Files Not Scale Says Client
-
-
That didn't work, it created a top view of the whole model?
-
How about this, I Edited all the dimensions but kept them at cm, then I changed the Model Units back to inches and exported a 2d dwg?
I measure these with P Con and looks good to me?
-
And LayOut can't do it?

Joe, that's like saying you own one of these but the only feature you use is the slot mortiser.
-

but I'm trying it right now!
in Layout is it a dwg and can he measure the endpoints Etc?
-
yeah you're right but that's all I've ever needed out of SUp just the basic tools.

You can export a DWG from LayOut. LayOut makes it easier to display the views of your model and its parts. You can add dimensions in LO if needed and generate PDFs with properly scaled views.

No, I mean to use the LayOut dwg export. Actually I don't know. I use it in some limited fashion in Imperial. I get weird results tryin it in cm. If you need dwg files, I guess SU isn't the way.

I'd rather find out what my dwg export issue is fellas.

From what I've read in this thread, you've been told what you export issue is.

I must have missed it Dave, does this dwg resolve it? All the measurements read correct for me?
-
If the solution is using Layout, can someone point me to a Tut showing how to set it up for drawings like these? I tried last night but only got as far as the initial paper sizes, and none seemed to fit my drawing?

To me that comes out of scale. Off by some factor less than 3. I guess it's what TIG said. Scale by 2.54.
-
How do I scale the whole model, so I can export this dwg correctly?
I asked if he could scale on his end, and he said-
"This scale (1/2,54) does not exist, it is a scale of your drawing relative to the filling to the size of your screen.... or else it is: 1/1;1/2;1/5;1/5;1/10;1/20;1/25;1/50;1/100;1/150 Etc.............But that doesn't change anything! whatever the chosen scale the measurements do not change since they are taken on the drawing at 1/1 scale which is the dimension of creation of your drawing. The scale is only used for viewing or printing."
-
You have to scale in the CAD version (not in terms of "drawing scale" but in terms of selecting everything and making it larger.)
I wish I understood what is happening.
Here's what. If I open in PowerCADD and just open it as feet and inches. It's OK if, after I make the file I THEN change the units to cm.
If I set the units as cm at import, the scale is off 2.54. then enlarging the drawing will give the correct scaling in cm.
Try this one that I resaved in cm.
-
I wish I understood what is happening too, but you're really trying to figure it out Pb!
I'l send what you wrote to him, see if he can make it work but he's probably gone until next Tuesday. Thanks so far for your effort man!
-
Folks I need to get this resolved, why aren't these dwg to scale in CM?
Is this the answer from PB?
'If I open in PowerCADD and just open it as feet and inches. It's OK if, after I make the file I THEN change the units to cm.If I set the units as cm at import, the scale is off 2.54. then enlarging the drawing will give the correct scaling in cm.'

Joe,
Your files straight out of Sketchup are to scale, but as TIG pointed out, when you export out of Sketchup at 2D you cannot export in Metric units. (SU native Imperial units remain intact)@joe wood said:

Joe,
Yes, that sounds like exactly the right answer, but.....for PowerCadd....we simply cannot be certain it will behave the same in the CAD software your client is using.
However, what we can determine from the image you provided is:
As TIG stated the SU native Imperial units will remain intact if .dwg is exported as 2D from SU and the text I added in the image above was an attempt to illustrate just that.
Note: your SU dimensions shown typically are no longer "active" when imported to other CAD software and are simply lines with the text sometimes preserved.So, although you "see" the dimension 319.98 it is not actually representative of the imported .dwg dimension. And the math provided very closely proves this out.
So, in short, I would attempt to explain to your client that a conversion on his end from imperial to metric will be necessary.
The top dimension your client shows in the image 12597.7
cmx 2.54 = 31998.158(mm) divide by 100 = 319.981 or round to 319.98cm -
The magic command in AutoCAD LT -DWGUNITS will convert the drawing unit and scale your model appropriately, like the one I attached.
