3D Model Transformation
Select the transformation type to convert the selected 3D Model from the coordinates of the model to the job's current coordinate system. MAGNET Field offers three transformation types:
- By Matching Line - you select a common line on the model and in the current job to transform the model coordinates to the job's current coordinate system.
- By Matching Point - you select a common point on the model and in the current job to transform the model coordinates to the job's current coordinate system. Additionally, you enter rotate angle and scale values for the model. Note that rotation can be done using azimuthal angle only.
- By Plotting Scale - you select a current job's point as an origin point for model rotation. Additionally, you enter rotate angle and scale values for the model. Note that rotation can be done using azimuthal angle only. In this case, the application will rotate the model relatively to the top left point of the model.
3D Model Transformation By Matching Line
For this type of transformation, MAGNET Field performs the following operations:
- rotates the model around an origin point, the rotation angle is an azimuth of the job's line;
- scales the model; the scale factor is calculated as ratio of line length of the job to line length on the model.
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.
-
Click
in the Line Length field of the 3D Model panel to open the Select Object From Map dialog.
- Select the start point of the line on the model:
- Click on an element of 3D model to select it and display its lines.
- Then click on an intersection of lines to define the required start point.
- The orange dot confirms the start point selection.
- Select the end point of the line on the model:
- Click on an element of 3D model to select it and display its lines.
- Then click on an intersection of lines to define the required end point.
- The second orange dot confirms the end point selection.
- Click
to save the selection. The Select Object From Map dialog is closed and the Line Length field displays the length of the selected line.
-
In the Job Data panel, specify the start and end points of job's line:
- Start Point. The start point of the job is used as the origin point of the transformation. You can select the start point from the map
or from the list
of the job points, or you can measure its coordinates by clicking
(for GNSS device type) or
(for optical device type).
- End Point. The end point can be set in the same way: by selecting from the map, from the list of job points, and by measuring its coordinates. Alternatively, the end point can be also specified by clicking the switchable End Point button and choosing and entering Line Length and Azimuth values.
- Click the Save button to save the calculated transformation parameters between model coordinates and job's coordinate system.
3D Model Transformation By Matching Point
For this type of transformation, MAGNET Field performs the following operations:
- rotates the model around an origin point, the user can specify the rotation angle;
- scales the model; the user can specify the scale factor.
Select an origin point and specify rotation angle and scale factor:
- Click
in the Select an Origin Point field of the 3D Model panel to open the Select Object From Map dialog.
- Select the point of the model to use it as the origin point of the transformation:
- Click on an element of 3D model to select it and display its lines.
- Then click on an intersection of lines to define the required origin point.
- The orange dot confirms the origin point selection.
- Click
to save the selection. The Select Object From Map dialog is closed and the Select an Origin Point field displays "Point Selected".
- In the Origin Point field of the Job Data panel, specify the point in a current job. The point of the job is used as the origin point of the transformation. You can select it from the map
or from the list
of the job points, or you can measure its coordinates by clicking
(for GNSS device type) or
(for optical device type).
- In the Rotation field enter the value of the rotation angle.
- In the Scale Factor specify the value of scale factor. The value should be greater than 0.
- Click the Save button to save the calculated transformation parameters between model coordinates and job's coordinate system.
3D Model Transformation By Plotting Scale
For this type of transformation, MAGNET Field performs the following operations:
- rotates the model around an origin point, the user can specify the rotation angle (azimuthal only);
- scales the model; the user can specify the scale factor.
Select an origin point in the job and specify rotation angle and scale factor. By default, the origin point of the model is its top left point:
- In the Origin Point field, specify the point in a current job. You can select it from the map
or from the list
of the 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.
- In the Rotation field enter the value of the rotation angle (azimuthal only).
- In the Scale Factor specify the value of scale factor. The value should be greater than 0.
- Click the Save button to save the calculated transformation parameters between model coordinates and job's coordinate system.
