Just posting a script Michael did me the other day.
If you use this script or both of them it allows you to zoom into the screen and get dimension sizes looking great

I use these scripts in conjunction with settings > “scaling dimensions by screen size”


Increase font size:

script: /* Increase dim font size */ var dims = moi.geometryDatabase.getObjects().getAnnotations(); for ( var i = 0; i < dims.length; ++i ) { var dim = dims.item(i); if ( dim.fontName == '' ) { dim.fontName = moi.ui.fontName; dim.fontPtSize = moi.ui.fontSize; } dim.fontPtSize += 3.0; }

Decrease font size:

script: /* Decrease dim font size */ var dims = moi.geometryDatabase.getObjects().getAnnotations(); for ( var i = 0; i < dims.length; ++i ) { var dim = dims.item(i); if ( dim.fontName == '' ) { dim.fontName = moi.ui.fontName; dim.fontPtSize = moi.ui.fontSize; } dim.fontPtSize -= 3.0; if ( dim.fontPtSize < 1.0 ) { dim.fontPtSize = 1.0; } }
