This task explains how to apply a transformation on surfaces using a specified number of vectors. | |
![]() |
A vector is a pair of points. The first point is the start point and the second point the end point. Only operations activated in the field Options are executed.
|
|
As example is used an aircraft door larger than the aperture must fit into. Using a specified number of vectors, the door will be adjusted from one position to its assembled position. | ||

The transformation of the geometry begins by selecting pairs of vector positions. | ||

|
The vector 'Translation' appears. | ![]() |

|
The door is now translated as a feature result. | ![]() |
|
Next we will perform a rotation of the geometry by selecting another vector. | ||
|
||
The vector 'Rotation' appears. | ![]() |
|

|
The door is now rotated. | ![]() |
|
Next we will perform a scaling of the geometry by selecting another vector. | ||
|
||
The vector 'Rotation' appears, representing the scaling. | ![]() |

|
The door is now scaled. | ![]() |
|
Next we select the remaining pairs of points to perform a compensation of the geometry which will fit it exactly into the aperture. | ![]() |
|
|
![]() |
|
The door is now adjusted to its final position. | ![]() |
|
The result of the Adjust operation is a feature result. |

You can define the following options:
|
|||||||||||||||||
The options Translation and Rotation have to be switched on if you want
Scale and/or Compensation. If you select additional points, the vectors 'Translation', 'Rotation' (and 'Scale') work as well-known. From the additional points a start plane (mean plane from the start points) and an end plane (mean plane from the end points) is calculated. The geometry is transformed from the start plane to the end plane. |
