Part 1: AutoCAD Basics
The other options displayed in the command
line while creating the pyramid are same as in
the Cone tool.
Move the pointer in the Y-direction and
enter 150 as the wall length.
Move the pointer in –X-direction and enter
100 as the wall length.
Select the Close option from the command
line; the wall will be closed.
Using the Polysolid tool
The Polysolid tool is used to create a 3D wall. It can
also be used to convert a line, polyline, arc, or a
circle to a wall. The Polysolid tool is similar to
Polyline tool except that you create a rectangular
shaped wall that has a pre-defined height and
width.
Click Home > Modeling > Polysolid
on the ribbon; the message, “Specify start
point or [Object/Height/Width/Justify]
:” appears in the command line.
Activate the Ortho Mode on the status bar.
Pick an arbitrary point in the graphics
window and move the pointer in the X-
direction.
Type 200 in the command line and press
ENTER; a 3D wall of 200 length is created.
Select the Arc option from the command
line and move the pointer in the Y-direction.
Type 100 as the arc diameter and press
ENTER.
Select the Line option from the command
line and move the pointer in the –Xdirection.
Type 100 and press ENTER.
Using the Extrude tool
The Extrude tool is used to add a third
dimension (height) to an existing 2D shape.
If you extrude a closed shape such as circle and
closed polylines, a solid is created. If you extrude an
open sketch such as lines and arcs, a surface is
created.
Example 1:
Start a new AutoCAD file in 3D Modeling
workspace.
Click Home > View > 3D Navigation >
Front on the ribbon; the front view will
become parallel to the screen.
