VUTRAX 12.0 - CUSTOMING DRAFT BACK-SIDE COLOUR
DISPLAY The VUTRAX 12 version of DRAFT
layer/colours dialogue offers an option [Node Side Hue] which changes
the colour of Surface mount pads (FIXED NODES) and test points (NODES)
when the colour is fixed (rather than following the layer) and the pad is on the
back side or on a side unrelated to one of the outer layers. The normal
setting apply the following variations in hue Back sides tends to
blue (more distant)
Other layers tend to Red (Warning!) The method of specification
is to vary the 3 colour components individually by -128 to +127, the result
being constrained between 64 and 255. If you want different variations within
these rules, you can apply a patch to DRAFT to vary the scheme. Choose
your first try at a new scheme by selecting 6 values. The values must be
hexadecimal, likely values being
80 | for - 128
| C0 | for - 64
| 0 | for no change
| 40 | for + 64
| 7F | for + 127
|
with the 6 values you need being:-
br | Back side | Red | Standard value 80 (-128)
| bg | Back side | Green | Standard value 80 (-128)
| bb | Back side | Blue | Standard value 7F (+127)
| or | Other layer | Red | Standard value 7F (+127)
| og | Other layer | Green | Standard value 80 (-128)
| ob | Other layer | Blue | Standard value 80 (-128)
|
- From the menu system select
[Enable Changes] from (File -> Setup -> Configuration)
- Create file SIDPAD.ASC:
? ? ? ? ? ? 'SIDPAD' ;
br bg bb or og ob 'SIDPAD'
To do this select [Ascii Text] from (Edit) and
enter the lines. If you are viewing this page from the
Internet, [Save As] the frame or simplified page
to Copy & Paste the text. Use of single or multiple spaces
and an initial indent are not important, but all else must be
exact. repace the br..ob with your values.
- Stop any running DRAFT, and from the menu system select
[Option <any>] from (Specify)
and enter the command (by typing or Copy and Paste)
DOPATCH SIDPAD.ASC \VUTRAX\WIN32\DRAFT.EXE
- If this works DOPATCH exits without comment with
the file updated. The original file has the .BAK extension and can be
used to revert to the previous version if you want to.
If DOPATCH complains and requires acknowledgement then you have
probably mistyped the file, or are trying to patch the wrong file or issue. No
change was applied.
- Optionally you can re-protect appropriate files
using
[Protect Files] from (File -> Setup -> Configuration)
Try out the result, adjust the file and continue until you are
satisfied. You will not see any effect unless the node colour are
explicit (rather than folowing layers) and the
[Node Side Hue] control is checked. You may
want to vary the top layer setting to get a satisfactory
effect.
Example patch file making back side more yellow (Red + Green), and
other layers more magenta (Red + Blue)
? ? ? ? ? ? 'SIDPAD' ;
7F 7F 80 7F 80 7F 'SIDPAD'
