3D Model Transformation

Select the transformation type to convert the selected 3D Model from the coordinates of the model to the currently used coordinate system. MAGNET Field offers three transformation types:

3D Model Transformation By Matching Line

For this type of transformation, MAGNET Field performs the following operations:

Specify the start and end points of a line on the model and start and end points of the same line in the current job:

  1. Click in the Line Length field of the 3D Model panel to open the Select Object From Map dialog.

  2. In the Job Data panel, specify start and end points of the line in the job:

  3. Click the Save button to save the calculated transformation parameters between coordinates in the 3D model and the coordinate system used in the job.
3D Model Transformation By Matching Point

For this type of transformation, MAGNET Field performs the following operations:

Select an origin point on the 3D model and matching point in the job, also specify rotation angle and scale factor:

  1. Click in the Select an Origin Point field of the 3D Model panel to open the Select Object From Map dialog.

  2. In the Origin Point field of the Job Data panel, specify the same point in the current job. You can select it from the map or from the list of job points, or you can measure its coordinates by clicking (for GNSS device type) or (for optical device type).

  3. In the Rotation field enter the value of the rotation angle. Clicking the button opens the Compute Azimuth / Bearing dialog to calculate the value based on existing job points and lines.

  4. In the Scale Factor specify the value of scale factor. The value should be greater than 0.

  5. Click the Save button to save the calculated transformation parameters between coordinates in the 3D model and the coordinate system used in the job.
3D Model Transformation By Plotting Scale

For this type of transformation, MAGNET Field performs the following operations:

Select an origin point in the job, also specify rotation angle and scale factor. By default, the origin point of the model is its top left point:

  1. In the Origin Point field, specify the point in the current job. You can select it from the map or from the list of job points, or you can measure its coordinates by clicking (for GNSS device type) or (for optical device type). If you did not select an origin point from the job, the application will use a point with plane coordinates (0;0) as the origin point.

  2. In the Rotation field enter the value of the rotation angle. Clicking the button opens the Compute Azimuth / Bearing dialog to calculate the value based on existing job points and lines.

  3. In the Scale Factor specify the value of scale factor. The value should be greater than 0.

  4. Click the Save button to save the calculated transformation parameters between coordinates in the 3D model and the coordinate system used in the job.
