I guess the first thing I need to do is define what I mean by fundamental. Webster defines fundamental as serving as a basis supporting existence or determining essential structure or function. With that said a drafting fundamental would be considered to be something that is basic or even a foundation for the procedures that a draftsperson would use to do his or her work.
This series of articles is going to be about some of the fundamentals of the graphic language known as drafting. This article is going to be about how to use AutoCAD 2004 to draw a line from a point not on a line perpendicular to a given line segment.
To draw horizontal and vertical lines is easy in AutoCAD all you have to do is to turn on the ortho setting and then all your lines will be strait up and down or left to right. But what would you do if you needed to draw a line perpendicular to a line that was on an angle.
Let’s say I had a line at an incline and I wanted to draw a line perpendicular to it. The way I would do this is I would first either type “L” for line or pick line from the line tool bar or pick line from the draw pull down menu. After I have the line command started I would pick my start point on the side of the inclined line that I wanted to draw my perpendicular line on and then I would hold the shift key down and right click on the mouse and select perpendicular from the shortcut menu and click the line. And *whala* I now have a line perpendicular to a line that is on an angle.
