Units: Inches

The issue is with Custom Backing Frame: 17 " x 11 " as a FINAL-BASIC

When generating an ISO from a smaller (shorter and less complex)steam header w/ drain line, the "Check" drawing appears correctly formatted to a system default drawing border.

FINAL-BASIC (See attached pics ...1 and ...2):
When attempting to set up a "FINAL-BASIC" type with a custom 17"x11", ANSI B, the system is reading in a backing sheet that is scaled much larger than the isometric generated.

QUESTION: By default does ISOGEN automatically use full-size backing sheets or does it scale inch-based, back sheets such as a full scale 17"x11", ANSI B sheet based on a metric conversion factor?

The issue could be the units in your backing sheet. Try to set them to decimal and see if that helps

Will do, Matt. No doubt, a rookie mistake.
