I'm getting what appears to me a measurement error in a complicated drawing. I've copied the components in question to another drawing and the error persists.

1. Draw a line 3'5"

2. Make a copy with the parallel tool and turn it into 3d plank the same length.

3. Check that the 3d item is the same length as the line from various views.

4. Use the dimension tool to show the length of both items. Use the ANSI standard.

Both show the correct dimension.

5. Change the dimension property to Stack Fraction.

The 3d shape now shows the length at 3'4" while the line remains at 3.5"

HUH???
