Hi, we are working with SUMO-GUI v.032 and the TraCI C++ code from v0.32.

The error might be caused by mixing client version 1.0.0+ with sumo version 0.32.0 (there was a protocol change in 1.0.0) regards, Jakob Am Do., 11.

I use sumo 0.32 and was wondering if it is possible to get the coordinates of a polygon via TraCI.
