Stake Out Alignments
Figure 18
Now, tap “
New Section
” and change the new section
type to create another transition curve, now joining
the arc and a straight:
Figure 19
The spiral is already set to “
Curve to Tangent transition
”
type, starting with curvature radius of 150 m and end-
ing with zero curvature. We only have to change the
length to 50 m and finally add another straight line
100 m long, supplying our horizontal alignment with
the fifth section (not counting the starting point).
Note: the “
Close
” (
) button can be used to add a
straight section towards the starting point if it is
necessary to design a closed figure (e.g. fence). This
button is displayed only for the last section, and only
when distance between starting point and endpoint
of the last section (mis-closure) is larger than Min.
Stakes Distance (see Staking chapter). Pressing the
button brings up a confirmation dialog indicating
current mis-closure.
Let us see what we have constructed: tap the “
Pre-
view
” button. You should see something like shown in
Small red circles represent design points to be gener-
ated. As each newly created alignment inherits stake
generation options from previous one (more strict-
ly speaking, each time the generation options are
changed, they are saved as default values for future
alignments), the spacing between the stakes may be
different depending on what had been done on this
device before..
