Results
Electric Office (Source Data) Microstation DGN (Output Data)
How the Output Files are Used
Internally
Distributed to locate contractors
Additional versions with subsets of the data are distributed to GeoEdmonton
A partnership of companies and organizations for sharing spatial data
Problem
Dimensions are an unusual object type
No attribute data other than ID
Read into FME with dissimilar parts (Text, Leader Line, Right Arrow, Left Arrow)
Problem
Different dimensioning objects need to be styled (color, level) in the output
Solution in FME
Filter the text string based on prefix or suffix (ex. “P” from P 1.00)
Match each filtered string against each of the other dimensioning subtypes (Arrows, Leader Line components) using common ID numbers
Set the desired Microstation styling for each filtered type
Custom Transformers - Benefits
Organizes a workspace
Improves maintainability
Custom Transformers - Benefits
Allows you to quickly repeat a set of transformers, especially for data that cannot be merged
Custom Transformers - Benefits
Allows you to add documentation within the workspace
