It seems, that there will be a problem with the ending of the file. There is something about this error: https://knowledge.autodesk.com/support/autocad/troubleshooting/caas/sfdcarticles/sfdcarticles/syntax-error-or-premature-end-of-file-on-line-xx-when-opening-a-dxf-in-autocad.html
Which version of RealityCapture are you using?
The end of your file should look like this:
SEQEND
