Type pdaPointXY
align
Type pdaShapeAlign documentation: portref. Using "bic" is good for input ports on symetric devices. Using "boc" is good for the outputs.For DC/RF pads the "bcc" is a likely candidate.
Allowing shapes to relate to ports saves a lot of equations being re-used and thus makes the file more readable. An example is the polar bend, where the end point is [R*cos(a),R*sin(a)] so if you need to define a small rectangle on the "inside" of the bend, you need lots of equations.
The alignment values are shown below and refer to a rectangle that will fit just around the shape you work on; so for a circle the bil will not be on the bic location but at [-R,R] compared to the center of such a circle.

Type pdaExpression documentation:Expression need to be commonly evaluated by many software, so having a restricted set of math / types and so on is key. In PDAFlow lib2/expr there is a yacc/lex parser available with some unit support as well as double / complex expressions. An alternative is tinyexpr, but this is more restrictive, so may be very unhandy for things like waveguide model expressions.
