Section for Slope, Georock and the other GeoStru programs

Menu Geostru › DrawSection › Export... (macro DrawSection.esporta) writes the last section drawn to a text file with the .edp extension:

12
0
412.5
18.42
415
...

First line: number of points; then, for each point, the chainage and the elevation (one per line, point as decimal separator).

  • Build 2026.1 and later: the Save as dialog opens, proposing the drawing folder and the name <drawing>.edp.
  • Older releases: the file is always written to C:\cross_section.edp without asking. On Windows 10/11 the root of C:\ is protected: if the file does not appear, run AutoCAD as administrator or update to build 2026.1.

The file is imported in Slope (Topographic profile › Import), Georock 2D/3D, MRE, SPW and the other GeoStru programs that import a profile from a file of distance/elevation pairs.

Export right away

Only the last section drawn stays in memory: export before drawing another one and before closing AutoCAD.

Basin for Hydrologic Risk

Menu Geostru › Hydrologic Risk › Export Basin (macro Hydrologic_Risk.Bacino).

  1. At the Select a closed polyline prompt select the basin boundary: it must be a closed 3D polyline (selecting anything else gives The selection is not a 3D polyline).
  2. The program writes a text file with:
    • a "B",n,X,Y,Z line for each vertex of the boundary;
    • a "VQ",n,X,Y,Z line for each point entity (POINT) of the drawing that lies inside the basin (DTM spot heights); the points used are coloured red, like the boundary.
  3. Build 2026.1: Save as dialog (proposed <drawing>_contour.txt); older releases: fixed file C:\river_basin_contour.txt.

The file is imported in Hydrologic Risk as the basin boundary and spot heights.
