I've been using DesignCAD (and its DOS predecessor) for my woodworking
projects and I think it works fairly well. It's not free; but the last
time I checked, the price was under US$100, which seems like a good
price for what I got.
I will warn you, from both personal experience and hearsay, that any
richly-featured CAD package will present a significant learning
curve - probably more or less in proportion to the number of
capabilities built in...
