We recently had a client request that we display the Latitude and Longitude of Cogo Points formatted as degrees and decimal minutes. This format seems to have become a standard display format of many hand-held GPS units. Unfortunately, Civil 3D does not contain a built-in option for formatting Latitude and Longitude in decimal minutes. No problem, I thought… I’ll simply use some expressions. But it turned out to be a much more difficult task than I expected… Read on for the details.
Thanks to Richard Sincovec for this concise listing of priority. I forget the order quite a bit, so I’m putting it here for safe mental housekeeping.
If you use Description Keys to assign styles to each individual Cogo Point, then those styles will take priority over the styles in the Point Group, unless you turn on the Point Group Override (on the Overrides tab, in the Point Group Properties).
The order of control is:
1) Style from Point Group, IF the Override is enabled.
2) Style assigned to the Cogo Point itself, if one is assigned.
3) Style from Point Group.– Sinc
You can check out Sinc’s company here and his software here. His toolset seems to strike more of a chord with Survey folks, while EE’s stuff rings with engineers, but it’s always good to check out new stuff.
A post in the discussion group the other day got me thinking. How can one use the AutoCAD scale command on points but preserve the elevations? Short answer – you can’t…with only the scale command. Long answer – there’s a solution – read on.
After looking at the AU 2009 classes being offered and seeing Dana’s tweet, I hopped over to check out her class: More Power to You: “Autodesk Subscription Advantage Packs” for Civil and Geospatial Professionals
So, first glance – Subscription ADVANTAGE Packs? Wha???
Things of interest found in the description, especially to the Civil 3D world are:
Guys and Gals – those are things that Civil 3D 2010 does not have! Have I stumbled upon perhaps what Civil 3D 2011 will highlight? They sound like great additions. Let’s hope that Marley is correct!
