dwgdirect fails to load correct layers
dwgdirect fails to load correct layers
i have a dxf file that loads incorrectly with applications using dwgdirect.. (ours and odamfcapp). only the '0' layer is loaded and all data resides on this layer.. whereas in voloview, intellicad, and our older appilcation utilizing opendwg, there are 3 distinct layers '100', '108', and '254'.
since i can't upload dxf files, what email address should i forward the file to?
thanks,
graham.
sorry about that, graham. it was a configuration problem. you should be able to upload up to a 5 mb dxf file now.
thanks evan.. much appreciated...
here it is.

the file contains no layer table.
since 1.12.04 dd creates new layers in such situation.
so layer information is not lost.

if it contains no layer table.. how come i get three layers in applications utilizing opendwg toolkit and voloview? all three layers in those applications are constant and never change. in dwgdirect only the '0' layer is visible and all the data is dumped on to that layer. there is something that you were doing prior to get these layers right and that autocad is doing right.
open the file with text editor and see - where is no layer table. and no any other table too - only entities section.
if an entity references a non-existent layer (it's possible because layer is referenced by name) a new layer is created with default properties at file loading time.
the effect you are writing about is a result of regression in initial 1.12 release. this regression effects loading of incorrect files like your example.
in 1.11 it worked ok and it was fixed at least in 1.12.04.

thanks sergey for you patience with me.. our customers from time to time will load archiac dxf files like the one i attached to this thread.. they usually expect the loaded data to be constant from release to release. now we can supply them with a solid answer on why they have missing layers..
i would recommend to upgrade to the newest 1.12 update.
1.12.xx versions have absolutely the same interface and upgrading would not take much efforts. the difference is only bug fixes.

we have the version just prior to the latest 1.12.04 release.. i'm going to hold out on upgrading until 1.13 comes out.
