C3D 2009 vs. 2011 save-times on Win7

On July 18, 2010, in 2009, 2011, Best Practices, Cad Management, Vault, civil3d.com, by Mark Spatz, P.E.

If you are in the process of upgrading to Windows 7 (64-bit) and are still using Civil 3D 2009 you might notice files take longer to save.  In this example we are saving a 65mb file (very large file).  To save the file to the C: drive with Civil 3D 2009 on Windows XP it takes 45 seconds.  Whereas, with Civil 3D 2009 loaded on Windows 7 the same file takes 1.5 minutes to save.  So essentially, the file takes twice as long to save.  I have no idea why it takes longer to save, it just does.  Also note, C3D 2009 is not officially supported on Win7.

However, there is a light at the end of the tunnel.  Civil 3D 2011 (64-bit), with ISAVEPERCENT set to 50% – after the 1st two saves – only takes 15 seconds to save the file.  So essentially it takes 1/3 of the time it took C3D 2009 to save on XP; an increase in proficiency.

After the jump see some more save-time results.  Including over the LAN and WAN (w\ Riverbeds).

Polylines, Alignments, and PI’s

On July 7, 2010, in 2007, 2008, 2009, 2010, 2011, Alignments, Polylines, civil3d.com, by Matt Kolberg

You’ve created an alignment from a polyline, but upon inspection, there are no PI’s (line extensions) at any of the curves.  Why?  And, how can can I get ‘em?  Read on…

Civil 3D Annotation Scaling Revisited

On July 5, 2010, in 2008, 2009, 2010, 2011, Annotate, Fundamentals, General, Labels, Styles, by Dana Probert

One of the most frequently-asked questions in the Civil 3D discussion groups has to do with how scaling works for Civil 3D labels and tables.  The question usually comes up phrased as “How come my text looks good in modelspace, but is huge (or tiny) in paperspace?” or “How come my Table columns overlap in paperspace?”

At first glance, Civil 3D labels and tables seem to scale much like Annotative Text.  However, Civil 3D Labels and Tables were capable of their auto-sizing behavior long before AutoCAD got Annotative Text, and do not use the Annotation Scale at all.  Instead, Civil 3D Labels size according to their own rules.  Read on for more…

Displaying Lat/Long in Decimal Minutes

On July 1, 2010, in 2007, 2008, 2009, 2010, 2011, Labels, Points, Styles, by Dana Probert

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.

Customizing Civil 3D

On June 12, 2010, in 2008, 2009, 2010, 2011, API, Programming, by Dana Probert

One of the greatest strengths of Autodesk products is the extensive Application Programming Interface (API), which gives users the ability to customize and extend the functionality of the software. In the past, some favorite techniques included using Visual Lisp or VBA to create any needed customizations. However, technology has been changing, and with Civil 3D, we need a somewhat different approach…
