Internal Error When Creating a Survey Database

June 27, 2013

When creating a new local survey database, you might come across an error stating that it cannot open the shared memory region.

The cause of this seems to be the Windows User Access Control (UAC).  You need to set this to Never Notify…

Survey Database is “Read-Only”, or “Locked”

August 8, 2012

I had a call this morning from a customer that stated their survey database was locked and he couldn’t do anything with it.  Usually what this means is that it is in the “Read-Only” state.  You can visually see that it is “read-only” by the icon that appears next to your survey database name.  See image below…

After checking the folder for permissions, which customer had Full Control, it occurred to me that the execution of opening the survey database might not be the correct way.

The correct way to open a survey database is to right-click on it, then select Open for Edit.  The customer was double clicking the survey database to open it.  What happens is when you double click it, it opens in “Read-Only” mode.  The image above was opened by double clicking the survey database.  The image below is opened by right-clicking on the database name and selecting Open for Edit.

Label Survey Figures

April 19, 2012

If you have taken my Civil 3D Fundamentals class, you know that we bring survey data in, and the linework that is drawn are survey figures.  So in order for us to label the parcels created from the linework, we have to do a Mapcheck and then create a polyline from the Mapcheck.  Then we had to created a parcel from that polyline.  All of that just to label the parcel.

With Civil 3D 2013 you are able to label Survey Figures.

To read more about this, go to Being Civil’s blog and read AutoCAD Civil 3D 2013 New Feature: Labeling Survey Figures.

Elevation Adjustment in a Survey Database

December 22, 2011

I get many calls on adjusting point elevations all at once in a drawing.  Most people try to adjust the elevation using the Datum method as shown below…

This method prompts you at the command line to adjust the datum by a value.  You enter a value and nothing happens.  This is because it’s in a survey database, hence, the reason for a survey database.

I’m going to walk you through the correct method in adjusting elevations in a survey database.

First you will need to pick a point as to which to do your adjustment from.  In this case we are going to use point number 504.

6-27-2011 3-12-14 PM

Notice the elevation for point 504 is 131.88.

We start by right-clicking on the Survey Database’s name and selecting Translate Survey Database…

6-27-2011 3-12-14 PM

This will open up a wizard.  On the first page, you have a few options for input.  All I am going to do is input the point number 504 and hit the enter key…

6-27-2011 3-12-14 PM

As you can see in the image above, once I hit the Enter key, it populates the Northing, Easting, Elevation and Description.  Click Next.

The next page prompts you for the rotation.  Since we are not rotating, and we are ONLY doing an elevation adjustment, enter 0 and press Next…

6-27-2011 3-12-14 PM

The next page prompts you for a destination point and elevation adjustment.  We are ONLY concerned about the elevation.  Here we are going to enter –2.00.  This will adjust the points down.  If you want to adjust them up, then you will enter a positive value.

6-27-2011 3-12-14 PM

Click Next.  The last page is a summary of the values we just entered.

6-27-2011 3-12-14 PM

Click Finish.

Here you can see the desired adjustment…

6-27-2011 3-12-14 PM

Keep in mind that this adjusted ALL my points –2.00 feet.

Everyone have a Merry Christmas and Happy New Year.  I will see you in 2012!!!
