In CAESAR II 2017 (Version 9.0), you will notice a number of enhancements to the graphics that improve both the visual display of your model and provide increased functionality in terms of graphical-based modelling operations.
In previous versions of CAESAR II, applied displacements or applied forces and moments on a given node were displayed as in Figure 1. It was not always clear on which node the displacements/forces and moments were applied, and it was not visible on the model without activating the legend.
In CAESAR II 2017, the display of displacements/forces and moments on the 3D model has been improved to show a set of symbols similar to restraints. The software shows the resultant load as a vector arrow, as in Figure 2a, and any fixed degrees of freedom are shown as a symbol similar to the restraint symbol, with rotational directions having a new symbol to differentiate from translational directions, as shown in Figure 2b.
New enhancements also include improvements to the display of axial restraints and node numbers. In previous versions of CAESAR II, axial restraints were displayed on the centerline of the pipe at the specified node. This could often lead to the restraint being hidden and displayed inside the pipe, and users had to either switch to a translucent shade mode or increase the display size of restraints to make the axial support visible, as shown in Figure 3.
CAESAR II 2017 features an improved display of axial restraints. Axial restraints are now offset to the outside of the pipe, with a leader pointing to the pipe centerline at the actual node number, as in Figure 4. Additionally, the orientation of the axial support is dynamic, so when you orbit around the model to a different viewpoint, the axial restraint display updates to face your viewpoint. This means the axial support is always visible and is never hidden inside or behind the pipe.
The node number display has been enhanced similarly, so that when the viewpoint is changed, the node number display is also dynamically adjusted to display the node number always in front of the pipe so that node numbers are not hidden behind the pipe.
As well as the display enhancements, CAESAR II 2017 has also improved the graphical editing functionality. Using the mouse right-click, a shortcut menu is displayed in the graphics that will allow different functionality depending on what you select. For a single element selected, you have a choice of performing various operations, such as inserting, deleting, or breaking the element.
Additionally, you can insert a rigid or a restraint or edit it on the selected element. The Insert Restraint functionality has also been enhanced so you can insert an additional node in the same process.
These changes vastly improve your workflow, requiring many less operations to break an element and add a restraint.
The right-click shortcut menu is also available when multiple elements are selected, providing access to the block operations, such as duplicate, rotate, renumber, and more.
