3D COMMANDS LIST
Polysolid: You can create 3D walls with straight and
curved segments of constant height and width.
Box: Starts the box by setting the first corner.
Entering a positive value draws the height along the
positive Z axis of the current UCS. Entering a negative
value draws the height along the negative Z axis.
The base of the box is always drawn parallel to
the XY plane of the current UCS (work plane). The height
of the box is specified in the Z-axis direction. You can
enter both positive and negative values for the height.
You can create a 3D solid with POLYSOLID just as you
would a polyline. The PSOLWIDTH system variable sets
the default width for the 3D solid. The PSOLHEIGHT
system variable sets the default height. You can also
convert existing 2D objects such as lines, 2D polylines,
arcs, and circles to 3D solids with a default height, width,
and justification.
Presspull: Dynamically modifies objects by extrusion
Extrude: Creates a 3D solid from an object that
and offset.
encloses an area, or a 3D surface from an object with
open heads.
Get visual effect as you move the cursor after selecting a
2D object, an area formed by a closed boundary or a 3D
solid face. The press or pull behavior responds to the type
of object you select to create extrusions and offsets.
Objects can be extruded orthogonally from a
plane of the source object, in a specified direction, or
along a selected path. You can also specify a taper angle.
You can reshape mesh objects by smoothing, creasing,
refining, and splitting faces. You can also drag edges,
faces, and vertices, to mold the overall form.

Sphere:
Cone:

Torus:
Solid, Union: Combines two or more 3D solids,
Interfere: Creates a temporary 3D solid from the
surfaces, or 2D regions into single, composite 3D solid,
surface, or region.
interferences between two sets of selected 3D solids.
Interferences are highlighted with a temporary 3D solid
represents the intersecting volume. You can also choose
to retain the overlapping volumes.
Using the Union command with surfaces, it will
cause the surface to lose associativity. Instead, it is
recommended that you use the surface editing
commands:
Commands:
- SURFBLEND
- SURFFILLET
Pressing enter starts interference testing of pairs of 3D
solids and displays the Interference Checking dialog box.
- SURFPATCH
Extract Edges (XEDGES): Creates wireframe
geometry from the edges of a 3D solid, surface, mesh,
region, or sub object.
Slice: Creates new 3D solids and surfaces by
slicing or dividing existing objects.
The cutting plane is defined with 2 or 3 points by
specifying a major plane of the UCS, or by selecting a
planar or a surface object. One both sides of the sliced
objects can be retained.

3D solid objects can be sliced using specified
planes and surface objects

Surface objects can be sliced by specified
planes only

Meshes cannot directly be sliced or used as
slicing surfaces
Solid Intersect: Creates a 3D solid,
surface, or 2D region from overlapping solids, surfaces,
or regions.
With intersect, you can create a 3D solid from the
common volume of two or more existing 3D solids,
surfaces, or regions. If you select mesh, you can convert
it to solid or surface before completing the operation.
You can extrude 2D profiles and then intersect them to
create a complex model efficiently.
Thicken: Converts surface into a 3D solid
with a specified thickness.
A useful technique for modeling a complex 3D
curved solid is to first create a surface and then convert it
to a 3D solid by thickening it. If you select a mesh face to
thicken, you can choose to convert the mesh object to a
solid or surface before completing the operation.
o
Surfaces to thicken
Specifies one or more surfaces to thicken into
solids.
o Thickness
Sets the height of the thickened object.
3D Mirror: You can create objects that
represent half of a drawing, select them, and mirror them
across a specified line to create the other half.
3D Move: In a 3D view, displays the 3D
move gizmo to aid in moving 3D objects a specified
direction.
With the 3D move gizmo, you can move selected objects
and sub objects freely or constrain the movement to an
axis or plane.
Copy:
Copy an Object Using Two
Points
1.
Click Home tab > Modify panel > Copy.
2.
Select the objects to copy and press Enter.
3.
Specify a base point for the copy.
4.
Specify a second point.
The objects you selected are copied to a
new location determined by the distance
and direction between the first and
second points.
Trim:
If the default gizmo (DEFAULTGIZMO) is 3D Move, the 3D
Move gizmo is displayed whenever you select an object
in a view with a 3D visual style. If the visual style is set to
2D Wireframe, the visual style changes to 3D Wireframe
for the duration of the command.
The 3D Move gizmo is displayed at the center of the
selected 3D object or objects by default. The 3D Move
Gizmo shortcut menu offers options for aligning, moving,
or changing to another gizmo.

2.
Select the cutting edge for trimming (1).
3.
Enter p (Project).
4.
Enter v (View).
5.
Select the object to trim (2).
3D Align:
1.
Click Home tab
Align.
Modify panel
3D
2.
Select the objects that you want to align.
3.
Specify either one, two, or three source
points and then the corresponding first,
second, or third destination points. The
first point is called the base point.
Stretch: Objects that are partially enclosed
by a crossing window are stretched. Objects that are
completely enclosed within the crossing window, or that
are selected individually, are moved rather than
stretched. Some types of objects such as circles, ellipses,
and blocks, cannot be stretched.
The selected objects are moved from the
source point to the destination point, and
second and third points, if you specify
them, rotate, and tilt the selected objects.
3D Rotate: With the 3D Rotate gizmo, you
can drag to rotate selected objects and sub objects freely
or constrain the rotation to an axis.
Fillet: Rounds the edges of two 2D objects.
A round or fillet is an arc that is created tangent
between two 2D objects.
A fillet can be created between two objects of the same
or different object types: 2D polylines, arcs, circles,
ellipses, elliptical arcs, lines, rays, splines, and xlines.
If the visual style setting is 2D Wireframe, the visual style
changes to 3D Wireframe for the duration of the
command.
The 3D Rotate gizmo is displayed at the center of the
selected object or objects by default. You can adjust the
axis of rotation by using the shortcut menu to change the
location of the gizmo.
Erase:

Click ERASE or use the ERASE (or DELETE)
command to erase objects from a
selection set.

Select the items to erase, then press the
Delete key on your keyboard.
Once the ERASE command is active, instead of selecting
objects to erase, you can enter an option, such as L to
erase the last object drawn, P to erase the previous
selection set, or ALL to erase all objects.
3D Scale: Use this method to resize the
objects only along a plane that you specify.

3.
Click two points in the drawing to specify
the reference distance.
4.

3D
Select the objects and sub objects you
want to scale using the following
methods:

Press and hold Ctrl to select
sub objects (faces, edges, and
vertices).

Release Ctrl to select entire
objects.
When you have selected all objects, press
Enter.
The Scale gizmo is displayed at the center
of the selected object or objects.
4.
Scale: Resizes selected objects, keeping the
proportions of the objects the same.
Do one of the following:

To scale along a plane: Hover
the cursor over one of the
bars found between each of
the axes of the gizmo until it
turns yellow. Click the yellow
bar.

To scale
uniformly: Hover the
cursor over the triangular
area closest to the center
point of the gizmo until it
turns yellow. Click the
The ratio between the reference distance and the new
length determines the new size of the objects.
Offset: Creates a geometric object that is
parallel or concentric to the selected object at a specified
distance.
For example, if you offset a circle or an arc, a larger or
smaller circle or arc is created, depending on which side
you specify the offset. If you offset a polyline, the result is
a polyline that is parallel to the original.
