So, you can have a single text style (say you name it “Simplex”) and you can draw multiple text objects at a given height (say 0.10″) and have the font lineweight vary between very thin, perhaps to indicate something existing, to very BOLD, perhaps to indicate something proposed.Whether inherited through their native property or from a plot style, you can effectively control the “weight” or “thickness” of the font characters ( hereinafter referred to as the font lineweight) by merely changing the lineweight property, again either directly or via a plot style, just like you can with any other entity such as a polyline or arc.Let’s take a look at two important differences. It took several more years before most users started to seriously consider using TTF due to the slowness with which AutoCAD handled these fonts.Ģ0+ years later, we still see confusion sometimes about the differences between the two font types. Most CAD users were split between DOS (and other O/S) and the graphical Windows where TTF could more easily be used. In 1994, with the release of AutoCAD R13, things changed because TrueType fonts were now supported. Shape based fonts were fast to draw and lightweight. But at most plotted sizes, it looks like a perfect “O”, so no worries. There is nothing curved or smooth about it. If you zoom in close enough you can see that the letter “O” for example, is composed of 16 line segments (using Simplex.shx). These are essentially characters defined by vectors. We have seen some people over the years making the switch from shape based fonts (SHX) to TrueType fonts (TTF) in AutoCAD, BricsCAD, etc.įor the first 12 years of AutoCAD’s existence, you did not have a choice, as SHX fonts were your only option.
