Knitting Surfaces

I have created a model that is enclosed and is all surfaces. It is a
motorcycle gas tank actually.
I have used the 'Knit' command to stitch together all the surfaces. I
clicked on the 'Try to create a Solid Model' checkbox and the Knit
command does not give me errors/warnings when I submit it.
So my assumption is that my model is now a solid one.

What I am ultimately trying to do is to create section views in a
drawing from the model. The problem I am encountering is that when I
create a section line in the drawing, SW complains saying that the
model view is empty.

I thought that my successful Knit command would have created a solid
model. I also tried to use the Thicken command to thicken the inside
surface of the model, but that fails with SW saying that it is unable
to thicken the surfaces.

I am using SW 2006.

Any help/insight would be much appreciated.

Thx.

Well try using thicken command and give some thinkness to your model
inside which will convert it into a solid.

at the bottom of the knit command box there is a tick box marked "try
to form solid"
tick this and then shell the tank.

Bad assumption - it should give you an error, but it won't. To see if
it is a solid model, look at the top of the feature tree - there should
be a folder called 'solid bodies', and your solid body will be located
in there. No solid bodies folder, no solid body in the model.

There is probably a small gap in your knit surface. It could be
anywhere - the easiest way to find it is to go to tools>check, and hit
the 'check' button. After checking the model, you will (likely) see at
least one 'open surface' in the results list. Highlight that item in
the results list and look at your model in the work window. Any open
surface edge will be highlighted in green - even the little bity spot
that is probably hosing your solid. Then you jsut have to fix it so
you have a single enclosed volume, and you will be able to make your
solid

Good luck,
