There are two ways to open an Advance Steel model in pure AutoCAD:
Autodesk offers downloadable enablers that you can use to access, display, and manipulate object data in applications different from their native environment.
In order to open Advance Steel 2016 models in pure Autocad 2016, on workstations that do not have Advance Steel 2016 installed, you need to install the appropriate Object Enabler (OE).
The Autodesk enabler for Advance Steel 2016 model objects is Advance Steel Object Enabler 2016 whitch can be downloaded from the Autodesk Knowledge Network.
On workstations that do have Advance Steel installed, it is not necessary to install the Advance Steel Object Enabler 2016 because the object enabler already part of the full Advance Steel 2016 installation.
The Advance Steel Object Enabler 2016 is only compatible with Advance Steel 2015, Advance Steel 2015.1 and Advance Steel 2016 files.
To open an Advance Steel DWG model in pure AutoCAD® without using the Object Enabler, you need to explode the model to ACIS. Prior to this, all the elements that cannot be exploded need to be manually deleted. For easier selection, use the Quick Select function.
Open the "Quick Select" dialog box: Tools > Utilities > (Quick Select).
Make the following settings:
From the "Object type" drop-down list, select the type of elements you want to delete.
All the types with names containing the "AST" prefix are Advance Steel objects. You need to keep the following types: ASTGRID, ASTBEAM, ASTBEAMFEATURE, ASTPLATE, ASTSCREWBOLTPATTERN, ASTPLATEFEATURE, ASTBEAMHOLEPATTERN, ASTPLATEHOLEPATTER. All the other Advance Steel object types must be deleted manually.
To delete Advance Steel objects from external dwg
This step is necessary in order to delete all the remaining Advance Steel objects that couldn't be manually deleted.
In a new dwg file, use the function "Delete all AS objects from external dwg".
Save it, then re-use "demandload" command and set the value to 3.
The file can now be opened in pure AutoCAD® on any computer and it cannot be rolled back to the Advance Steel model.
