What drawing versions will this version of the Autodesk Civil 3D Object Enabler support?
The Autodesk Civil 3D Object Enabler supports objects created in previous AutoCAD Land Desktop releases. However, if you open a drawing created on an earlier release using the Autodesk Civil 3D Object Enabler and then save the drawing, the object versions are promoted to version 2009, just as if you created the drawing on AutoCAD Land Desktop 2009.
Is the Autodesk Civil 3D Object Enabler the same as the AutoCAD Architecture Object Enabler?
No. The Autodesk Civil 3D Object Enabler and the AutoCAD Architecture Object Enabler are different. When viewing AutoCAD Land Desktop objects in AutoCAD or one of the AutoCAD-based applications (other than AutoCAD Land Desktop), you should use the Autodesk Civil 3D Object Enabler.
Can the Autodesk Civil 3D Object Enabler be installed on a version of AutoCAD prior to 2025?
No. This version of the Autodesk Civil 3D Object Enabler can only be installed on AutoCAD 2025-based products.
Do I have to install the Autodesk Civil 3D Object Enabler in order to view AutoCAD Land Desktop drawings in AutoCAD-based applications?
No. The AutoCAD proxy graphic mechanism (starting with AutoCAD R13) allows viewing of AutoCAD Land Desktop objects in AutoCAD or other Autodesk products that can read drawing files. Turn on proxy graphics before you save your drawings.
How is the Autodesk Civil 3D Object Enabler different from proxy graphics?
The Autodesk Civil 3D Object Enabler does not replace the proxy graphics mechanism of interoperability. Proxy graphics remains a valuable “common denominator” of interoperability across the Autodesk product line. The Autodesk Civil 3D Object Enabler provides a more robust level of compatibility for AutoCAD users, allowing them to benefit from the power of Land objects.
How do I use the Autodesk Civil 3D Object Enabler?
Once installed, the Autodesk Civil 3D Object Enabler works automatically with your existing AutoCAD configuration. If you open a drawing file containing AutoCAD Land Desktop objects, they are “live” and you are able to edit them directly using AutoCAD software commands. There are no menus, toolbars, or command-line features associated with the Autodesk Civil 3D Object Enabler. With the Autodesk Civil 3D Object Enabler you can use existing and familiar AutoCAD commands on AutoCAD Land Desktop objects without the need to learn new functionality.
Can I create intelligent objects using the Autodesk Civil 3D Object Enabler?
There are no commands to create new objects using the Autodesk Civil 3D Object Enabler. Copying existing objects, however, is supported, and objects retain their intelligence.
How can I control the drawing units when I perform a Map query on an AutoCAD Architectural Desktop drawing and an AutoCAD Land Desktop drawing in an object-enabled AutoCAD Map 3D?
To control the drawing units when performing a Map query draw, you can use the -aecdwgunits command, which has been added to the Autodesk Civil 3D Object Enabler.
You can use this command to set the drawing units before performing a query draw in which you query drawings with different units, such as a AutoCAD Land Desktop drawing and an AutoCAD Architectural Desktop drawing.
To use this command, at the command line, type -aecdwgunits (including the dash), and then set the drawing units by using the prompts that are displayed. These prompts control drawing units, drawing unit display format, linear display precision, and whether objects from other drawings are scaled on insert. The scale on insert prompt is shown below:
Scale objects from other drawings upon insert? [Yes/No] <Y>:
When combining AutoCAD Land Desktop and AutoCAD Architectural Desktop drawings using Map query draw, it is recommended that you answer “Yes” at this prompt prior to querying either drawing, or the drawings may not be scaled properly.
If there is not already a Drawing Setup object in the current drawing, then this command creates a Drawing Setup object with the settings you specify.
How do I install the Autodesk Civil 3D Object Enabler?
See Accessing and Installing the Autodesk Civil 3D Object Enabler.
How do I distribute the Autodesk Civil 3D Object Enabler install?
The Autodesk Civil 3D Object Enabler is a freeware application that you can distribute to anyone who wants to view your drawings. However, the Autodesk Civil 3D Object Enabler alone cannot display your drawings. You must have an installed copy of one of the Autodesk products listed in Using the Autodesk Civil 3D Object Enabler for AutoCAD Land Desktop 2009 Object Data.
How do I verify that the Autodesk Civil 3D Object Enabler is installed properly and running?
When you open a drawing containing one or more AutoCAD Land Desktop custom objects, a message displays at the AutoCAD command line saying that the AecBase40 and AecCivilBase modules have been loaded.
Why do I still see the Proxy Information Dialog Box when I open a drawing?
The AutoCAD Proxy Information dialog box for AecDraft.arx is displayed when you open a drawing that contains Land Desktop dynamic line label objects.
Are there any AutoCAD variables that affect the Autodesk Civil 3D Object Enabler?
When you are using the Autodesk Civil 3D Object Enabler, it is recommended that you use the Object Detect And Command Invoke option in AutoCAD Options.
To select the Object Detect And Command Invoke option
- Enter OPTIONS at the AutoCAD command line to display the Options dialog box.
- Click Open And Save.
- Under ObjectARX Applications and Demand Load ObjectARX Apps, select Object Detect And Command Invoke.
This option checks for any custom objects that exist in a drawing and loads the parent ARX/DBX application.
When you want to use the Autodesk Civil 3D Object Enabler to view custom objects, set the Demand Load ObjectARX Apps option to Custom Object Detect or Object Detect and Command Invoke.
