i still don't very understand the problem. could you post a fragment of issuing source code (completely describing what you are doing)?
if you are using our vectorization, and getting invalid coordinates - then you most probably are doing something wrong. please study our odvectorizeex and odamfcapp samples, they successfully solves this task.
if you are trying to implement your own dwg vectorization framework, then it is very complex task, you need:
1) take into account all model transforms. line with coords of ends (x1, y1, z1) and (x2, y2, z2) can lie in block that are inserted to other block with some transform, and this other block can be inserted to current space with some other transform, etc
2) transform from world to eye coordinates - take into account camera properties of current vectorizing viewport.
3) apply linetype.
4) apply spatial clips (if any). some parts of dwg file can be not displayed due to spatial clips existence.
etc...
sincerely yours,
