- Hi there,
Last week I was on Iceland again - and this time I spent some relaxing time on the Blue Lagoon. www.bluelagoon.com
Not bad, not bad at all... Half way between the airport and the city of Reykjavik.
In Civil 3D, as you are well aware of, it is very easy to create Surface of almost any kind.
I just want to give some hints to new users, to open up for a "broader mind", on how you can use it in an "extended" way.
For example, one thing is that because of the linked objects, you can relate a Surface easily to another.
If you then design a simple parking with elevations, Feature lines etc - present it with contours etc, like below:
What you can easily do, besides assigning a number of Surface Labels, is creating Slope arrows on the Surface.
Like below:
To avoid Slope arrows on the whole Parking Surface (including the Grading slopes etc) and just keep it over the paved area, you can create a new Surface.
In my case called "Parking Analysis". Then under that Surface, Definition, use "Edit" - "Paste Surface" and add the Parking Surface.
Apply a Surface Style that has Slope Arrows "ON" and set the "Analysis" parameters on that tab.
After that is done you simply put a Border to it using a Polyline etc from the "Curb stone" and then you don't have the Slope Arrows on the Grading anymore.
In my case, below, I get only a few Arrows. That's because we get one Arrow per Triangle.
If we add more Points to the Feature lines, preferable after we have given them proper elevations, grades, mid/low/high points etc, we can get more triangles.
Use the button with the Yellow triangle "Insert PI". Then select the Feature line, and type "I". Set a distance that will divide the Feature line in to more segments. In my case I use 15 meters. See the small grey triangles presented.
This gives a more dense triangulation as the Feature lines gets more segments. See the orange Triangles below that correspond to the Slope Arrows.
Of course you don't present the Triangles in YOUR Style... ;-)
Now I am really looking forward to AU next week.
Hope to see some of you there!
Best regards / Ove Cervin

Live from the Civils 2008 Show - London
Posted 11/18/08 by Jack Strongitharm
Its Civils Show again this week and myself and my reseller colleagues from the UK are in London showing Civil 3D on a daily basis.
If you are interested in coming you can still register and arrive on the day.
We are here until Thursday
www.civils.com
Daily line up
10am Autodesk - AutoCAD Civil 3D and NavisWorks 2D to 4D
Explores how Civil 3D can be viewed in a 4D environment, tracking time during
the construction sequence. Including clash detection against other civil and
building objects for design collaboration
www.autodesk.co.uk/civil
ME
11am Benchmarq - Automated Sections & Volumetric's
This presentation will show how to very quickly and easily create cross sections,
long sections and volume reports from existing survey data and the proposed civil
engineering design using Civil 3D. This demonstration will show how much time
and money can be saved over standard AutoCAD when doing typical everyday civil
engineering design tasks.
www.bmarq.co.uk
Carl Alford
12pm Excitech - Project Documentation with AutoCAD Civil 3D
Producing high quality production drawings and project documentation using
AutoCAD Civil 3D.
www.excitech.co.uk
Dave Bosworth
2pm Excitech - Design Review & Analysis using RDV
Analysing design data and reviewing designs by visualisation using RDV
www.excitech.co.uk
Dave Bosworth
3pm Benchmarq 3D Visualisation
This demonstration will show how to create stunning visualisations using
Dynamite DVSP, by linking dynamically with a Civil 3D model this visualisation
software allows users with minimal visualisation experience to create
photorealistic fly-throughs of their civil engineering design.
www.bmarq.co.uk
Carl Alford
4pm Datech - Importing Survey Data into Civil 3D
The starting point for most Civil Engineering projects; this session concentrates
on importing and creating 3D geometry from site survey data utilising the tools
within AutoCAD Civil 3D.

Getting our hands dirty
Posted 11/12/08 by Jack Strongitharm
So last week we decided to go and do some surveying as it is fine showing software with data but if you actually created it yourself makes all the difference. (plus I think that our data from Wigan Council has been seen quite a bit!)
Also to look more carefully at the workflow of transferring raw survey data through our survey capabilities in Civil 3D.
With the help of our colleagues at Trimble and Leica we were provided with some kit and some initial help to get us running.
So our site selection my seem a strange one when we could have gone anywhere, but Stoke Park in Guildford, Surrey in England was where we went. Why there you may ask, well we did some surveying there a couple of years ago and it was the nearest public field to Farnborough that we had other mapping data for. Its a shame!
So from Leica we had Mark Smith providing us with a TCRP 1205+ System 1200 Total Station which was a reflectorless EDM which tracked you with the survey pole and logger.

From Trimble we used a GPS system called R8 GNSS GPS and a TSC survey Controller

Me and my bald head!

It was amazing how quickly we did the survey, things have definitely changed since my time surveying, with mobile phone connection to OS base stations, quick coding, the total station following your every move...
Also we did a laserscan of the site with Leica and their ScanStation 2 equipment which was even quicker than us running around.

Also I put what was a 440mb ptx point file into Navisworks and created a 20mb NWD file
So in Civil 3D, using 'Trimble Link' and 'Leica X-Change' from the RAW data using Survey in Civil 3D we get all the points with coding, linework with our coding that included begin, curve type codes for automatic linework creation.
Not bad for a day and a half, especially us lot.
Many thanks to both Leica (Mark Smith, Paul Burrows and Steven Ramsey) http://www.leica-geosystems.com and
Trimble (Mark Harper, Tor-Erik Djupos) www.trimble.com
for their help and providing us with the equipment for the two days.
