Cannot get solid body from selection - returns NULL

[DWhiteley]

I've used this code so far:

Ptr<Selection> bodysel = ui->selectEntity("Select component", "SolidBodies"); // this works
Ptr<Base> compb = bodysel->entity(); // this works
Ptr<Component> comp = compb; //returns NUL

I'm trying to assign what I select to comp.

HELP

The entity property of the Selection object will return a BRepBody object and then you're trying to assign it to variable typed as a Component.  That won't work.  It should be more like this.

Ptr<Selection> bodysel = ui->selectEntity("Select component", "SolidBodies"); 
Ptr<BRepBody> body = bodysel->entity();
Ptr<Component> comp = body->parentComponent();

Thank you Brian, worked a treat!
