Stream Survey Example

To follow this example, have the Mapping and Drafting, Surface Generation and Contouring, Profile Window and Profile Window Drafting and Design function groups enabled.

  1. FileNew. <Terrain>\Profile\topograph.terx. This is the same example used in the previous exercise, refer to figure at start of the previous section.

  1. Select the thick blue feature (Stream-2) by clicking on it with the selection cursor .

  2. View | New Window |Profile from dropdown list to view this feature in a Profile window.

Note: Editing a feature with Auto Scale set is confusing, because after each edit the screen redraws at a new scale.

Turn off auto-scaling by doing either of the following:

  1. Profile tab | Window group | Profile Options button. Opens the Profile Window Options dialogue box. De-select Auto Scale and set the horizontal and vertical scales. Press OK.

  2. Press the zoom button ; you will be prompted “OK to turn off auto-scale?” Choose OK.

  3. Zoom and scroll to center the stream profile.

  4. Right-click in the Profile window and choose mode Edit/Insert Points with mouse .

Add a point at the end of the feature:

  1. Click to the right of the last point on right; respond OK to the warning.

  2. Move your mouse around observing the captured point and connecting segment.

  3. Click a second time to anchor the new point.

Edit an existing point:

  1. Move your mouse over one of the vertex points in the feature, note that the mouse changes to the edit cursor . (The first point of a fence feature, however, is not editable.)

  2. Click on a vertex and capture the point.

  3. Move your mouse around observing the captured point and connecting segments.

  4. Left-click again to anchor the point in a new position.

  5. View | Tile Vertically button to show Profile and Plan windows side by side as in the previous exercise.

  6. Because you have just modified one of the features in the model, your contours will be out of date. Terrain Modelling | Generate TIN.

  7. Press OK to re-calculate with the previous settings.

  8. File | New. Do not save the changes.
