AutoCAD Commands and AutoCAD Civil 3D Objects
 
 
 

The following topic provides information about AutoCAD command operations on certain AutoCAD Civil 3D objects and the results.

All AutoCAD Civil 3D objects support the AutoCAD List, Explode, and Erase commands.

NoteExploding an object results in an unnamed AutoCAD block. Exploding again results in a base AutoCAD entity.

Most AutoCAD Civil 3D objects support other commands to some degree. These commands include Copy, Move, Mirror, Offset, Scale, Block/wBlock, Rotate, Trim and Extend.

NoteYou can get the “Copy” behavior by using the Home tab Modify panel Copy command on the ribbon, or by entering COPY at the command line or by using the Basic Modify Tools Copy command on the shortcut menu. You can get the “Block/Wblock” behavior by using the Clipboard Copy or Clipboard Copy With Base Point commands on the shortcut menu, pressing Ctrl + C, or entering WBLOCK at the command line.

Supported AutoCAD Command Notes

Surface

If the surface is erased or exploded, profiles and sections that reference that surface become static.

Mirror will create a copy but will not honor the mirror settings.

Point groups used in the surface definition are included as part of the Wblock.

Point

When Wblocking and Inserting points, or copying points, a dialog box is displayed to resolve number conflicts.

Table

Wblocking a table also copies the required geometry. For example, the points are copied along with the point table.

Alignment

Exploding or erasing an alignment explodes or erases all objects that are dependent on the alignment (such as profiles, profile views, sample lines, sections, and section views).

Copying the alignment will create an alignment with a new name in the same site. All dependent objects will be copied and included with the new alignment.

Wblock/Insert will copy the alignment and all dependent objects into a new site.

Parcel (select parcel label)

When copying or Wblocking a parcel, the dependent parcel segments are included. If the objects are inserted into the same drawing, a new site is created.

Only the parcel labels can be moved.

Parcel Segment Lines

Wblocking/Inserting the parcel segment lines creates segment lines in a new site.

Grading

There are two distinct copy operations which can be done on a grading object. Copying the footprint feature line or individual target line creates a new feature line in a new site. Copying the entire grading object copies the footprint, target, and criteria.

The footprint can be moved. The target line cannot be moved.

If the grading criteria references a surface, the surface will be included in a Wblock/Insert operation.

Profile

Erasing a profile or section erases it from all profile or section views.

Profiles and sections can only be moved vertically within a view.

Profile View

If the profile or profile view is Wblocked, all objects required for the profile or profile view (such as the surface, alignment, profile, sample lines, and sections) are copied. If the objects are copied into the same drawing, a new site is created.

Sample Line

You cannot copy or move a Sample Line

Section

Erasing a profile or section erases it from all profile or section views.

Profiles and sections can only be moved vertically within a view.

If the sample line, section, or section view is Wblocked, all objects that are required for the sample line, section, or section view (such as the surface, alignment, sections, and sample lines) are copied. If the objects are copied into the same drawing, a new site is created.

Assembly

The names of assemblies and subassemblies are incremented when copied. Copying an assembly copies the assembly and all dependent subassemblies.

Mirror will create a copy but will not honor the mirror settings.

Corridor

Copying or Wblocking a corridor copies all of the dependent data such as assemblies, alignments, and surfaces.

Pipe Network

Network Objects are not accessible through Object Enabler environment.

Pipe

Copying a network part profile will create a copy of the parent network part (pipe or structure).

Structure

Copying, mirroring, arraying, and offsetting pipes and structures updates the references of any connected parts.

Copied pipes and structures will be in the same network.

Moving or rotating a structure causes any connected parts to move with it. (the connections are maintained).

Moving or rotating a pipe breaks the connection to any connected parts.

Scaling a pipe or structure affects position but does not affect size.

Wblocking pipes and structures copies all dependent objects.

Survey Network

Using the copy command on a survey network creates feature lines. The move command disassociates the figure from the model.

Survey Figure

Using the offset command on a survey figure generates a feature line object, not a survey figure.

The move commands dissassociates the figure from the model.

Mass Haul Line

Using the explode command keeps the layer and display settings.

With the Extend command, the object can be selected as an edge to extend to, but cannot be selected to extend

With the Trim command, the object can be selected as a trim edge, but cannot be trimmed

If the mass hauls is Wblocked, all objects that are required for it will be copied. Wblock/Insert is used when the user keys in ^C and ^V.

Mass Haul View

Views are automatically named according to “Existing Name” (#), where # is an increment. If a conflict is found, the next counter will be used.

The copy command or right-click “Copy Selection” will create a copy of the View with a name of “Existing Name” (#), where # is an increment.

The explode command will keep the layer and display settings. Exploding the View will not explode the haul line.

The mirror command is successful on a View, but it will not honor the mirror settings. You will get an additional copy of the Profile View.

If the View is Wblocked, all objects that are required for the View will be copied. Wblock/Insert is used when the user keys in ^C and ^V

Civil Projection in Profile View and Section View

Erase will remove from view but should not remove plan object.

Explode will keep the layer and display settings.

AutoCAD Projection in Profile View and Section View

Erase will remove from view but should not remove plan object.

Explode will keep the layer and display settings.

Intersection

Explode will keep the layer and display settings.

Building Site

Explode will keep the layer and display settings.
