Curved 2D members (esa.02)

 

esa.02

Highlights
Easy-to-use graphical user interface.
Straight and curved 1D members, planar and curved surfaces including their intersection.
Full control of the display style including perspective, rendering, activity, colour management, etc.
Extensive library of predefined materials, cross-sections and type-structures.
Independent analysis and structural model which means both accurate results and realistic and nice looking pictures.

Graphical user interface

The graphical user interface is the “communication” link between the user and the system. Its main features are:

  • The view of the structure (i.e. zoom ratio, view direction) may be adjusted as needed, several graphical windows may be opened at the same time while the same or different parts of the structure are displayed in each of them.
  • All accessible functions are clearly sorted in a standard menu and also in a clear tree menu that guides the user through individual steps.
  • Functions that are not accessible (either due to their absence in a particular license or because some preliminary steps of the design have not been completed yet) are hidden and therefore do not add to the complexity of the menu.
  • Everything that has been defined can be displayed on the screen, including hinges, reinforcement, cross-links, stiffeners, etc., which makes it a simple task to check the work.
  • A structure constructed in steps can be easily reviewed for each construction stage.
  • The emphasis is on interactive CAD-style graphical work, so that the user can really “draw” his structure on the computer using drag-and-drop, rendering, grids and other implemented graphical tools. On the other hand, the detailed numerical input of individual values or checks is also possible if necessary (e.g. node coordinates or reinforcement schemes)

Perspective

The perspective view of the structure is a very useful tool when presenting to your customers.

Rendering / Animation

The structure is normally drawn as a line model. For presentations, however, a more attractive view is available. Several rendering modes are available to help producing effective drawings.

Curved surfaces

Not only planar, but also curved surfaces (members) can be input into the model. The structure may contain e.g. cylinders, cones, hyperboloids, spirals and other simpler or complex shapes. From a mathematical point of view all these surfaces are defined as arbitrary quadrilaterals or triangles. The shape of the edges then specifies the shape of the final surface.

Once a curved surface (member) is input, it can be edited by using standard functions for geometric manipulation. The edges can also be edited and, if required, their shape can be altered e.g. from Beziers curve to a line or vice versa.
