Currently, some of their section drawings show the firebox opening to the left side of the drawing, and others show the the firebox opening to the right side of the drawing. I believe they should be consistent and would like to know if their is a standard or widely accepted convention for how to present a fireplace section. The same question could be applied to window sections, cabinet sections, etc. Are the terms "first angle projection" and "third angle projection" widely understood in the architecture business? Which is used? Does National CAD Standards define this? Corps of Engineers? Other standards setting organization? Michael Chusid, RA FCSI CCS www.chusid.com www.buildingproduct.guru J.

I would use terms like "plan," "elevation," "section," and "detail." You are correct in suggesting that orientation be consistent extended from the overall section to the detail section.

I know of instances where mis-interpretations have occurred.

We all need to respond to our audience. Terms like plan, section, elevation, isometric and axonometric are known terms to those in the building community. I would keep it there.
