Yeah. I spend most of my time trying to work out why things work then
another identical procedure doesn't.
I have to investigate reducing the precision because it seems illogical that
if you set the precision to say 0.1 the vertices of splines are located at
an accuracy of 0.00000001. I thought that the vertices would be positioned
with the same accuracy. Unless of course I am not doing this correctly.
This is my first attempt at doing a large 3D drawing and I've been playing
with it for the last 12 months or so in my retirement. It's not work, It's
supposed to be pleasure but it can be a very frustrating process). It is a
model of a ship and the hull has posed some interesting challenges using
splines, surfaces and solids. I try and work through the problems by
investigating the many variables options available with the aim of
understanding them but at time I just do not get the logic. Happily when I
get pissed off I can shut down and go fishing.
One thing I'm going to check now is how I've set up my overall scale. I
prefer to draw in mm rather than metres and the length of the vessel is
134000 mm (not 134 m). Seems odd to need an accuracy ten billionth of a
millimetre for something that is that long. I'm sure there will be some
suggestion somewhere to suggest how to best set up this scenario. If I scale
the drawing down to metres the accuracy may be as much as 10 millionths of a
millimetre. Better still I might try scaling down to kilometres ( maybe even
light years)
I've given up on the Autocad help because the search function seems to be
useless, again probably some setting is not what it should be for my
requirements, so I rely on chats like this to progress.
Thanks for your comment.
