Schematics generating empty diagram ArcGIS 9.3

[RohitShome]

Hi,

Am trying to generate the schematic diagram based on trace. I've created a schematics data set using the steps mentioned. However when I generate the schematics diagram, it generates only an empty diagram. Have I missed something??

Thanks,

Hi Rohit Shome‌,

Could you please let me know if you could solve this issue. I am also running into a similar issue. I am able to generate a schematic diagram through addin in ArcMap. but with the same code, if I run it as a console application outside ArcMap, it is generating the empty diagram. 

Any inputs would be very helpful.

Thanks a lot in advance!

With Regards,
