scale problem again, hope to get help

[jinghui]

Hi guys!
I need some help on a scale problem. I did read many of the past posts, but still have problem. so... Well, i will describe what is going on.

I got a drawing with scale information 1:500. What I did it to scale it with a scale factor 0.002. The distance of 31490 then changes into 62,98. This is obvious wrong.

What should I do to change this into 1:! milimeters?

I am hoping for quick answers as i need to fix this very soon. Thank you!

Can u clarify a bit more.
1. R u doing this in papaercsapce? -(normally we do 1: 1 drawing in model space & set up the scale in viewport in paper sapce.)
2. the distance change from 31490 to 6,98 is appering in distance command or is it the dimension.
3. also check the units

OK... 31490 * .002 = 62.98 therefore what you have done is take your model from 1:1, which is what it should be, down to 1:500... not really what you want to do as a model should always be represented 1:1 usually using mm as the base unit.

To view/present/print this model you should go into paperspace & create a viewport (like a window onto the model) to the correct scale (eg. 1:500) & print this off (again at 1:1)... sounds a bit confusing but it's very logical once you get used to it.

For how to set up viewport in papersapce, refer to my reply yesturday in this thread

Hi,

1. No, I am in model. I got this drawing from our customer which is notified as 1:500 in the model space. I want to draw 1:1 in model space, so I guess i have to rescale the original drawing to 1:1 some how. What i did is to scale it with scale factor 0.002.
2. that is the dimension. sorry for the cofusion.
3. what do you mean by check the units?

P.S. Does this has anything to do with Measurement Units? As I checked it is 500 on measurement units.

if it's drawn in 1:500 in Model Space - shouldn't you just scale it UP with a factor of 500 to get it to 1:1?

[Hedgehog]

You shouldn't have scaled it by 0.002!... either undo your scale or re-scale the whole model up by 500 as Tiger says... then you'll be drawing at 1:1

Your mesurment unit appers to be ok(mm)

you should never scale in model space.

Ok so first thing u need to do this is scale it to make it 1:1 in model space in mm.
than u go to layout & set the viewport as mentioned in other thread.

to dimension in paper space, u need to specify relative scale factor under mesurement units under primary units in your dimension style. also tick apply to layout dim only. that way it iwll dimension correctly in model space also.

Hi again,

If i do scale it UP with 500, i.e 31490 *500= 15745000. This cant be right. As we are talking about a warehouse, which should be maybe 15 meters...( I dont have the real world measurement...) but i guess anyway it should not be 15745 meters.

Should you scale the original 1:500 by a factor of 0.5 to get to the units (m) you want?
