6. Digital Submission Compliancy
• CAD Standards Checker
• Attribute Checker*
o Complete attribute data
o Correct attribute data
• Topology Checker*
*Relative Checks
CAD Standards checkers
developed by
• FME reads submitted
AutoCAD Map 3D files
plus Excel files
containing validation
settings.
• Requirements :
1. GIS or AutoCAD, and
text or Excel outputs.
2. Easily customizable
settings for changing
needs.

14. Loading Data into CoK Database
• After drawing has passed all checkers the
data is ready to be exported from
AutoCAD and loaded into the GIS
database.
