Basic 2D Commands
execute an AutoCAD command, type the command (or quick-key) in the command
line. The command line is located at the bottom of the drawing area. Some
commands require additional steps, or subcommands, the next step for the
command will be displayed in the command line.
and POLYLINE – The LINE (L) and POLYLINE (PL) commands are some of the most
used commands in AutoCAD; however, each command is uniquely different than the
other. For instance, the LINE command will only draw a series of line segments.
Once the command has been completed, each segment is its own object. POLYLINES,
on the other hand, can be lines or curves. And when the command has been
completed all segments are joined together. In Microvellum, polylines are used for
a variety of commands and options. It is a good practice to use the POLYLINE
command versus the LINE command.
– The ARC (A) command will allow you to create an arc by selecting a start
point, second point, and endpoint. You can also specify a start point, center
point, and endpoint. Or, you can specify the start point and endpoint and then
enter a radius.
– The RECTANGLE (REC) command requires you to pick a base point and then pick
the opposite corner. There is an option to enter the dimensions of the
rectangle as well. If entering dimensions, a third click is required to “lock”
the placement of the rectangle as it will rotate around the base point.
– The CIRCLE (C) command requires you to pick the center point and
then specify a radius (or diameter).
– The DIMLINEAR (DD) command will create a linear dimension either horizontally
or vertically. It requires a start point, endpoint, and a point away from the
baseline for spacing the dimension. Note: DD will change the layer to the
– The DIMALIGN (DIMALI) command, will create a dimension aligned to an object
on an angle. This also requires a start point, endpoint, and a distance away
from the baseline.
– The MLEADER (MLD) command will create a leader line, based on selected
points, and open up the text interface allowing you to type a description.
– The MTEXT (MT) command will create a text box with multiple lines.
– The TEXT command will allow you to create single-line text objects.
– The MOVE (M) command will allow you to move selected objects. After selecting
the object(s), you will need to specify a base point and then specify the point
– The COPY (CO) command will allow you to copy selected objects. Like the move
command, you will need to specify a base point and point of placement.
– The ROTATE (RO) command will allow you to rotate selected objects. You will
be required to choose a base point and rotation angle (or use the reference
– The ERASE (E) command will allow you to erase selected objects. The DEL key
will also allow you to delete selected objects.
– The MIRROR (MI) command will allow you to mirror selected objects. You will
be required to choose a base point and secondary point representing the mirror
– The OFFSET (O) command will allow you to offset an object by a specified
– The TRIM (TR) command will allow you to trim (cut) lines or other 2D objects
where they may intersect another 2D object.
– The EXTEND (EX) command will allow you to extend a line, polyline, or arc to
the nearest intersection of another object.
– The SCALE (SC) command will allow you to enlarge or decrease the size of an
object based on a scale factor. You will be required to specify a base point
and factor (you may also reference a length and enter a new length).
– The STRETCH command will allow you to stretch points of an object. To stretch
points, you will be required to use the “select crossing” window to select the
points. After the points have been selected, move them in the desired direction,
and specify a distance.
– The CHAMFER (CHA) command will allow creating a bevel or chamfer between two
intersecting or adjoining lines. You will be required to specify a distance
away for each segment, or you may specify an angle.
– The FILLET (F) command will allow you to create a radius cut between
intersecting or adjoining lines. You can also use FILLET to join two
non-perpendicular lines to create a sharp corner between 2 entities if the
radius is 0.
– PICKSTYLE is a variable that can be turned on or off (1 or 0). If PICKSTYLE
is on, it will allow all objects that belong to a group to be selected. With
PICKSTYLE off, individual objects in a group can be selected. This can be
toggled quickly using CTRL + H.
OBJECTS – The ISOLATE OBJECTS (ISO) command will allow only the selected
objects to be visible. ISOLATE OBJECTS also works for 3D objects. Using this
with PICKSTYLE turned on is helpful to isolate an entire Microvellum product.
OBJECTS – The HIDE OBJECTS (HIDEO) command will allow the selected
objects to be hidden (opposite of ISOLATE OBJECTS). HIDE OBJECTS also works for
3D objects. Using this with PICKSTYLE turned on is helpful to isolate an entire
OBJECTS – The UNISOLATE OBJECTS (UNISO) command will allow you to make
all hidden objects visible.
