I have a question about Topology?

[Anonymous]

I am running LDD2i with AcadMap. I am completing a polygonal topology for
tax parcels within a section of land, approximately 200 sections which will
consist of 29000 polygons.

My problem is this: I run the topology and spend hours pulling together all
the ridiculously small gaps of less than 0.000001 feet and such. Once this
is done my topology will give me the message, Topology successfully created.

But then for a check, i unload the topology and then reload it, it then
says, topology incorrect but complete!

What is this? and why is this happening? i spend hours cleaning up the
drawing only to have the topolgy actually move the end pts of some lines or
arcs?( thats what it appears to do) Now i have to spend the time hunting
around for these new gaps.

Does anyone know why MAP does this, it is awfully discouraging for the
software to do this?

Any help is appreciated/

MAPTOPOADMIN doesn't display error stack, and there is no info what is incorect.
You may do the same from LISP:
Load the topology
(setq top (tpm_acopen "your topo name"))
(tpm_infocorrect top)
(ade_errshowdlg)
(tpm_acclose top)

(tpm_infocorrect) perfomes audit. If it returns nil, (ade_errshowdlg) must display error stack with all the errors found in audit.
If all your errors are about areas and perimeters, you may ignore them. This is accuracy problem. Shouldn't affect anything else.

Well thanks for the response, but i having trouble
decifering your message.  One thing i do know is that are main objective
here is accuracy.  If this software seems to physically move the end point
of lines, then it is practically useless to me.

Entities are never modified during topology creation. I don't understand what you mean.

thats what i thought too,  but why oh why does
my topology get created successfully with no errors.   I then unload
it then load it with Audit geometry box checked,  and sure enough it say
topology 'incorrect but complete'  then i go look at the NEW red Xs and
sure enough, small 0.000001 gaps everywhere, usually 10, sometimes up to
30.

I can recreate this scenario on EVERY single
section i work in.  I should send you a file once i have ~successfully
completed the topology and have you try to recreate the same results i am
getting.

It does seem that the topolgy is moving objects
slightly and this is trroublesome.

thanks

OK. You can send me file.
But again, topology doesn't modify entities.

again, i tell you it does~!
