Hello again,
After importing the x-cam template i still get the same error message.
However i think i found the issue. when i check out the txt file generated by x-cam, i found this entry.
"mil_wallbig_4m_f";245531.546875;65689.03125;180.088;0;0;1;-4.76837e-007
I deleted the line and imported the file into TB and walla, the error message did not appear.
