typical process is to collect data, d/l it daily, process and draw
linework. After say, 7 days on the project we have 7 drawing files, 7
coord files and we combine these all together for the final product. Note
that each day has distict Ptno. and file names. So now I have this nice
large file with all the linework connected and all 2000+ points and I want
to run contours. I decide to make a new coord file (ie compile01) to make
sure it is all clean. Or I may open an old file and want to update the
coords. I chose the 'simple' command "Update Coord file from Drawing",
and hit go. Then I list all my points. Hmm, the drawing shows all the
points listed at elevations 200 or so but the listed coords are all at
-53... What the!?! Where does this program get this stuff? So after
about 2 more days of going back through and getting the coord file ready,
doing all the 3d line work (and 2d-this is another issue) I run contours.
WOW! Where did that fissure come from? I dont recall locating a 70'
dropoff in the middle of the apartment complex! In fact I did not. The
program has (from my perspective) randomly created some anomoly to which
it has decided contours should be drawn. I will also note various and
seemingly random hills and valleys. A good example of this is that
between the 190 and 192 contour, I have several spot elevations of
appropriate value but around one of them is a series of contours creating
a hole down to elevation 180. How does this happen? I dont have any
linework in this area that could be incorrect and this 188 - 180 contour
set mind you is between the 190 and 192 contour. All I have around are
spot elevations with variances of no more than 4 feet (189-193 or so). So
now I get to spend another 2 days erasing out all the bogus linework.
Also, why is it that I can have one elevation on the screen, another
elevation for the coord file, and point property geometry at yet a third?
And why does a 2d get an elevation of -63.15? Is not the defintion of 2d
only X and Y? The help files even state that a 2d polyline is drawn at
levation '0'. I have had this program for a year, have had several large
and small projects with various amounts of linework and each time I run
into this same problem. Are all the rest of you so familiar with these
issues that you have learned to live with them or work your way through
them? I cam from a DCA prduct created back in 1996 that was absolutely
problem free in contours and point management. one click to update coords
from drawing, a few clicks to draw a poly perimeter, a few clicks to run
the tin, one click to run the contours and BAM! it was done. I am at a
wits end and though I have read every help file on contours and coord
files I guess it is time to travel to Carlson for some extensive training.
Oh, and this is on top of the massive crashes that are the cause of half
day incriments of lost data and time.
