Generating Help Nodes for Dimension
Tips & Tricks
In RFEM and RSTAB, it is possible to add user‑defined dimension lines to a structural model. When creating these dimension lines, click the objects (for example end nodes of a line, members, etc.) which represent the reference points of the dimension. If you want to add a dimension line free from the structure previously defined in the model, you have to create an additional free ‘help node’ which acts as a reference object for the new dimension.
As of the program version x.06.3039 of RFEM 5 and RSTAB 8, you can generate these help nodes for the dimension directly when entering the dimensions. To create a help node for the dimension, you can select the relevant option ‘Generate help node’ in the dialog box for a new dimension. In the graphic window, you can then click the location on which the help node is to be generated.
The generated help nodes are listed in Table 1.1 Nodes provided with the corresponding comment and can be selected by using the ‘Select Special...’ function, if required.
For example, this option is useful when you need to create chain dimensioning for free surface reinforcement defined in RF‑CONCRETE Surfaces (see Figure). It is not possible to use the corner points of the individual reinforcement areas for the definition of a new dimension without creating a help node.
