This should really be in thedetailing forum and there are loads of bloggs on it there to help with dims style text style and annotation scale.. but in the spirit of answering you here ishow I do things and I think its the simplest
and consistant way if you set up a few things and use them all the time you'll imporove you productity alot..
Draw 1:1 in feet so draw object 8ft long and measures 8 ft long
scale up your drawing sheet X96 times, not your active work or model, then when you print it will be to a paper size 1:96 or 1/8" = 1 '
Let the printer scale the drawing down to the paper... The drawing sheet can be a reference file or a cell or sheet model.
If you tell cad the drawing scale and use annotation scale for text and dims you wont need to calculate the text height to draw in so it prints scaled down correctly..
In in australia we use metric so forgive me I'll speak metric.
My standards allow for the following text heights in mm on paper 1.8, 2.5, 3.5, so I set up text styles with the annotation scale attribute turned on ...
I attach my drawing sheet scaled up to suit a standard scale lets say 1000x fits my needs and covers the right amount of space...so when I print it will need to reduce down to fit the real paper size 1/1000 right?
Now there is from the pull down menu
settings> >drawing scale
set that to what you need to use so as to allow in my case 1:1000 with the annotation scale set to on
Now when I dimension or annotate text I chose a text style for the height with annotation scale set on so if I want 2.5 text on the paper finished print size then I choose text style 2.5 and the annotation scale will automatically do the multiplication or division required rather than me use a calculator or Leroy tables... now for metric its too easy but for you imperial units guys this is a God send..
I set my Dimension style without text so it uses the active selected text style but I have set some parameters in the dimstyle like how I want arrow heads etc...
You can set the text styles up once either in your seed file or in a filenamedgn.lib file which is still a dgn but saved with the .lib and stored in a library folder and microstation is told where to look for libraries..
These will become your company drawing standards and when set properly will be automatically available when you start drawing simply by telling microstation what the drawing scale should be with the annotation scale activated...and choosing from the pull downs in text style box what predefined text style size you want to use...
Why bother apart from calculation text simplicity.. ?
Say you just finished you first draft at say 1:200 scale and the client or boss wants more details added and there is not enough room or they want it on a different sheet size now without annotation scale big problem...
with annotation scale no problem .. change the sheet size , change the drawing scale and bang! instantly all text and dims have automatically altered to suit the new requirements by them selves!!!!!!!!! ...
My first drafting boss 20 years ago once told me if you cannot handle change then your in the wrong job ( ie drafting)..
You need to do some study or some training I'd recommend a great book on all this if I may ..by
Keith Little " the survivors guide to v8 " has all this stuff and more ..a little bit dated now as it doesnt cover sheet organiser and geographic tools, but an excellent resource but you can learn that more advance stuff later from other supplemental booklets from Envision Cad ( also great and available as ebooks to save on costs).
I hope this has been instructive and gets you out of your predicament ..
Good luck and feel free to contact me offline via email messages if you need more detailed help or explanation.....
