Reversing the orientation of an entity

Each entity has got its starting point and end point. These points for example define the orientation of the local X-axis of a 1D member. If necessary, the user may reverse the orientation by swapping the end-nodes.

The procedure to reverse the orientation of a 1D member

1. Start function Reverse orientation:

   1. either call menu function Modify > Reverse orientation,

   2. or click button [Reverse orientation] () on toolbar Geometrical manipulations,

2. Select the entities that should be reverted.

3. Press [Esc] to end the function.

The alternative procedure to reverse the orientation of a 1D member

As with some other geometry manipulation functions, it is possible to swap the first two steps.

1. First, you make the selection.

2. Second, you start the function.

The function is immediately performed and automatically closed.

Note: The change of 1D member orientation can be easily verified when local co-ordinate system of the edited entity is displayed. The direction of the local X-axis inverts once the function is finished.
