Salome geometry

I have tried to follow Tutorial 1 for geometry modeling and meshing in Salome. When I get to the circle and push the \"arrow\" button, I am not presented with any choices to select vertex_1. Help would be appreciated.

Hello,

after you click on the Arrow button near \"Center Point\", try to select \"vertex_1\" by clicking in the tree view on the left. Does it work now?

If you have still some troubles, try to work in an OCC view as it is working much better in the GEOM module:
to create an OCC view, select menu Windows->new OCC window (or similar). I have seen that this view is much more reliable when you need to select geometrical entities in 3D views.

Thanks. Clicking on the tree at the left works.
