Best Practices - LineStyle Scaling with References

David Renaud
Offline

OK, I have a plan view design file. I am referencing it into a sheet model file for some annotation and plotting. I am referencing the same file into the sheet to detail certain areas.

The main design is both drawn at 1:40, and inserted to the sheet at 1"=40' (MU/SU are Ft/In). Our entire organization works at 1:40 - this practice started years before before I was around. But, sheets have to be set to 1"=40' or the borders are 1/12th too small.

The details are referenced in at 1"=20' (Master:Ref is 2:1).

The lines in question are custom linetypes - a dash with a piece of text. All the linestyle scales on the elements in the design file are 1.0000.

I've played with the reference file global linestyle scaling settings on the detail to get the scaling correct, but nothing seems to work. The scaling appears either twice the size I want it at (details are blown up by two), or something so far off that the lines appear solid. The only way I can get it to work  is by setting the drawing scale in the sheet (Master) dgn at 1"=2', have the main view (1"=40') get the linestyle scales from the reference, and the detail references get it from the master.

However, changing the drawing scale also changes the scale of the sheet border I am using in each sheet model. I want the borders in there to make plotting as foolproof as possible. And my active linestyle scale starts wacking out, too. If I set the drawing scale to 1"=40' the linestyle scale goes to 1"=480.

This can't be that hard to do, but I'm totally lost at this point. Maybe I should set the units to MU:SU to Inches (1"=1") since the sheet is an 11x17 inch, then reference the files in at either 1:1 (plan) or 2:1 (detail)?

    I tried this http://communities.bentley.com/products/microstation/f/273/t/74166, but I get the message: "Cannot modify attachment level attribute." The reference files settings for the details are set to Always allow overrides. So it's a workaround that doesn't work. I'm ready to smash my computer. The competition makes this so easy that the two hours I've wasted trying to do something as simple as having lines scale correctly would be laughable if I didn't have so much to get done.

    After reading this thread an your comment I feel your frustration with this. However, I believe I have found a solution. If you go to your workspace configuration and choose the "reference" category and then choose the "default attachment settings" and enter in globaLSScale=Reference. You should have your problem solved.

    It take the linetype scale of your reference and applies it to your drawing, otherwise the linetype scale of your reference will always be different from your drawing and you'll be constantly running in circles.

    As this is Title Best practices the best practice is to get scales set properly implement from the start. I continue to see this scale issue over and over again. Just had to deal with it again last week. Implementing Annotation and other scale relate element will result in nothing but frustration for anybody who doesn't have their scales set properly from the start. Almost every time I get called in to sort out an annotation or line scale issue its because they don't have the scales set right to start with.

    Its best to bite the bullet up front and reset your borders, line styles and text styles to the proper scale.

    I totally agree with DavidG

    And because I work in Metric thank God, we saw  the light back in the late 60's, and your  imperial sizes and scales have  given me a headache just trying to follow your thread.

    Go back to your  model draw in 1:1  true scale, set your text size and styles to 1:1  and annotation scale 1

    now use the sheet mode and ref attachment a drawing sheet and set it  to 1:1 

    Attach your ref !:40

    Alternatively Scale up your sheet 40x real world at attach your ref file 1:1 and  tell printer to scale it to the  paper size name  this will do the 1:40 reduction for you..

    Just to clarify.

    A Civil Drawing using  1"=40' has a scale ratio of 1:480  

    40 x 12" = 480"  so 1"=40' is 1"=480" so 1:480 is the scale ratio.

    Architectural  1/4" = 1' is a scale ratio of 1:48

    1/4" = 1' is the same as 1" = 4'  4x12" = 48  so we get  1" = 48" which is a scale ratio of 1:48
