Edge dimensions

An edge is a one-dimensional border of a figure with at least 2 dimensions. There are 4 edges of a square and 12 edges of a cube. However, in software for 1990's versions of Windows, programs that ask you to draw shapes often have options for edge width, which implies an edge DOES have 2 dimensions. Anything it's important not to confuse here?? Georgia guy (talk) 20:45, 23 August 2019 (UTC)

Yes, don't confuse a 1-D edge with its 2-D representation. A line with zero width would not be visible. Dbfirs 20:58, 23 August 2019 (UTC)

And in raster graphics, that thickness is in pixels. SinisterLefty (talk) 22:09, 23 August 2019 (UTC)

Also, it's not just 1990's software, specifying the line thickness in some form is common to just about all drawing programs. However, it may be called "Pen", "Brush" or something else, or may use icons with no text name shown. SinisterLefty (talk) 01:08, 24 August 2019 (UTC)

If you want a truly one-dimensional edge, set the width of the edge to zero, set the color to invisible, or simply turn it off (which of these you can do will depend on your software). Then the shape will define the one-dimensional edge without showing its two-dimensional representation. ubiquity (talk) 16:24, 30 August 2019 (UTC)
