Scaling

create a sub model and self ref the master model and attach it at a scale of  1/2"= 12 " or 1:24  ( ie 1"=24" ) or create a saved view of the master model and attach that as a ref  with 1:24 scale in the ref manager. . btw  what units is your design file in? We are metric here Australia so scaling is really easy....

How are you using your title block or sheet frame paper outline will also affect what steps to do?

Hi Lorys,

I have been trying the for weeks and cant get the sheet model to work can you help me with this?

Thankstest1customPreliminary_D_2D-backup.dgn

OK, let's begin with the fact that your 24" x 36" border is NOT 1:1 (as in 1" = 1"). That border is 1" = 1'-0". While we can work with that, it is an important distinction that introduces a factor of 12 into your calculations. This could be part of the issue.

Scaling from 1" = 1" to 1/2" = 1'-0" would introduce a scale factor of 1:24 (as in 1'-0" divided by 1/2" equals 24).

Since you are referencing this detail into two different borders at two different scales, you will not be able to use the annotation scale trick I use. That means you will have to manage the scaling manually, which still is not as hard as it sounds. Divide the right side of the scale equation by the left side of the equation, and set your scale to 1:number.

The default Bentley scales are based on details AND borders that are drawn 1:1, or 1" = 1". When you have a border file drawn at some other scale, you may need to do the calculations by hand.

Hello,

First of thanks for your help I am really a autodesk c3d user and setting this up in MicroStation V8i (SELECT series  3) - Version 08.11.09.578 is a little difficult so thanks for your help.

Ok, so if I understand correctly for the title block 24"x36" at a scale of 1/2"=1-0" I would need to have a scale factor of 24 and for the title block of 1/8"=1'-0" I would need a scale factor of 96.

Sorry I don't understand the part of the annotation the text so can you show me the steps for this for the 24"x36" and 11"x27" title block..

Thanks

Yes, you are right. You will scale your detail reference to 1:24 for your 1/2" = 1'-0" scale onto the 11"x17", and you will scale the same detail to 1:96 for your 1/8" = 1'-0" scale onto the 24"x36".

Annotation Scale is a model property that you can set in each and every model. This setting allows MicroStation to  manage text/dimension sizes, as well as detail scaling onto sheets. In this case, it may require a bit of back and forth, but once you get an understanding of how it works, it's pretty easy.

Let's start with your borders. As noted, these borders are not 1:1 (1" = 1"), they are 1" = 1'-0". That's fine, but we need to know that. In your border model, open the Models dialog, select the model with your border in it. Go to the Properties, and you will see "Annotation Scale". Set that to 1" = 1'-0". Now MicroStation knows what scale you will be plotting your border.

Go back to your detail drawing. We are going to use Rod's suggestion to create Drawing Models to better manage the fact that this is going to show up on several different sheets. Go to the Models dialog, and create a new "Drawing" model; we'll use this for your 1/2" scale detail. In that drawing model, attach your design at a scale of 1:1. Now (back to the Models dialog) set your annotation scale to 1/2" = 1'-0". Make sure that the Annotation Lock is set on in the Locks dialog (you can find that by typing "locks" into the little help-type window at the upper right of your screen). Now, all of your text and dimensions should come in at the proper size to show correctly on your border.

Go back to your border file. Attach your newly created Drawing model from your design drawing as a reference, and use the "interactive" option so that we can adjust some settings. The first is to make sure that you are attaching the drawing model, not the design model. Next, there is an option in the attachment settings dialog to select/set your reference scale. This will default to the annotation scale of the drawing model. This is where it can get a little confusing - you want to actually select the scale of your border model (in this case, 1" = 1'-0"). When you do that, you will see the scale factor (1:##) change. The last setting is that we are attaching this drawing model with Live Nesting to a depth of 1.

There are a bunch of other reference settings, but we will work with these at the moment.

Now your drawing is referenced onto your border. You can move it, rotate it - do what you need to get it properly located onto your border.

Steve,

As Mary has correctly noted, your titleblock is drawn in feet and you would save yourself a lot of hassle by scaling them down to their correct inches equivalent in your titleblock seed file(s). It doesn't matter if you draw your designs in feet, but your titleblock's really should match the actual paper size. Scaling titleblocks is something that used to be done long ago before the introductions of sheet models when some users preferred to reference their designs @ 1:1 so the titleblock had to be upscaled by the drawings scale-factor.

Is there any reason why they are drawn in Feet or is it just an unintended mistake?

Hi MaryB,

Here is what I got based on your explanation.
