XS_DRAWING_GRID_LABEL_FRAME_LINE_WIDTH_FACTOR
Category in Advanced options dialog: Drawing Properties
Use this advanced option to change the thickness of the grid label frame in drawings. You may want to emphasize the grid label frames so that they are shown with a thicker line than the rest of the grid.
Example
XS_DRAWING_GRID_LABEL_FRAME_LINE_WIDTH_FACTOR=1
Note:
Each color has a certain line thickness. The thickness of the grid label frame on the printed black-and-white drawings depends on the color that has been defined for the grid label in the grid properties and on the value of this advanced option.
This advanced option is model specific and the setting is saved in the options database.
