Instead of binding each component object handle to a plane separately, you can use magnetic construction planes and lines. The objects that are directly on a magnetic construction plane (or line) will move with the plane (or line), which means you only need to create one distance variable instead of 8, for example.
For example, create a plane that goes through all the handles and chamfers of the custom component.
Tekla Structures creates a construction plane. For example:
The plane properties are shown in the property pane.
Now when you move the construction plane, all handles that are on the plane are moved as well:
For example, the inner flange of the column:
Tekla Structures displays a distance symbol for the binding. Now if you move the part face, the handles on the magnetic construction plane will follow.
Only the objects whose reference points are directly on the magnetic construction plane are affected. By default, the magnetic distance is 0.2 mm. To change this setting, use the advanced option XS_MAGNETIC_PLANE_OFFSET.
Tekla Structures creates a construction line.
The line properties are shown in the property pane.
Now when you move the construction line, all handles that are on the line are moved as well.
Tekla Structures displays a distance symbol for the binding. Now if you move the part face, the handles on the magnetic construction line will follow.
