Changes in version 7.0-01 (21/7/10)

[+] You can choose the precision of the floating point numbers by selecting the corresponding option
in the 'Numbers' tab of the 'Options' form.
The option form is showed by executing the 'Tools->Options...' command in the plan window.

[-] Bug fixed. In some cases, errors caused in the automatic stations insertion.

Changes in version 7  (28/2/10)

[-] Bug fixed. In some cases, errors caused in plan geometry when the horizontal alignment
Poly-line had collinear HPIs.

[+] The result tables includes additional command that can be used to calculate details about
deck areas. This array includes also the length (along the road axis) of cut-slopes ditches.

[+] In the 'Stations' array of the results table, a new column including the azimuthal angle
has been added.

[+] In all tables, a menu which includes the copy/paste commands has been added (the program
shows this menu by pressing the right mouse button).

[+] You can define the clothoid (spiral) curves in horizontal alignment by using the parameter (Α)
or the length (L) or the deflection (dR) of central circular arc.
By default the program uses the parameter (A) in order to define the clothoid (spiral) transition
curves.

[+] You can define the vertical fitting curves in vertical alignment by inserting the radius (R)
or the length (L) or the parabola parameter (K).

[+] Three additional point types (120, 121, 122) are available in the TCS definition. The first
two codes correspond to the ditch bed of the left (code 120) and right (code 121) semi-section
respectively. The third code corresponds to the median ditch bed (code 122). You can define these
points in the same way as the other TCS points. The point tracks along the road axis are drawn also
in the profile drawing together with the corresponding legend. The tracks are drawn in the profile
drawing only if you include the codes 120-122 in the TCS definition. In this way you can define
additional poly-lines in the profile drawing apart from the ground-polyline and road axis (for
example you can draw the earthworks crown poly-line in hydraulic projects).

[+] The program is able to compute the pre-camber of the water in the curves of a channel.
You can enable this option by checking the 'Water super-elevations in bends' option
in the 'Hydraulics params' tab of the 'Design parameters' form.

[+] DIOLKOS is able to compute complex hydraulic cross-sections.
The program splits the cross-section into separate parts and computes the hydraulic parameters
for each part. The total water supply of the cross section is equal with the sum of the water
supply that corresponds to each part. The boundary points of each part are defined in the Typical
Cross Section (TCS) of the project. These boundary points have code 130.

[+] The profile, diagrams and cross-sections drawings are full parameterized.
If you press the 'More' button in the 'Drawing parameters' form, the program shows the 'Drawing
preferences' form. This form includes six tabs. The first four tabs are related with the profile,
diagrams and cross-sections drawings.
In these tabs, you can define:
a) The line and poly-line entities included in each drawing.
b) The legend rows and the order in which are appeared.
c) In the profile and cross-sections drawings you can define the ratio dx/dy (in the previous versions
this ratio was equal to 10/1 for the profile drawing and 1/1 for the cross-sections drawing)
In fifth tab you can define the title of each row in the legend.
In the sixth tab you can modify the layer names and the corresponding colours.
If you press the 'Save as default' button the current configuration is saved as default.
If you press the 'Load default' button the initial configuration of the program is loaded.

[+] The program includes a new diagram modification tool. This tool is showed when you execute
the 'Command->Modify diagram vertex' command of the Diagrams window. This tool is showed also
by double clicking in the Diagrams window. By clicking near to a vertex, the program shows a
form with which you can move or delete a specific vertex. This tool can be used to modify the
super-elevation rate, widenings and drainage layer diagrams when one of these is visible in
the Diagrams window.
You can import in a curve different super-elevation value from the value assigned by default.
In order to do this, you must execute a double click near to the chainage of the curve.
When you insert the new value the program updates the super-elevation rate diagram in the
specific curve accordingly.

[+] Extra tool in plan window shifts a tangent of the horizontal alignment parallel to its
initial direction.

[+] Extra tool in profile window shifts a tangent of the vertical alignment parallel to its
initial direction. Additionally, the 'Move vertex' command is also added in the profile
window. This command operates in the same way as the corresponding command of the plan window.

