PDF Export Pen Colours

Hi,

First post on here, hello all.

I'm having difficulty changing the colour of dimensions on a drawing. 

I want the exported dimensions to be blue, 0,0,255.

I've created the config.pro file, also created pen_table.pnt  shown below:

! PEN TABLE

!(GEOMETRY, VOLUME) edges, volume
pen 1 color 0 0 0; thickness 0.05 cm;

!(LETTER)
pen 2 color 0 0 255; thickness 0.01 cm;

!(HIDDEN)
pen 3 color 0 0 0; thickness 0.01 cm;

!(HIGHLITE)
pen 4 color 0 0 0; thickness 0.01 cm;

! "Sheetmetal"
pen 5 color 0 0 0; thickness 0.01 cm;

!(SECTION)
pen 6 color 0 0 0; thickness 0.01 cm;

!(DIMMED)
pen 7 color 0 0 255; thickness 0.01 cm;

!(EDGE_HIGHLITE_COLOR) text
pen 8 color 0 0 0; thickness 0.01 cm;

I've set pen 2 to 0,0,255 for blue but when I export to PDF it opens in black.

I'm abit of a novice to the advanced side of this software but i'm getting there. I have searched around but nothing has worked.

Hope someone can help with this.

Cheers
