Analysis View

Used to display analysis effective lines of selected structural objects. It is possible to modify the effective lines manually by using the offered options of this function or by modifying them via handles.

Analysis display allows you to control and work on the effective static analysis lines of the shapes to get an optimum output for translation to static analysis programs. From the individual interfaces, you can force the output of analysis display. The effective lines defined by you are outputted instead of the center lines of the shapes.

If no modifications are made here, the effective lines correspond to center lines. This tool allows you to modify the effective lines independently of the insertion of a shape to balance for instance, eccentricities, if these have no importance for calculation or to close open nodes.

Check Colors at Start When checked, the colors of the represented shape ends will be verified automatically, every time the function is loaded.
Check Connections at Start When checked, the different parts will be verified automatically whether they are connected with each other or not, every time the function is loaded. Display is adapted accordingly.
Hide ... When these options s are checked, the selected objects will be hidden to provide a clearer view.

You can hide work frames, structural objects (auxiliary lines of structural object), polyplates, bolts and connecting parts such as web angles, etc.

Shorten offsets When checked, the “cantilevered” ends at a node will be shortened, so that there will be no offsets.
Use Plugin Connection When checked, the plug-in connection, when available is used.
Max Offset Used to specify the maximum possible offset in the corresponding input field Max offset. All values larger than the actual value e.g. a cantilever and will not be taken into account.
OK Closes the dialog and save your changes.
Cancel Closes the dialog without saving changes.
Help Opens online help.
Template Saves and retrieve (Using Templates) settings to be used on other projects.
Automatically connect parts using logical links When this button is clicked, the program tries to connect the effective static analysis lines automatically to create a closed system. If the effective lines are situated in a common plane, they are extended to each other and a node is symbolically represented as a ball. At the same time, the ends adopt the same colour as the center part of the line to display a closed connection. Please note, that the penetrating lines are not divided at the nodes. You can force this division later during export.
Check and rebuild color settings When this button is clicked, the program verifies whether a connection to neighbouring parts or an open end exists. The represented colour will be modified accordingly. “Red” signifies that there is an open end and “green” means that this end is connected with a neighbouring part.

The difference between this function and the function 'Automatic' is, that here the program only checks and the display is updated where as the function 'Automatic' tries to create a connection and when doing this can also modify the effective line.

Connect parts with a manual logical link If this button is clicked, the components in question are connected with each other by means of a manual link. For this purpose you have to select the components afterwards.

The main part of the manual connection keeps its position; the connected parts are related to this main part so that their effective lines can e.g. be positioned diagonally towards it. A node will be created automatically. A manual link does not have any further meaning. It only serves for creation of intended connections. On one hand, these connections are used in this function for the definition of nodes. On the other hand, they allow dimensioning of system lines at detailing.


Effective Lines

After loading the function, you first have to select the objects that are to be switched to analysis display. Having made this selection, you only see an individual line of each shape, representing the effective static analysis line. The different colours within the line help you to recognize whether the end is connected with another shape (representing a node) or whether it is open (e.g. a cantilever).

If the end is open and not a cantilever, then you are dealing with eccentric shapes in most cases and you could create a closed system by means of this function.