[+] The 'Terrain mesh generator' form of the plan window is replaced by the 'Terrain-Background builder'
form. In this form you can define the terrain model and the background drawing by using a DXF file.

[+] The commands for the online insertion (from AutoCAD) of the terrain and background drawings
are moved in a separate menu.

[+] In the typical cross-section library you can import the thickness of each layer for the
predefined TCSs.

[+] Improved reading/writing speed from/to DXF files.

[-] The commands for the creation of GRD, TIN and TRI files have been removed from the file menu.

[-] The commands used for the creation of help points by the deck have been removed from the 'Help
Points' forms of Plan and Profile windows.

[+] The 'Design parameters' form is moved from the 'Edit' menu of the Plan window to the 'Insert'
menu.

[+] The program includes a new widenings insertion tool.The program inserts the widening via a
form in which you must define the middle point of the chainage range, the widening value, the
length of the widening, the length of transition curves in entrance and exit as well as the fill-out
length of the transition curves (the form has a relative figure describing all these variables).
The widening can be applied anywhere along the road axis without any restriction.
You can apply the widening on the left or on the right boundary line by using the 'Widening edge'
radio button. If you want to insert widening on both boundary lines you must insert widening
twice (one for the left boundary line and one for the right). If you want to apply widening on
a specific vertex of the horizontal alignment, you must select the desirable vertex in the
'Select Hpoly Vertex' combo box. In this case, the program will set the length of the widening
equal with the length of the arc and the length of transition curves in entrance and exit equal
with the length of the corresponding clothoid curves of the selected vertex. Note that the program
applies the widenings on the widenings diagram of the current road.
The program will update the sections accordingly if you press the "Update sections" button
in the 'Widenings diagram table' form.

[-] The 'Correction' command button placed on the Super-elevation table has been removed.
You can adjust the super-elevation rate diagram by using the new diagram modification tool.
 

Changes in version 6.5-05 (10/9/09)

[+] Improvement of approximate method in hydraulic calculations.

[+] Results extraction (text and arrays) in files with RTF format
(for reading with MS Word) and in CSV format (for reading with MS Excel).

[-] User interface improvement. The units are not presented in some input fields.

[+] The program is able to project an image on the terrain model. The image is projected
on the faces of the terrain model. The position and orientation of the image is defined in the
'Image projection' form. This form is showed by executing the
'Insert->Terrain model->Image projection...' command of the plan window.
In this form you can define the upper left and the upper right coordinates (in the current
coordinate system) together with the height of the applied image.
 

Changes in version 6.5-04 (27/5/09)

[+] DIOLKOS support the OpenGL graphics acceleration engine.
Switch between OpenGL and Direct3D by changing the selection in the 'Tools->Options...' form

[-] Fixed User interface. When we 'click' on the first or last vertex of horizontal alignment the program
does not present the R,A insertion form.

[+] The program produces the drawing for the V85 diagram.
DIOLKOS is able to draw the V85 diagram when we have computed the V85 diagram in the 'Diagrams' window.
The drawing is produced by executing the 'Results->Drawings->V85 diagram" command

Complete design tools for sight checks along the road axis.
Sight study (stopping sight distance, passing sight distance) with real time report durring the virtual 3d animation
and drawing production for the stopping and passing sight distance diagrams.

[+] Sight diagram calculation
The parameters (driver and obstacle distances from axis, obstacle height, eye height form deck)
are imported in the 'Diagrams' tab of the 'Design parameters' form.
The sight diagram is computed by executing the 'Command->Compute visibility diagram' in the 'Diagrams' window.
We can compute the stopping or passing sight distance by having the obstacle distance from the road axis
with positive and negative value respectively.
We can produce the drawing for the current computed sight diagram by executing the
'Results->Drawings->Visibility diagram' command.

[+] Real time check the current sight distance from the driver's position along the road axis.
To enable this feature we must check the 'Max visible position' in the '3D view' form
(This form is appeared by executing the View->3D Parameters... command) and then
we must execute the 'View->3D Animation' command.

[+] Determination of the horizontal sight distance envelop curves.
These curves are computed in the Plan window by executing the 'Plan->Compute sight envelop curve'
command. The parameters for the computation are taken from the 'Diagrams' tab of the 'Design parameters' form.

