I noticed that the lineweight for centerlines is really thin. Whats the procedure to increase that thickness? I got the setting to use pen tables with PDF creation and I got a pen table. Maybe its just one of those pens that needs to be a bit thicker?
Traditional drafting standards would dictate that your centerlines would be the thinnest lines on the sheet, with hidden lines next, object lines after that and section lines as the thickest. So, what you're getting is proper, center lines should be very thin.
That said, most pen table files that I have seen are commented, try opening it in notepad or another text editor. Pen 2 controls center lines among other things. I've attached our plotter table file for your reference, which we use for PDFs too.
I remember back in the day of pencil on velum, I had 4 mechanical pencils for the 4 line weights I needed to make - 0.3mm, 0.5mm, 0.7mm and 0.9mm. Sometimes I miss those days. Not often, but sometimes. :-D
because when you print to gray scale, the single control for dimensions/text and centerlines has an automatic differentiation between the three that cannot be altered.
So the text and dimensions are always darker than the centerlines for gray scale or thicker in the case of black and white. Setting the color to black, makes the centerline more visible than when its printed as gray (as is by default when not using the pnt file.)
