Do you use STB or CTB? CTB has been around since day one of AutoCAD. Most users may not even know that they use it – but they do. STB is newer but has been around for a while. But it has not taken over the AutoCAD world by storm.
If you are trying to choose which one to use there are some good things and bad things about each. Here are a few…
- Most legacy drawings use CTB
- You are most likely have already got this down pat.
- It is used by most CAD users
- Most CAD users “eyes” can quickly define thickness by color
- STB has a shorter list of options when picking pen weights. Users will not have to guess or refer to a chart to see what color number to use.
- When using STB you don’t have to remember what color equals what weight.
- Ability to plot layers that use the same colors with different line weights, screening values, colors etc.
- Since you really only use about 5 or 6 different line weights and a couple of screening values, you won’t have to manage 255 color settings of a CTB file
- SketchUp and Revit do not use pen weights. You would be moving toward simplification of plotting options.
- You can swap either CTB or STB easily to create a different plot look.
- E-transmit sends all of the stuff needed. When you send out the border and sheets the plot table goes along.
- Exchanging PDF files for updates so CTB or STB does not matter.
- Exchanging files can be done with DWF Underlay or PDF – no adjustments needed on pen weights.
- Autodesk is not pushing one way or another. Development on both is more or less stagnant.
- STB Plot style name may not be easily understoodOthers may not understand them outside your firm.
- The conversion of existing data to STB will take time
- STB not as widely adopted in general.
- Getting everyone up to speed on using STB files may take time.
- 255 colors promised but not all can be used since some cannot be used.
- You have to manage all 255 colors
- users can pick all over the map from the 255 colors/weights
