Support 1 and 4 doesn’t along local coordinate system, where X is along the tangent of the axis.
Of course this behavior maybe a bit surprising. But inside the database nodal results do have no direction. The support forces are always saved in the global coordinate direction. Nodal supports with unique support conditions in x an y direction (point 1= all fixed xy and point 4= all free xy) will be not displayed in our VIEWER according the local coordinate direction.
Of course GRAPHIC and RESULT VIEWER are capable to show the support reactions in the local coordinate system
Hope that helps understand what the software does.
