The import a DXF file initially seems to be working, but there is no data there.
What is the cause of this?


There can be several reasons for this.
  • It may i.a. be caused by the fact that the DXF file contains only blocks that have first to be separated e.g. by means of the ‘Explode’ function .
  • Another source of problems may consist in the fact that a specific layer is selected for import in the ‘DXF ASCII Formats’ tab of the RFEM or RSTAB import dialog box that either does not exist or contains no data.
  • The type of backup in the CAD program may also cause some problems. It is possible to save DXF files in the binary DXF format. Their advantage consists in saving about 25% of the memory size. However, they cannot be processed by RFEM and RSTAB. Therefore, to save the DXF file, the ASCII format should be selected in the CAD program.
