How to begin?
- Run an instance of Mod3D application. At the beginning two views of an empty document are opened automatically, map view and profile view. If you closed previously opened document select from menu File \ New.
-
Now choose between two possibilities how to create observations.
- If you want to create planar observation area, select from menu Model \ Define Observations and enter coordinates to Define Observation dialog. See also Mod3D Coordinate system.
- Second way is to import Digital Elevation Model (DEM) grid. Choose from menu Model \ Import Observation. You will be asked to set the vertical range. Within this range a model can be defined, and it is also used for scaling views to fit the window. You can change vertical range later in menu Model \ Change Vertical Range.
-
Open new Profile View window. Choose from menu Window
\ New Profile Window. Or use shortcut toolbar button
.
-
Use Model toolbar buttons
or
keyboard arrows keys to move across the observation area. Move to the
profile, where you would like to create a body (i.e. to the middle of the
observation area). To create new body click right mouse
button at the position where you want to insert new
body. This will open floating menu. From floating menu choose
Insert New Body. In Body Properties property page,
set the physical properties, drawing parameters of the body and description.
The body is created. Cursor will change to
if the vertex is movable. Now the body can be modified after clicking on the
vertex, hold left mouse button down and
move mouse in vertical direction. Body can be extended to the sides after the
cursor changes to 
on
the vertical body edge to . Then hold left mouse button
down and move mouse to
the side (at the beginning of body creation you MUST
move to the right).
- The simpliest way how to extend the body to the next profile follows. Click the right mouse button inside the body. From the floating menu choose Copy to Next Profile or Copy to Previous profile. The system will copy the body to the next or previous profile respectivelly.
- Move to the next profile using model toolbar buttons ad reshape the body.
-
Finally compute the field using command from menu Compute \
Compute. Or use shortcut button
from main tooldbar .
