As you see in the attachments, the thickness of the arrow line is so lean when export to pdf. How to increase that arrow line thickness? I tried using print to PDF but the result is same. I need the arrow lines to be at least 70% thick as same as the drawing line. or need to reduce the line thickness same as arrow line thickness. Please refer the image 2.
But that is not the question. The question is how to increase the thickness of the arrow line? Changing the arrow length and width options only modify the arrow heads.
