how to make the drawing bigger when converting to pdf

Me too you got the drawing ?

Yes, I do. So you want to print this out on a A4 size piece of paper?

This is what I would do assuming you want to print directly from model space.

I would first draw a 1189x841 rectangle. I would center this around the objects in your drawing. Then I would start the Plot command and make all the necessary inputs in the dialog box depending on whether you are plotting directly to paper or creating a PDF.

I sent you an email with a revised version of your drawing attached and two images of screen shots I took of my plot settings for printing to paper and for creating a PDF. Now I have to step away from my desk for a while. I'll check back later.

Thanks so much guys , you help is much appreciated

I got the solution , special thanks for ReMark

I really don't think he learned anything from this maybe we should call it CAD-R-US. Glad he got what he needed tho.

The problem was solved to the OP's satisfaction via email and private messages. I think he'll be back though.
