Geometry Exchange – Open-for-Comment

Post note: This post is for a technical audience.

The PCA Geometry Special Interest Group (SIG) team has released draft documents that provide the details of the ISO 15926 Part 7 Templates to be used for Geometry exchange. The initial focus is on 2D geometry. The Geometry SIG team is seeking comment from the broader ISO 15926 community, and implementers who are interested in Geometry Reference Data.

The two documents to be reviewed are Details of the ISO 15926 templates used for Geometry exchange and Geometry Template Signatures in a spreadsheet format.

The Geometry SIG is requesting timely comment on these documents with a deadline of December 5, 2012.

To comment on these documents please go here:  Geometry SIG discussion forum at

The Geometry SIG team continues to collaborate with the IIP, Proteus, and the JORD teams to finalize the templates required for the complete P&ID representation and will move on to 3D geometry for process plants in the next phase.

Finally, the Geometry SIG team welcomes more participation, please contact Manoj Dharwadkar (, Geometry SIG Chair, if you are interested.
