The program I use for my CAD work is
IMSI's TurboCAD V11.2
Professional. This program not only excels in drawing in 2D (two dimensional
drawing where "x" represents left and right and "y" represents up
and down) but equally excels in 3 D (where a third dimension "z" is
thrown in). For examples of 3D CAD drawing, check my main website
at:
Digital Reality With CAD where you can find numerous examples
of "rendered" 3D drawings. Rendered 3D drawings (referred to as models
by CAD users) can very closely approximate photo quality imaging.
In addition to the actual drawing of the model, the CAD user can skillfully
apply colors, textures and lighting effects to the drawn model which
can fool the viewer into thinking they are looking at an actual photograph.
I'm not claiming my renders are indistinguishable from actual photos
but I do think some of them come mightly close.
There are over 250
seperate drawing tools available in TurboCAD and most come into play
at some point if several different projects are undertaken. Can TurboCAD
draw three dimensional farm maps? Yes, it can represent mountains
and valleys along with surface objects such as buildings, trees and
other structures. Drawing three dimensional maps is only something
I have experimented with on a small scale and doing so on something
as large as a 3000 acre farm in the hills is a project I wouldn't
care to tackle due to the time required and the cost of doing so for
a client.
Below is a screen capture of TurboCAD's desktop along with
a small slice of a farm mapping project I am working on. Notice all
the little small buttons to the left side of the screen. Many of them
are "fly out" buttons where if the mouse cursor is placed on one of
them and the right click button is depressed and held, a fly out bar
will appear with numerous other drawing tools on it which can be selected.
After looking over the drawing screen, scroll on down below for some
more interesting bits of information about CAD drawing.
