# Quick cad question

I have to draw a line that goes E for 4' S for 2' E for 120' N for 2' E for 4' then N for 1.5'
I can do it, but it seems like I am taking a long time and going through an awful lot of steps. Is there and easy to draw this line?

Hmm.. I use SolidEdge not AutoCAD, but if AutoCAD can draw vectors you can try that, or define a function (which in your case would be dot product of those vectors)

All CAD packages have some way of:

1) Scaling the page. Scale the page so the line fits inside the boundry.
2) Drawing a line from point to point. They all have a way of specifying a start point, a length and a direction. It should be as simple as:
- clicking a "start line"h button,
- moving the cursor to some point on the page and clicking to specify the start point
- specify distance (4') and direction (east = 0 degrees)
- clicking or enter to make the line appear
- repeat for the other lines.

Hope that helps.

basically that is what I'm asking. right now I draw a line then modify it by extending it. On extend I can specify a length I want to know if there is a way to do it in one step.

If you are using AutoCad, use the "@" symbol when typing in your coordinates. The "@" symbol denotes relative position in stead of from the UCS. Start your line at where ever you want, when it asks for the second point (E for 4'), type in "@4,0" or "@48,0" (depending on how you want to do the general units). That way all you have to do is type in the endpoints. Should take about 3 seconds to do.

thank you, you have my undying gratitude.

You can also use relative polar coordinates $@r<\theta$. This is useful if you want to go off at non-right angles from your previous spot.
