Importing a DXF file initially seems to work, but there is no data.
What can be the reason for this?


There can be several reasons for this.
  • Among other things, it may be due to the fact that the DXF file contains only blocks that have to be separated first, for example with the "Explode" function.
  • Another source of problems may be that a specific layer is selected for import in the "ASCII Formats DXF" 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 problems. It is possible to save DXF files in binary DXF format. They have the advantage that the files save about 25% of the memory size. However, RFEM and RSTAB can not process them. Therefore, the ASCII format should be selected in the CAD program to save the DXF file.
