Grid of points

• Grid of points command creates a regular grid of points and lines based on the parameters defined.

• A selected polyline define the boundary within creates the grid; advanced parameters allow to define border area excluded from the calculation.

• Residual space at the extremities can be distributed in different ways.

• Number of points, length of lines and other values are reported as statistical information.

• Open the COGO page.

• Select Grid of points.

  

• Select from CAD view the boundary polyline.

• The software allows to enter different parameters to define the grid.

Starting point

• The Starting point parameters define the starting point for the grid.

  

  • E: east coordinate of the starting point.

  • N: north coordinate of the starting point.

  • Z: elevation of the starting point.

  • Δ: step to increase/decrease the coordinate when clicking and .

• Tap on a topographic point in CAD to select the starting point, or enter manually the starting point.

Direction

• The Direction parameter define the main direction of the grid.

  

  • Direction: the main direction angle of the grid.

  • Δ: step to increase/decrease the coordinate when clicking and .

• Tap on two topographic point in CAD to select the direction, for example two topographic points on the boundary, or enter manually the direction angle.

Layout

• The Layout parameters define the grid layout.

  

  • Single lines: the grid layout is single lines. Points are along lines.

    

  • Grid: the grid layout is a grid with main and secondary lines.

    

  • Add lines: if the layout is Single lines, creates the lines.

  • Add main lines: if the layout is Grid, creates the main lines.

  • Add secondary lines: if the layout is Grid, creates the secondary lines.

  • Add points: creates the topographic points.

Grid settings

• The Grid settings page is available if Layout is Grid.

• These parameter define the settings of the grid.

  

  • External margin: defines an external margin between the grid and the boundary.

  • Main distance: the distance on grid main direction between the points.

  • Secondary distance: the distance on grid secondary direction between the points.

  • Extend to bound: extends the grid to the boundaries.

Single line settings

• The Single line settings page is available if Layout is Single line.

• These parameter define the settings of the parallel lines.

  

  • External margin: defines an external margin between the grid and the boundary.

  • Lines distance: the distance between the lines.

  • Points distance: the distance between the points along the lines.

  • Extend to bound: extends the grid to the boundaries.

  • Residual distribution mode: defines how the residual is distributed along a line. For example if the line is long 55 meters, and the points distance is 10 meter, I will have 5 meter residual.

    • Do not distribute it: the residual is not distributed. Creates a point at the end of the line.

    • Distribute at the extremities of the line: the residual is distributed at the beginning and end of the line.

    • Distribute equally: the residual is distributed equally along the line.

    • Distribute equally adding a point: the residual is distributed equally along the line adding a point.

  • Ignore residual below: in case residuals are distributed, allows to ignore the setting if the residual is below entered value.

Results

• The Results page shows the grid creation results.

  

Save

• After parameters have been entered, press Save to save the lines and topographic points.

  • Next point name: enters the point ID of the first point in the grid.

  • Code/Layer: select the survey code where create the elements.
