How to attach a reference with a 1:1 scale without using True Scale(particularly useful when attaching a reference with different workingunits and resolution then the active file with the desired result beingthe reference unit equaling the active unit).Product: MicroStation V8.1Version: 08.01.02.15Area: Reference
In the Reference Attachment Settings dialog box:- Turn off True Scale- Set the Scale (Master:Ref) to a ratio of 1:1 without actually settingit 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 andthe reference is scaled accordingly. This was the only way to attachreferences prior to V8. You can then change the Master:Ref Scalemanually to line up each unit in the reference to the master file.For example:Master File - 10000 per Survey FootReference File - 1000 per FootYou would like each foot in the reference to represent a survey foot inthe master file. Note that the recommended workflow would be to changethe working units in the reference to survey feet and scale the geometryaccordingly.In the above scenario, w hen the reference is attached without TrueScale on with a scale of 1:1, the reference will be attached with ascale of 1:10 (the difference in user defined resolution). Therefore, apoint placed at 1000,1000 in the reference will be located at 100,100 inthe master file. If you change the Scale in the reference dialog boxto 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 actuallysetting it to 1:1 (ie. 2:2, 3:3, 4:4, etc.) in the Reference AttachmentSettings dialog box, you are telling MicroStation to line up the UOR andthen change the scale to 1:1 automatically.