[-] Bug fixed. The ROA files are recognized by Windows as the essential file type
of DIOLKOS software thus we can open them with double click.

[-] In the 'Sections' window the navigation toolbar buttons are updated with new icons.

Changes in version 6.5-03 (14/3/09))

[-] Bug fixed in manual modification of section poly-lines.
The program ignored mouse clicks when these fell in the yellow square.

[-] Bug fixed in section convex-hull calculation when in special design cases additional
section layers must be inserted (manually) in some cross-sections.

[+] Full copy / paste functionality with ctrl+C / ctrl+V key strokes between all Diolkos
arrays as well as between Diolkos arrays and Excel.

[+] In the swept-paths form a button for direct drawing production of the swept-paths
poly-lines was added.The drawing is exported directly to AutoCAD or to a DXF file depending
on the choice selected in the 'Drawings parameters' dialog box (Drawings output).

[+] The settings in the Swept-paths form are saved in the RΟΑ file.
The restriction for the calculation in chainage range with length < 500 m was removed.
Also, the program shows a progress bar describing the calculation status.

[+] The UNDO/REDO functions are available also in the quantity survey commands.

[+] Analysis of stonework and insulation quantities in the culvert quantities measurement.

[+] The program draws the current chainage line also in the profile and diagrams windows.
This option can be enabled in the 'Layers' dialog box of the plan window.
Attention is needed because this option may slow down the drawing commands in the profile window.

[+] The plan window has its own help points.

[+] The cross-sections can be temporary moved left or right from its original position by using
the "Ν" and "Μ" keys respectively. The program can update the plan help points from cross sections
exactly like the profile help points can be updated when the cross-sections have been moved up or
down from its original position using the "+" and "-" keys respectively.

[+] A tool displaying warnings during the design time is available (warnings examples: 'Terrain
data has not been inserted' etc.). This tool was added in the 'Geometry check' form. When the program
has a warning to show the toolbar at the down side of the window displays a orange colored 'W' symbol
(now the program displays in this position a green 'ΟΚ' or a red 'ΕR' symbol).
Also the button 'Clear' from the 'Geometry check' form was removed.

[-] Bug fixed in the depiction of existing road in the cross-sections window when the fill graphics
button is pressed.

[-] The 'Help points' terminology has been definitized. The term "Control points" is not used anymore.
Now the program has four types of help points :
a) Help points in the Plan window
b) Help points in the Profile window
c) Help points (construction) - Used when you want to measure quantites during the construction stage.
d) TCS Help points - Used in the Typical Cross Section (TCS) definition.

[+] In the 'Terrain mesh generator' form a checkbox relatively with background drawing is added. When this
checkboxis selected the program insert the current selected DXF file and as background drawing.
Thus, we can calculate the terrain model and define the background drawing with one action.
The 'Terrain mesh generator' form is showed by executing the 'Insert->Terrain model->Terrain mesh generator...'
command on the plan window.

[+] When a vertex is moved in the Plan window, the program shows the two different placement options with
two colors. White for the option of positioning the vertex on mouse cursor and orange for the option of
positioning the vertex on the horizontal alignment poly-line.


[+] In the 'Tools' menu of the Plan window a new command for the forest road design has been added.
When this command is executed the program is prepared to design a forest road.
This command can be executed any time during the design time.




Changes in version 6.5-02 (8/2/2009)

[-] Bug fixed in the UNDO/REDO toolbar.

[+] Characteristic stations (Ε,Ε') inserted also and in the middle of the clothoid curves.

[+] Improved drawing production speed.

[+] Osnap capability in all windows. This function is enabled or disabled by pressing the F3 button.

[+] Change the modification step while move a cross-section manually to a new position.
By pressing the F2 key the modification step changes from 0.01m to 0.1m and vice versa.

[+] When a background layer has name with more than one words, the program combine all words to one
using the underscore ('_') character.

[+] When we insert TCSs from the library the program give the option to keep the existing TCSs of the
current project.

[-] Bug fixed. When the TIN lines was drawn in DXF file the lines did not have elevation.

[-] Bug fixed. If the *.gr file did not contain terrain data for a station the program
presented error message while loading the ROA file.
