Why would anyone be interested in anything as mundane as Lettering?
Count me in, the ability to use Letters and Numerals in Designs is essential.
My interests include recreating old forgotten projects, Images of Components used in Equipment Parts and Maintenance Manuals. For a good chunk in my working I worked as a Parts Book Editor Illustrator using old style Graphics Software. Fate determined this to be CorelDRAW [CD]. Like most software, with practice it became easier to use, but it was expensive on time and required continuous effort. The end result was 2D attempting to represent 3D. Regardless it proved capable of meeting demands of a Record breaking Powerboat circumnavigation of the World and for a Navy and their (still currently operating) Fast Patrol Boats, among many other projects. however it is simply not a patch on the S3D results. I like Computer Graphics but LOVE S3D.
What CD could do that S3D, at present cannot, was to allow typed input to be manipulated to provide the needed appearance. I want access to, at least a few choices, of Lettering and Numeral Collections. Creating the needed graphics within S3D has the advantage that along with run of the mill graphics it is easy to create Logos. All of the content here as been created using S3D, with the exception of the Old Images:
The Old
and the NEW Glass removed
Yes, I could have spent longer marrying up the Dial and Body in the Old Image. But clearly it is not worth the effort while the New S3D version can be produced in similar time. The old image was created approaching 50 years ago [using IIRC CD v5 (?)]. Then my Libraries contained Groups that were interchangeable [1 Case with multiple different Dials], hence the separation shown. Creating a mask to hide the righthand extremities of the old Dial ‘under’ the Bezel would require me to get fully tuned in to Affinity Designer [AD]. Retaining access to the thousands of Files when moving from Windows to macOS forced the saving of CD.cdr Files, Adobe Illustrator was available. Much later when my Interest turned into wanting revival action they had to be saved again, this time AD was used. Surprising how many survived these events.
The recreation processes outcome failed to ‘cut the mustard’, for me, fortunately I seized the opportunity to get desired results using S3D. With only a couple of months experience there is much to learn, likely to be prolonged due to rapid development 
New to S3D Users may benefit from Sketching their own Lettering needs within S3D.
Doing this, creating the selection of Character Files shortly to be uploaded, certainly improved my Sketching skills particularly in the practicalities of Constraints.
When there are more than a few Character Graphics in a Design the need for being organised with regard to multiple objects becomes obvious. Like many aspects of computing there are numerous routes to achieve the same goal. Enjoy experimenting. Be sure to hit Folders/Groups/Items:
bottom Left in S3D Display
Note:
- Files contain only Bodies.
- The Numbers, e.g., 100 x 40 x 5 = Height 100mm Length horizontally 40mm x Width of average stroke 5mm [be aware Widths may vary slightly especially Diagonal strokes].
- Lowercase 100/55 signifies [H 100] those with Ascenders or Descenders and [H 55] those without either.
- The Files are Geometric rather than Artistic, I am not an Artist.
- Encouraging Users to create their own Character needs presents them with an opportunity to do it their way.
- The Bodies are Extruded to 0. 01mm, effectively approaching print on the page?
- 100mm was chosen because it simplifies both Sketching and Scaling.
- Be aware that some Height to Horizontal Length Ratios work well during Sketching, one that works well geometrically is Uppercase 11 x 6 x 1 [this will be added to the promised upload.
- Operate the Yellow Handle in Transform > Move / Rotate / Scale and in the Dimension Field that appears type ‘.1’ [or ‘0.1’ if you feel the need] then hit Enter, and 100mm becomes 10mm.
- Obviously choose the Divisor or Multiplier to obtain the desired result.
- This is a work in progress
- Begin, the rest is easy.
The Example, below, suggests one of the methods to speed up corrections /alterations. It also suggests using Folders to keep organised and have the ability to quickly locate specific Characters in your Designs.
You may wish to try this:
Tap the Character Folder [Lowercase-Uppercase-Numerals-etc] to Select/Highlight, this will include the entire content at the same time. > Transform > Move / Rotate / Scale > move the Copy switch to ON > use the Red or Green Arrow to Move Up or Down Copying as it does so.
This also attempts to include two Folders containing the Two Part Characters [i and j].
This removes these two Folders, and contents become parted from one another. You may choose to reunite them [place the appropriate ‘Base’ + ‘Dot’ in Folders and name the folders appropriately]? Be aware this is will possibly change with the upcoming upgrade to iPadOS.
The new Folder will now contain extra Characters every other one ending with ‘Copy’.
Select all of those ending in Copy and Move them to another New Folder, 
good idea to learn how do do this efficiently using just a few further clicks?
Name the Folder appropriately, in the Example ‘the quick brown fox…’ is self explanatory. Sorting the Characters into order as shown is OTT in this case but it could be useful if there is a lot of text subject to frequent changes.
Surplus Characters could be Deleted or simply Hidden. Move additional groups of Characters to Folders as required.
