loading smoothing polyline
loading smoothing polyline
the 2d polyline smoothing by spline in version 1.06 was represented by oddb2dpolyline object. so i could separate vertexes with type k2dsplinectlvertex and don抰 display they.
but in version 1.07 beta this polyline represents by oddbpolyline and i have problem with separating control vertex.

could you send me a sample file illustrating the problem? i failed to reproduce it.

i just sent the sample file to you.

your 2d polyline entity is incorrect. it has flag "spline fit vertices added" set (bit 4 of dxf group code 70).
but curve fit type (dxf group code 75) is zero.
autocad 2000 treats the situation as if cubic curve fit type was set.
i will replicate autocad's behavior in dd but different applications and even different autocad versions may interpret incorrect entities differently.

you are right. but this is very strange. because this file was created and modified in autocad 2002. but i can抰 represent this bug. new files autocad write correctly.
thank you for explanation. so if i understand correctly in version 1.06 dd interpret this incorrect polyline same as autocad 2000 and starting 10.7 (and higher) as lwpolyline.

no. dd versions up to 1.07 converted such polyline to lw if file being loaded is of version less than current. starting with 1.07 current dd version was changed from r15 to r18 so you noticed the problem. in other words the same problem was in 1.06 if r12-14 file is loaded. starting with next dd release it will treat such polylines like autocad does.
