Problem
How to attach a reference with a 1:1 scale without using True Scale (particularly useful when attaching a reference with different working units and resolution then the active file with the desired result being the reference unit equaling the active unit).
Solution
In the Reference Attachment Settings dialog box:
- Turn off True Scale
- Set the Scale (Master:Ref) to a ratio of 1:1 without actually setting it to 1:1 (ie. 2:2, 3:3, 4:4, etc.)
The default ratio is 1:1. When attached with 1:1 without True Scale on, the attachments is lined up with the system's units of resolution and the reference is scaled accordingly. This was the only way to attach references prior to V8. You can then change the Master:Ref Scale manually to line up each unit in the reference to the master file.
For example:
Master File - 10000 per Survey Foot
Reference File - 1000 per Foot
You would like each foot in the reference to represent a survey foot in the master file. Note that the recommended workflow would be to change the working units in the reference to survey feet and scale the geometry accordingly.
In the above scenario, w hen the reference is attached without True Scale on with a scale of 1:1, the reference will be attached with a scale of 1:10 (the difference in user defined resolution). Therefore, a point placed at 1000,1000 in the reference will be located at 100,100 in the master file. If you change the Scale in the reference dialog box to 1:1 that point will be located at the desired position, 1000 ,1000.
By setting the Scale (Master:Ref) to a ratio of 1:1 without actually setting it to 1:1 (ie. 2:2, 3:3, 4:4, etc.) in the Reference Attachment Settings dialog box, you are telling MicroStation to line up the UOR and then change the scale to 1:1 automatically.
