Transform drawing in survey

Transform drawing in survey transforms selected drawing objects in survey objects and creates new topographic points in the main positions.

The main difference is that a survey line is connected to topographic points: if the topographic points undergo a transformation or in general move, the line follows the points.

• Click Survey.

• Click Tools to open the menu.

  

• Click Transform drawing in survey.

• The command opens a new panel.

  

• In Settings it is possible to define the parameters for the transformation:

  • Add points: to enable/disable the creation of topographic point on the drawing main position. The command checks if the drawing entity corresponds to existing topographic points. Basically it checks if a point already exists at the end of a drawing line. If it doesn't exist it is created, if it does the resulting relief line is snapped to that point.

  • Next point name: if Add points is enabled, this field is used to define the point names.

  • Check 3D positions: enables the verification if a topographic point exists before creating it in 3D and not only in 2D.

  • Use point’s elevation: the elevation of the topographic point is calculated from the drawing.

  • Survey code mode: select how to define the survey code of created points:

    • No code: no survey code is used.

    • Use default code: to assign to all points the same survey code, that is defined in Survey code field.

    • Use layer name: to assign to points the survey code taken from the drawing layer name.

• In Data to tansformation it is defined the source data and destination for the drawing data to transform:

  • Select objects from CAD: to enable/disable the selection of drawing data graphically from CAD.

  • Select objects from document: to transform all data from selected Drawing subproject.

  • Drawing: if Select objects from document is enabled, select here the Drawing subproject.

  • Survey: the Survey subproject where the transformed data is created.
