Different scaled dimensions in different layouts Autocad 2009

[mcracken]

For example:
I have 2 or more view ports in layout (paper space) each has been Zoom XP to a different scale i.e 1:5 & 1:10

I am looking for a simple way to make both dimensions look the same size across different viewports.

I prefer to dimension in model space so I don’t want to go into the pros & cons of whether it is best to dimension in paper space as opposed to model space.

Below I have outlined what I have currently been doing to make the dimension thing work so as to avoid unnecessary responses that tell me what I am already doing, so to speak.

I create two dimension scales. For example I would call the first ‘Dim style 1:5’ & the second ‘Dim style 1:10’. For each of these dim styles under the Fit tab within the dimension style dialog box under “scale for dimension features” I would set the scale to 1. Also under the Text tab under “text appearance” I would multiply my text height i.e. 3 by the intended scale to be used in the layout viewport. So for 1:5 scale that would be 15 and 1:10 scale that would be 30.

I would also create two additional layers dedicated for use only with those dimensions, also named in a similar way to avoid confusion. When in paper space I would freeze the layer I didn’t want visible

I am also aware that you can change individual dimensions instead of making a specific dimension style as mentioned above. To do this you select the dimension string, double click and bring up its properties dialog box. You can change the dimension under ‘Fit’ which is called ‘Dim scale overall’. Here I would put in 15 or 30 as the respective overrides.

So even though I can get the result I want, it is a bit cumbersome and takes time. I have been researching this for a while for a better method and came across this extract from a forum site. It uses just a single dimension style which is applied to model space through the paper space viewport window.

*One Dimension style with "Scale for dimension features" set to "scale dimensions to layout (paperspace)".
*Associative dimensioning turned on.
*Dimension in model through paperspace (double click inside viewport).


It sounds great and just what I want but when implemented it just doesn’t work!!
What is it I am missing? Some hidden system variable??
Can someone enlighten me please.
