Can anybody tell me why the Drain pit line work turns up in Trueview viewer, but when imported to TBC there is no line work to be seen?
I have tried converting it back to dwg 2007 with no luck.
The 1st picy is Trueview with green arrows showing Line work, 2nd picy is TBC same area showing no line work.
