Week 4 Challenge

1. Create a terrain model by different methods –

    1. By Graphical Filter
    2. By text interpolation
    3. By elements

2. Edit the terrain model created

3. Annotate the contours with labels

4. Change the contour interval.

1. Create a terrain model by different methods –

    1. By Graphical Filter
    2. By text interpolation
    3. By elements
  1. By Graphical Filter:
  • Create new3D seed file by naming "terrain by graphical filter"
  • Click on terrain filter manager
  • Create new filter group and filters
  • Give name for filter is spot and breaklines
  • First set for spot,click on the edit filter
  • Add the levels as fallows which is given by the company
  • Click finish
  • Next do same procedure for breakline
  • Add spotfilter to the terrain filter group
  • click on finish
  • Go graphical filter select edge method as remove silver, feature definition,existing triangles

2.By text interpolation

  • Create new 3D seed file and set the name terrain by text interpolution, click save to open file
  • Go to home tabe, click on reference select the 3D survey graphics with interactive attachment click open,click on fit view
  • Go to terrain tab click on additional method in that click create by text interpolution
  • Click on terrain filter manager
  • Create text filter using element type as text feature type as contour
  • Create line filter using elements type line string feature type as contour
  • Create new filter group as line filter only

3.By elements:

  • Open a new file with 3D seedfile,give a name by element,click on save
  • Go to home tab click on attach tools and click on referances
  • Select 3D survey graphics with interactive attachment method
  • Click open and set the details as fallows
  • Click on fit view to view the file
  • Go to terrain tab click on from element
  • Set feature type as spot
  • Set edge method as remove silvers
  • Feature defintion as existing triangles
  • Go to home tab and click on level display
  • Click on the reference file
  • Do right click and click on all off
  • Select layer 38 which is spots
  • Go to element selection by layer and click on line to select all spots
  • We can see 18281 spots got selected
  • Right click to reset
  • The resulting traingles are as follows

2. Edit the terrain model created

  • To edit the terrain TIN network
  • Editing is the terrain model is to remove the spots which are at unusual elevation which create unnecessary triangles and surface
  • Create a new 3D seed file, give name as terrain editing model click on save
  • Go to terrain tab click on attach tools, click on references select attach reference
  • Select the created file
  • Select the terrain by graphical method which is created previous click on open, click on fit view to view
  • Use various options and delete unwanted spots and triangle
  • 1.Remove spot:Hover over the spots untile a wight spot is visible and click tp delete
  • 2.Delete edge traingle: Hover over terrain, unwanted edge triangle is highleted and click to delete
  • 3.Swap triangle side: Select the traingle side to swap
  • 4.Add vertex: hover over the area where a new vertex is needed and select the spot
  • 5.Move vertex canbe used to move the vertex
  • 6.Delete triangle line is used to delete the unwanted lines of terrain created using a line drawn a specific driection
  • 7.After removing all the unwanted spot and traingle the terrain model is as fallows

3. Annotate the contours with labels

  • To annotate the contours with lables
  • countors can be labled along given line in open roads using"labeling terrain contours" in terrain tab
  • Open a terrain model which is created
  • Double click on the terrain model, click on properties
  • Click turn on on major and minor contours on
  • Go to terrain tab click on label terrain contours
  • Set all following data, select the terrain model
  • Select annotating mode all contours
  • Text alignment as follow line
  • Dimension style as"label pin alignment name"

4. Change the contour interval.

  • To change the contors interval
  • Open the edited terrain model created above
  • Double click on the terrain model to view properties of the terrain
  • Click on properties
  • Click on terrain model ET
  • Select the calculated features
  • Click on contours
  • Click on the major contours
  • Give the major interval as '20'
  • Click on the minor contours
  • Give the minor interval as '5'
