Adding force in frame analysis

[Anthony]

I have a question regarding adding a force constraint in the Inventor frame analysis environment. When I add the fixed constraint to the beam the orientation indicator is incorrect - the square indicator being not parallel to the base of the beam. I would like to know why this is and as I am relatively new to frame analysis if I am doing something wrong. I have attached a screen shot of the placement of the constraint on the beam. Thank you

Define the direction of Gravity before anything else.

That did the trick, many thanks
