I have a brain cramp, can anyone tell me what the alternate scale factor for a 3/4"=1'-0" detail would be (I'm hindered by no paperspace). I have a detail that I want to keep the dims assoc. and is in modelspace along with titleblock and everything else. So, I've drawn it at 1=1, now I want to scale it up by a factor of 16. I know I need to work backwards to get the scale factor for the dims, but I'm crampin (14 hr day testerday).

Yes whdjr, that is it. But, unfortunately the problem is a bit more complicated than that. I'm actually trying to figure this out for a nice lady that works in the office here. She has a detail that she scaled up by 3. The drawing is 1/4=12 and the detail is 3/4=12. I think the alternate units for the dimstyle should be .333, correct. I'm in quite a pickle here, these are my dillemmas:
1. I have to get a drawing pkg out for an eng. that is leaving on a plane in the morning
2. I have 150 dwgs to plot
3. Some of these drawings have changes
4. This nice lady keeps asking me about this scale factor
5. My AutoCAD took a crap yesterday and needs to be re-installed
6. I'm typing this when I should be nose to the grindstone on the dwgs
7. I'm getting old and soft

Hmmm ... I'd probably prolong a solution / answer: "So I've got some experts working on it, <sniff>, what are ya doin' fer lunch?"
Sorry, it was my inner pig speaking.
:evil:

Yeah, I've got a few of those.

I'm not sure if this is what you want because I use a different Dimstyle with the Primary Units, Scale factor set to 1/3
but if you edit the individual dim properties and under primary Units, Dim Scale Linear, enter 1/3 not 0.3333

Never mind, I see Will had the correct answer, I was thinking 3 times not 16 times.
Should have read the post twice or maybe three times. Head in cloud today. :-o

I know I am going to sound like a nerd on this, but this was the way I figure out imperial scale factors.
Take the denominator and multiple by 12, and then divide it by the numerator.
Remember this from high school
X/Y=A/B
A = XB/Y
B = AY/X
X = AY/B
Y = XB/A
Therefore for ¾”=1’=0”
4x12/3 = 16
So 16 is your scale factor.
I have noticed thou you want to go from ¼”=1’-0” to ¾”=1’-0”.
Therefore
1/4=3/4
There using the equation above (X/Y=A/B), you wish to find X.
X/4=3/4
X= 4x3/4
X=3
But since your drawing is drawn 3x larger then the original detail the alternate units factor would be 1/3 or 0.3333333.
Which is what you had.
Now I could be all full ot it, but that is the way I would have done it. :mrgreen:

Works for me. I like you method. :-)

yeah...me too
I agree.
