During the cooperation between the structural and design engineers, the DXF format is often used if there is no direct interface. However, the geometrical data of these DXF files are not always accurate. For example, an inaccuracy in the third decimal place is not noticeable, but it can lead to numerical problems when generating the FE mesh in RFEM.
In RFEM and RSTAB, there are two predefined unit profiles available by default. These profiles cover the metric and the imperial systems of measurement. You can individually adjust the units predefined by Dlubal Software, including the decimal places used. To avoid losing the changes you have made, you can save a new profile for the units (see Item [1] in the picture). The stored profile can be loaded again (see Item [2] in the picture) or transferred from PC to PC. To do this, simply copy the content of the "Units" folder in the RFEM or RSTAB file directory from one PC to another (see Item [3] in the picture). In this way, you can achieve an office standard regarding the units used in all your workplaces.
When changing the units from the metric to the imperial measurement system, it is not necessary to change all the units individually. To do this, corresponding unit profiles are available in the "Units and Decimal Places" dialog box, which you can activate as shown in the picture.
The determined values for the influence ordinates are displayed as decimal numbers with up to six decimal places by default. This is usually sufficient for the influence lines of internal forces.
