Creation of a font for a wire text

When using the wire text command, a font is required to draw the text.

Some reminders regarding font terms:


Yellow line	Top line: It is the upper line of the enclosing characters box.
Red line	Center line: It is the middle line of the enclosing characters box. It can change regarding the character type (with or without downstroke, uppercase, ...)
Green line	Base line: it is the line on which is written characters.
Orange line	Bottom line: It is the lower line of the enclosing characters box.

Steps to create a new wire text font:

Create a new 2D Model document.
Create a parameter allowing to drive the character height. (you can have several parameters). They can be used as drivers, to define a catalog, ...
Create as many sketches as there are characters in the font. An uppercase character is not the same as a lowercase. You need 2 sketches for a character.
Each sketch has the name of the character it defines.

The name can be a single character or for exotic character, an hexadecimal value with # has prefix, the name corresponding to the code character of the unicode table as indicated for example on the Wikipedia website. For example: #03A9 for Omega and #20 for space.
The sketch position is not very important. What is important, is geometries position in a sketch, regarding the X axis which is the base line (in green on the image upper).
When a character is not found in the font, TopSolid use the sketch by default, called "Default". it is a rectangle.

Use the Provide function command and select the Wire text function in the drop-down list to allow the Pdm to find it and propose it in a list all available wire text.
Create a family with the contextual command from the 2D model document tab.
This 2 Model document can be defined as a virtual document.
In the family, fill codes or drivers. Defined codes and drivers will automatically appear in the dialog during the creation of a wire text in a sketch.
Don't forget to save and check in these documents.

In the entities tree of the 2D Model document, each character as its own sketch at its name.

The wire text function has been provided.
