【转帖】spline Reading Different From Autocad
 
spline reading different from autocad
spline reading different from autocad
i am using dwgdirect 2.5.1, and both the brava free dwg viewer and the odamfcapp show me different values for the control points and knots than i see in autocad map 3d 2009. see the attached data and screen shots.
is there something invalid about the spline definition, or some additional work to be done to produce the same results?
thanks

the smaller spline does not pass through the fit points. seems to be related with fittolerance.
fit tolerance is not supported in dwgdirect yet.
the smaler spline has fit tolerance close to the splines extents (4.5) so appearence in dd and autocad differs significantly.
larger spline has fit tolerance 0.1 and looks better.

thank you for that comfirmation.
