Continuous footing
Continuous footing drawing is done on the screen graphically by means of
mouse. Columns should be defined before single footing drawing. This is prerequisite
for single footing drawing. However, there is no such a requirement for
continuous footing drawing. Continuous footings can also be drawn alone, without the
presence of columns. This property is useful for drawing footing ties in
massive construction projects. The continuous footings in projects with columns are
connected from column to column.
The properties of continuous footings can be set before or after footing
drawing. However, it is recommended to enter Continuous Footing Settings and make the necessary changes before starting continuous footing drawing.
To draw continuous footing:
Left-click Draw/Entities/Footings/Continuous Footing.
Move the cursor on the point that the first end of the footing will be located
(it can be the node of a column) and left-click. The first node of the footing
will be generated at the point clicked (if you clicked on a column, the first
end of the footing will be connected to the column).
You may change the definition axis of the footing by pressing the space-bar
from the keyboard. The space-bar changes the choice top-bottom-middle at single
footing settings.
After determining the first point of the footing, bring the cursor on the
point that the second end of the footing will be located and left-click.
The footing will be drawn (if the quick drawing mode is inactive change the
footing ID or approve the automatically given name by pressing enter).
Press Esc to exit the mode. The single footing drawing will be completed.
As denoted above, the continuous footings usually connect columns to each
other. However, in some cases it may be necessary to make cantilever foundation
beams. Cantilever footings are foundation beams with one end at column and the
other end free. When drawing such footings, the footing length can be determined
using the co-ordinate box.
After connecting the first end of the footing by clicking on the column in the
continuous footing drawing mode, press L from the keyboard. The cursor will
get in the L cell o0n the co-ordinate box. Enter the length value (m) here and
press enter. The cell is locked to the entered value taking red color. Move the
cursor in the direction that the footing will be drawn and left-click to
determine the second end of the footing. The footing drawing will be completed. It is
possible to determine the inclination angle of the continuous footing on the
plan in the same way, this time by pressing A from the keyboard and entering the
A cell on the co-ordinate box.
