You have several options now:

  • Auto scale: If this option is enabled, OCAD takes a scale which fits best to the dialog box.
  • Scale: Choose the desired scale of the profile in the dropdown list.
  • Show grid: If this box is activated, a grid is shown in the profile.
  • Elevation factor: Choose an elevation factor in the dropdown list. This is the scale factor for the horizontal profile axis (height).
  • The Elevation resolution and the Length resolution are filters that influence the calculation of the total ascent and total descent. These resolution values should not be more accurate than the elevation resolution and cell size of the DEM.

hint DEM Profile dialog is a non-modal dialog. The user can switch to the OCAD map window. It is possible to edit the selected line object in the OCAD map. Click the Update button in the DEM Profile dialog to see the profile for the edited or newly selected object.

In the Units and Formats category, you can choose, whether the distance is to be shown in km or in m. In addition, you can set the time format (at the moment only h:mm is available) and the rounding (no rounding, 5 minutes, 10 minutes). Uncheck the Show text at the bottom of the profile option if you do not want any text under the profile.

In the Labels and Symbols category, labels and symbols can be allocated to the start- and endpoint or a stopover. Enter a label in the corresponding field (for example the name of a place) and choose a symbol from the dropdown list. These symbols are defined in the template file.

Click the OK button when finished. In the next dialog you have to save the profile at the desired location. To open the document, use the Open Recently Exported Documents function in the File menu. The profile can be edited (e.g. change colors or add objects) there.
