Hello Christophe,
The default surface representation mode is a cross of dashed lines.

With OpenCASCADE you can have other representations: cf. 
Tools->Options->Geometry->Aspect->Surface display.

To save your preferred options: File->Save options as default.

Thank you for taking the time to help. Just what I was missing.

I am very new to gmsh, and I have a few questions about the learning aids 
that are available:

1. Where is the user interface defined besides the reference manual 3.4 & 
3.5 (for example all the windows/tabs accessible from 

2  The video tutorials at http://gmsh.info/screencasts will be very helpful 
in learning the UI - it was in attempting to repeat the first one that I got 
stumped when my results differed from that of the video.  Are there other 
screencast tutorials besides the ones collected at 
http://gmsh.info/screencasts ?

3. Are the demos at http://gitlab.onelab.info/gmsh/gmsh/tree/master/demos 
any help in learning the UI?   Do the demos proceed step-by-step or do they 
simply execute at once the construction commands that they contain?

4. Finally, Are there other forums where I may interact with experienced 
gmsh users besides this list?

Kind regards,
