I read your message with some delay, but...
While making scripts I digged out most of the schematic and symbol formats. They
are not complete but the existing stuff should be quite accurate. At least my
scripts work when they parse the files according to it.
If you have questions, please ask.

The Format how ViewDraw stores schematics :
-----------------------------

Schematics are in ASCII text format.
They share several lines with the symbol file format.
In the beginning of each line there is a letter which indicates the object in
question.

V : version 1 fields.
Eg. V 50
Other fields : internal version number

K : license 2 fields.
Eg. K 199811641700 RESU
Other fields : ? OriginalName

Y : Symbol type. 1 field.
Eg. Y 0
Other fields : SymbolType

D : Symbol size. 4 fields.
Eg. D 0 0 60 40
Other fields : xpos ypos Width Height

Z : Sheet size. 1 field.
Eg. Z 10
Other fields : SheetSize

i : ? 1 field.
Eg. i 6
Other fields : ?

I: Component. 7 fields
Eg. I 3 Lm7805 1 550 480 0 1 ' # must have trailing '
Other fields: component id, symbol name, sheet number, xpos, ypos,
orientation, scale

L : Label for the previous component. 9 fields.
L 670 930 14 0 4 0 1 0 DIO-GEN2-CC.1
Other fields : Xpos Ypos FontSize NotUsed Orientation Locality Visible
Inverted Name

A : attribute. 7 fields. # attribute line
directly follows the component or pin or net it belongs to.
Eg. A -3 10 10 0 7 0 REFDES=N?
Other fields : X Y FontSize NotUsed Orientation Visibility Name(=Value)

C: Pin. 4 fields # Pin of the above component.
Eg. C 4 4 29 0
Other fields: ? ? InternalPinNumber ?

X: Pin. 2 fields # Pin of the above component.
Eg. X 23 0
Other fields: InternalPinNumber ?

Q : Defines font, line type and color definition. Affects the previous object.
Eg. Q 1 5 0
Other fields : ?

N: Net 1 field
Eg N 8
Other fields: NetNumber

J: Joint 3 fields # joint relating to above net
Eg J 530 540 3
Other fields: xpos, ypos, JointType

S: Segment 2 fields # segment of above net
Eg S 2 1
Other fields: LowJointID, HighJointID

B: Bus 2 fields
Eg B 2 4
Other fields: ? ?

E : End

JointType : 2 = Wire connects to a component pin.
3 = A corner in the wire.
5 = Wire connects to a segment of another wire (shown with a
dot).
