New to CAD and old as dirt

MitchellB
Hello folks, how y'all? I am new to drafting of any kind. Well that's not entirely true, I took a beginning drafting class in junior high (in 1975) but I don't know nuthin' 'bout these fancy COM-puters. I was hoping I could get some help with a few issues I'm having.
I have figured out how to draw lines, circles, angles and stuff. My issue is scaling my drawing correctly. I have no idea how to make the scale to the dimension of the part I want to make. For instance I am making a flat plate for a base for a saw I want to build. I know the plate will be 24"x30" with some slots for mounting the motor and some holes for mounting the saw arm. I can draw the rectangle, the holes, and slots but I have no idea how big any of those things are on my drawing. Can someone direct me to the "show me how many inches this line is long" button?

If you just want to know the length of a drawn line, when you click on it and it's highlighted, at the bottom of the screen "Selected Total Length" is shown. Or ask via "Properties" command.
But I guess you want to draw it the right size from the onset. You have to type the coordinates at the command line input.







The @-symbol is to be used for coordinates relative to the last point (the red circle, relative zero). The comma separates x- and y-axis.
Please understand that not every newbie can be given a personal basics schooling. Please read the manual. Unfortunately it's a bit outdated.

Hello MitchellB,

I read your question and wondered how you worked it out.

My first drawing need is something which fits on to letter sized paper at 1:1 so I have not need of scaling, but I realize my case is not general.


Did you "draw" it full size and then use scaling when printing to put it onto paper for printing? When you select
File, Preview there is a drop down box above the drawing space for setting the scale.
It took me a while to figure it out and I printed several empty sheets of paper in the process.

Let us know.
