Drawing comparison does
not support all object types in AutoCAD and AutoCAD specialized toolsets.
The DWG Compare feature does not support all object types in AutoCAD. The exceptions include OLE
objects, cameras, geographic data, GIS objects from Map 3D, non-DWG underlays,
images, coordination models, and point clouds.
When performing a
comparison, importing electrical and mechanical objects is similar to the
copy/paste behavior in AutoCAD, which is different from how the AutoCAD
Electrical and AutoCAD Mechanical toolsets normally operate. As a result, some
of the toolset components lose their custom functionality.
The following tables
describe the primary limitations for the comparing drawings created with the
AutoCAD Electrical and AutoCAD Mechanical specialized toolsets.
Electrical
objects
|
Output
after using compare import command
|
Wires
|
Wires will lose some
of the properties like color and size. The wire data is available in the
project as layers and cannot be imported into the drawing comparison mode.
|
Wire number
|
The wire number is
disconnected with the wire. The imported wire number will lose the
relationship with the wire.
|
Source/Destination
arrows
|
The source/destination
arrows imported will not have the correct wire numbers. The source arrows and
the destination arrows will also lose the relationship to each other.
|
Schematic terminals
|
These blocks will
retain their electrical properties, however the terminal wire numbers will
not be updated.
|
Balloons
|
The imported balloons
will not be grouped and will be available only as exploded geometric objects.
|
Mechanical
objects
|
Output
after using compare import command
|
Mechanical symbols
|
Importing a mechanical
symbol that's attached to an object also imports the associated object. For
example, if a weld symbol is attached to a rectangle, importing the weld
symbol will also import the rectangle object.
|
Standard parts
|
Importing a standard part
will not update the Bill of Materials (BOM) unless you also select the
associated part reference of the standard part.
|
Finite Element
Analysis (FEA) objects and other calculation objects
|
Importing an FEA
object will not include its mechanical data and the object will be imported
as a block.
|
Architectural
objects
|
Output
after using compare import command
|
General AEC objects
|
Importing an
architectural object (AEC object) that's attached to an AEC object also
imports the associated object. For example, if a door or window is attached
to a wall, importing the door or window object will also import the
associated wall object.
|
Architectural
objects
|
Output
after using compare import command
|
General MEP objects
|
Importing an MEP
object that's attached to an MEP object also imports the associated object.
For example, if a duct fitting is attached to a duct, importing the duct
fitting will also import the associated duct object.
