Hi everyone. I know that construction lines were used when drafting was done by hand. Now, we do everything on the computer. So, how are they used on the computer? Also, how are guidelines used in autodesk? Were they not used in manual drafting also? How are they used in computer drafting? Also, where would I see both types of lines? I tried scouring the internet for answers, but there were none, so I am turning to the experts on this form. Thanks in advance for the feedback and the help! Greatly appreciated!
