To modify the default settings for a new graphic in DRAW modify or create the file BWDRAW.DRW.
This file is located on the project node at drive:/WebAccess/Node/config/your_project
You can edit this with draw and even browse to it with DrawDAQ. But once you save it, you have to manually copy it from /drw to project root.
i.e. copy from
drive:/WebAccess/Node/config/your_project/drw
to
drive:/WebAccess/Node/config/your_project
