AutoCAD Map 3D 2008 - Import/Export of Shape Files

Changes in the performance/results when importing and exporting Shape files in AutoCAD Map 3D 2008 are attributed to changes to the import engine.

The Import engine in AutoCAD Map 3D 2008 is based on the FDO provider for Shapefiles, where in the past, many previous versions used FME from Safe Software.

The following issues are a known "side affect" of this change to the import engine and have been logged as Change Request's with the Autodesk Development Team, to be resolved with the AutoCAD Map 3D 2009 release

• Imported entities are assigned an object colour of "white"
• The inclusion of "Default_" as a prefix to all layers

AutoCAD Map 3D 2008 - Exporting to Shape with Long Field Names

Test Description

To export data to a Shape file and force the Field Names above the 10 character limit in the dbase file and observe what the resulting Field Names are in the output dbase file.

 

Test 1 - Numerical changes to the Field Names

During export, I modified the Field Names in the export dialog, appending numbers to selected Fields to exceed the 10 character limit

The resulting Field Names in the dbase file...

For some reason the Field Names have also been appended with an additional letter (N or C), corresponding to the Field Type, "C" for character or "N" for number.

Original Field Name	Modified Field Name for Export	Resulting Field Name in dbase File
COMM_BOARD	COMM_BOARD1	COMM_BOARD1N
COM_BOARD	COM_BOARD23	COM_BOARD23C
CREATED_DA	CREATED_DA2	CREATED_DA2C
DATE_CREAT	DATE_CREAT1	DATE_CREAT1C

 

Test 2 - Alphabetical changes to the Field Names

During export, I modified the Field Names in the export dialog, appending letters to selected Fields to exceed the 10 character limit

The resulting Field Names in the dbase file...

Again, for some reason the Field Names have also been appended with an additional letter (N or C), corresponding to the Field Type, "C" for character or "N" for number.

Original Field Name	Modified Field Name for Export	Resulting Field Name in dbase File
COMM_BOARD	COMM_BOARDA	COMM_BOARDAN
COM_BOARD	COM_BOARDAB	COM_BOARDABC
CREATED_DA	CREATED_DAC	CREATED_DACC
DATE_CREAT	DATE_CREATD	DATE_CREATDC

Conclusion: well at least it's consistent... looking forward to the SHP Import/Export Improvements in the 2009 release of Map 3D

MapGuide Script Error

Following a recent implementation of MapGuide Enterprise, I was asked to resolve the following script error.

The error occurs if you have the Task Pane disabled in your MapGuide Layout. As a number of default commands use the Task Pane to show/request user information and the Task Pane must be available.

This error can occur when viewing your application in your web browser, or when previewing the MapGuide Layout using MapGuide Studio.

The following commands use the Task Pane...

• Measure
• View Options
• Help

MapGuide Open Source 2.0.0 Release Candidate 4 available

The MapGuide Open Source project team has made MapGuide Open Source 2.0.0 Release Candidate 4 available.

Release notes: http://trac.osgeo.org/mapguide/wiki/Release/2.0/Notes.

Documentation: http://mapguide.osgeo.org/documentation.html

Downloads: http://mapguide.osgeo.org/download

The main features in this release are integration of the Fusion framework, replacement of FastCGI with ISAPI and Apache mod and numerous bug fixes.

The 2.0 milestone page for the complete list of new features: http://trac.osgeo.org/mapguide/milestone/2.0

The last few release candidates have been working to get joins working again; joins were enhanced to allow for theming and filtering on the joined attributes, but this had also introduced some regressions in behavior. The regressions should all be gone now.

CAD & GIS - Apples to Apples...

Neal Niemiec has recently posted an excellent article on his CAD & GIS Integration blog reviewing some misconceptions with respect to Autodesk and ESRI GIS capabilities.

Take a look, it is a very interesting read...

SDF Theming in AutoCAD Map 3D

After running some recent Map training sessions I have had a comment come up regarding the theming of SDF layers in AutoCAD Map 3D. When you go to edit the style of an SDF layer in the Display Manager in AutoCAD Map...

"Why is it that you can only edit the Point Style for that layer, how do you set the style for Line and Polygon features?"

This of course applies to the new multi-feature SDF files.

The confusion is actually in the interface. When you first access the Style Editor to format the style of an SDF layer, you are presented with the palette below...

The palette shows the Scale Ranges and a preview of the Line, Polygon and Point styles at the top of the palette.
The palette then shows the Point Style theme settings at the bottom of the palette...

So where are the settings for Line and Polygon?

Unless you adjust the size of the palette, or notice the scroll bar down the right hand side of the palette, you appear to only have access to the settings for points.

Here's the same palette re-sized to show all of the settings...

I believe the confusion is caused in the initial view of the palette, which unfortunately is sized so that the Line and Polygon settings can be easily overlooked.
