Important Notes when Referencing:
• Be aware that if the Line Styles were placed in the basemap using a Scale factor other
than a Scale of 1. The referenced line styles are scaled by the Model Properties Line
Style Scale set in the new design file and will appear out of scale.
• If the survey data was mapped (visualized) in the basemap for a specific scale, such as
20, set the option “Global Line Style Scale” to Reference in the Reference
Attachment Settings dialog box to match the Annotation Scale value set in the original
reference file.
• If the Model Annotation Scale is already set in the design file and the Model Annotation
Scale is set in the Reference at 1:1, the Detail Scale in the Reference Attachment
Settings dialog box displays the Model Annotation Scale and the Scale (Master:Ref)
displays a 1:1 scale like shown below:
• Be aware if the Model Annotation Scale is already set in the design file and the Model
Annotation Scale is set in the Reference other than 1:1, the Detail Scale in the
Reference Attachment Settings dialog box displays the Reference’s Model Annotation
Scale and the Scale (Master:Ref) is then calculated from the referenced model's
annotation scale and the active model's annotation scale.
For example if the Reference file has a Model Annotation Scale set at 1:20 and the
design file has a Model Annotation Scale set at 1:50 the Detail Scale displays the
Reference’s Model Annotation Scale (1:20) and the Scale (Master:Ref) is calculated
2.5:1 as shown below:
To avoid the Reference from scaling in the design file like shown in the example
above make sure the Scale (Master:Ref) is set to 1:1. If the Scale (Master:Ref) is not
set at 1:1 you will need to change it. Once you have set the Scale to 1:1 the Detail
Scale will then read the design file’s Model Annotation Scale that was set like shown
below:
