CAD Data Validation using FME


Published on

Auditing and validating CAD drawings against an established standard is a critical part of a robust CAD data management protocol. Oftentimes this consists of one or more drafters/checkers performing drawing audits from within AutoCAD using out of the box standards checking tools. This process can be time consuming and costly especially when a large number of drawings must be processed within a short time period. Several third-party applications exist to assist with this process but most require an extensive setup and an external database. Colonial Pipeline Company has developed an automated toolset using FME Workbench that checks incoming CAD drawings against its Drafting Standard and provides a detailed log of errors and compliance issues discovered within the drawing files. This toolset drastically reduces the time needed to audit drawings and utilizes software already licensed and used by the GIS department. This presentation will focus on the business drivers for the development of the tool; an overview of the tool; a demonstration; known limitations; and a discussion of next steps and future possibilities including FME Server, cloud deployment, and industry collaboration.
