Stratis

Stratis is a program system for road construction and civil engineering by the company RIB Software AG, Germany).

For export of data from STRATIS and subsequently import into CadnaA the specific exchange format CST is available for the following objects:

in STRATIS in CadnaA
object export format import format
roads CST Stratis
contour lines CST Stratis
lines of dams and embankments CST Stratis
built-up areas CST Stratis

The following features have been added to the Stratis-import filter:

  • import of the roads axis as auxiliary polygons (if existent),
  • automatic import of defined areas,
  • considers an entered additional width right/left,
  • considers asymmetrical cross-sections and lateral slopes,
  • import object designation as defined in Stratis.

Example

Path: Examples\Import\Stratis\Sca_hl.cna & S1.sca

Note

For better understanding open the example file Sca_hl.cna in CadnaA and import the file S1.sca via menu File|Import, file format „STRATIS“.

After a STRATIS file with road axis and embankment has been imported within a CadnaA project with an existing terrain model. It had been necessary to delete the existing contour lines between road and embankment base line „by hand“. This procedure is now automated to some extent.

Example: terrain model with imported road and embankment base line from Stratis

When importing in CadnaA a closed auxiliary polygon is automatically laid over the imported embankment base line of the road. If you open its edit dialog with a double-click you can look up the identifier „STRASSENRAUM” in the ID box.

Close the edit dialog again and open with the right mouse key the context menu of this auxiliary polygon.

  • Click on the command Break Lines.
  • again, from the context menu of the auxiliary polygon, select the command Modify Objects.
  • Select on the dialog the action „Delete“ with the options „inside“ and „on border“ of the polygon for the object type „Contour Lines“.

Settings on dialog Modify Objects selected from the context menu of the auxiliary polygon

  • After confirming with OK click on the button „All“ in the next dialog.

After deleting the contour lines between road and embankment base line.

Now all contour lines are deleted including the embankment base line.

  • Afterwards also delete the auxiliary polygon and the road.
  • Then, import the road again.

The slope‘s edge and the road axis are now, both, laying in the space sector being cleaned from terrain contours.
