QTopo - Drawing
In the QTopo drawing window you can draw scraps and save
them in therion format "th2".
In the plot window you work on a scrap at a time. When the scrap is complete
save it and erase everything to start a new scrap. QTopoShot is not a
scrap editor and assumes that you use xtherion (or another Therion
graphical program) to manage the whole cave survey.
To effectively draw your scraps stick to the following workflow:
- check in the shot table that the shot stations are correct.
You can use the 3D window and the plan and extended section windows
to visualize the centerline with the stations. The plot do not
update at the changes to the shot table; to refresh them switch on and off
the grid.
- check with the extended plot window that the shots are extended correctly.
These two steps can be done together.
- draw the plan and the extended section scrap. It is useful (but not
necessary) to follow these steps:
- select the station points;
- draw the wall lines;
- draw the other lines;
- draw the points.
- save the scraps as therion th2 file
In the plot window you can
- select the station points by clicking on the station numbers.
They are shown with a black cross
- place other Therion points. These are shown with iconic symbols,
or text (for "label" and "continuation" points). Air-draught, water-flow and
entrance can have also an orientation
- draw Therion lines (only polylines). The various line types are show
with different colors and shapes.
- display either the underlying grid or a scale bar. The grid cell size
is written in the toolbar
- display of hide the splay shots. Centerline shots are red. Splay shots
are grey
- display or hide the station names (numbers)
- select the "station" points
- insert a background image to use as sketch to follow for the drawing.
(Only if support for background images has been compiled in)
- assign and edit the shot comments
- assign and edit station comments
- modify the "extend" attribute of the shots (only extended section
plot)
