I'm looking for some way of making a pattern and having it input
directly into a computer accurately. The surface is a bit irregular and it
will be curved in places. I'd like to be able to get some sort of input
device that I run around the inside dimension of the item and it draws a
pattern or outline in the computer. We'd be possibly using a program like
Corel Draw unless someone else knows of a drawing program that would output
to a DXF, PLT, or NC data format.
The surface we'd be tracing the inside dimension of would most typically
be carpeted. Ideas were thrown at me about using a mouse or a pen-like
mouse device but since the mouse/pen ball position is sensitive to changes
in the angle, this wouldn't yield an accurate pattern and it would most
likely fill up with debris, making it hard to keep clean.
I looked at a couple of digitizer input devices but since they require
having an set absolute zero point, they're typically either attached to a
tablet or are on an arm to keep the reference point. Since this will not be
an easy surface to get to, arms and tablets are not feasible.
If anyone has any ideas or knows of a company with a product which will
do hat I need, please let me know.
