Hi. I need to draw a line or lines and give them later some properties. For example, I would like to draw a line with the cursor, then select the line with the cursor and tell the computer the line has certain length or certain diameter or certain color. It is not necessary for the line to change according to those properties, only have them inside the computer and make operations with it.

But, to make things easier, I ask this:

Which is one method of drawing a line that can have properties?

I will solve the other things later. Thanks in advance.
