When you say that you still work mostly with TIN's do you mean with
other software? I did not see where you could cut a cross section from a
TIN in SurvCad XML.

Terry, I am currently using Pacsoft 2000. As you probably know Pacsoft
was bought up and dropped by REI. I have not seen any software that has
the power of Pacsoft's road design, nor the great Cogo entry. However It
does not work very well with Autocad. The other users touched on what my
problems were with my other software.
I didn't know there was a PacSoft 2000. I had been using PacSoft since
before
it was on a PC (HP9000 workstation). It WAS a great package. When
Karen owned the company, support was like Carlson (excellent) and updates
were exciting improvements. REI are civil software terrorists in my
opinion.
I noticed that when watching the movies about deed entry they only
allowed for quadrants to be entered when entering a direction. Can you
specify a NW10.1216? Or a +130.1415 for angle right, -130.1415 for angle
left?
I don't get to do much survey work anymore (used to at previous employer).
I do mostly design. Others may be able to better answer thse questions.
BUT, be sure to check out the EXTENDER command!!!! There is also TA
which is "locate point by turned angle".
Why the grid mesh rather than a TIN or DTM? Does this cause any
troubles with having to specify a small grid size to maintain accuracy
as far as speed is concerned? 3 points better define an irregular shaped
surface than 4?
I still mostly work with TINs. I imaging grids are easier to manipulate
programming wise. I have done extensive analysis of the grid vs. tin
routines in SurvCadd. One does need to make a small grid to insure
accuracy (5ft grid...3ft if its not to big of an area...because at some
point,
small grids over big areas slow the machine to a crawl.)
More important than the # of points defining the surface...its WHAT points
are defining the surface. The TIN is made up of actually data points.
Nothing less and nothing more. The grids are interpolotated.
Can you work with TIN's - edit, plot, export?
Yes....not like pacsoft...ask me for specifics. I DO have methods for
sending information to and from pacsoft, but have weened myself from
even doing this. The latest SurvCadd (XML) comes a long way toward
matching Pacsoft's 3d editing.
What is the smallest size grid that you regularly use for topo's that
are accurate to +/-.25'
Lastly, can I use you as a resource for questions while I'm looking
at this software? You seem to know quite a bit about the software. My
E-Mail is
jlipke@co.siskiyou.ca.us Thanks. JRL
No problem. I am also willing to help out with transition (and any other
way) if you DO get the software.
