You can select the value of a point on the system level, by editing the GlobalConfig and setting the attribute BigPoints to False or to True.
This is one of the first steps of the GN4 configuration, and definitively to be carried out BEFORE you start to build styles and pages.
There are two choices:
•BigPoints = False (default)
The point size is 1/72,27 inch (so called "Tex point", equal to 0.3514598035 mm)
•BigPoints = True
The point size is 1/72 inch (so called Postscript point or big point, equal to 0.3527777778 mm).
To see if your system uses big points or not, execute this line from the Script Editor:
msgbox (DataConnection.Instance.ClientLogin.GlobalConfig.bigpoints)
If it displays True, your system is using big points. Otherwise, it will display false.
Note
After changing this value in GlobalConfig, you need to reset the IIS and restart GN4 applications.
Example
Let's suppose you've enabled big points by setting BigPoints to True. Run Fred4. Create a horizontal rule, with 1pt weight. For the measurement display in the Measurement palette, select m. The weight of your 1pt rule will correspond to 1004m.
Now, disable big points, reset IIS and restart Fred4. Create a new horizontal rule. 1pt would correspond to 1000m.
Have in mind that the 'm' unit is independent of the BigPoints setting, and it is always 1/72270 inch, or 0.003514598035 mm.
Note
Under certain circumstances, especially when using big points, the rounding error in Fred4 may cause the text frame height to miss 1 or 2mpts, and therefore to drop out the last line of text, although it looks like there's enough space.
The solution is to slightly reduce the starting offset of grid in the format. For example, if the grid value is 9.8pt, put it as 9.799 or 9.798.
The visual impact is null, as it's not possible to notice a 2mpt shift, and it would be enough for the last line of text to fit the frame also with the wildest rounding.
