I am trying to visualise some iges files using draw. I am having two problems. First I can't get the surfaces to display, only wireframes and Second DRAWEXE crashes when it tries to process mouse move events.
For the first I am running these commands in DRAWEXE:
NewDocument d XmlXCAF
ReadIges d file.igs
For the second, I get this backtrace:

As you can see V3d_View::Viewer is returning an invalid handle. I don't run windows so I can only say this is an issue under Linux.
Help with either of these two issues would be great, many thanks.
This crash is due to a regression introduced in 6.3.0 when DRAW's View3d was migrated to NIS_View. The API in ViewerTest has been re-tailored to it *too much* and did break a compatibility it could have kept given that NIS_View inherits V3d_View.
Here are the patches I have made to get it back to work. File VieweTest.cxx:
