dd show ok autocad crash
i've got guerini.dwg that was prepared using dd 14.02.
using odamfcapp, freedwgviewer - previewing is ok.
but when i open the file in autocad i get strange splines.
why aren't they visible in odamfcapp. what is wrong with it?
unfortunately i couldn't attach guerini.dwg because when i try i got
404 http error. what is wrong? the file has 850 kb
can i mail it somewhere to check?

please send the file to .

another example
i've another example with similar problem look at the file autocadcrash.dwg.
is the reason the same as before ("this splines in question contain a number of coincident control points") ?
what can i do to avoid these situations. i generate lots of different dwg files from my app as a function of export.

spline looks different in autocad
i've got one more example. in attached files the splines in circles in freedwgviewer look like ellipse but in autocad it looks like rhombus.
don' forget to watch that file with white background.

about displaying last file in autocad.
this is question to autocad developers. arcs and splines are displayed as polylines. the polylines are cached.
if a viewport is initially displayed with such scale that a circle or spline are "very small" polylines have only a few points. and the curves are displayed not smooth in case of zooming.
it you invoke view/regen or regen all polyline cache is regenerated and the curves get smooth.

thanks a lot for your explanation.
