software hidden line remover problem
hi,
i'm using the exgsgdivectorizedevice for printing in hidden line render mode and i'm having some problems. (the dwgdirect version is 1.14.02). look at the attached pictures - pic1 is my drawing as render in our opengl device and pic2 is the printed image. did someone have a similar problem? what may not be set properly for the odgihlremover object?
thanks in advance for any help.

the problem may be that my hlr object receives a wrong matrix: here are again two pictures that show the problem. but i really cannot see where the matrix goes wrong. may be the fact that my printing code does not print in normal hdc with positive y to the bottom, but prints in dc set to tenths of millimeters and the positive y is to the top?

software hlr had some tolerance problems in 1.14.02 (they were fixed).
i think these artefacts are due to these problems.
sincerely yours,

ok, thanks, we'll check in the next version.
