Problem with drawing style

[ahmed_007_008]

So I used my drawing style to get a plan view for my shed purlins and horizontal bracing. the problem that we I generate the plan view for this, the horizontal bracing does not show on the drawing. Can anyone help me with this am working on project now and  need this to be fixed. I attached file for the model and pics for the problem from AS. I tried to solve this using the properties of Viewport and tried to Camera something the vertical bracings do not show on plan. thank you

Seems to be a problem of an object which will not be shown because of a specific modelrole.
Please show us your detail style which you use and we could give you a bit more informations

Thank you very much for your response actually your response give me a hint of the problem and it was that I used the wrong drawing style " Plan " instead I should have been using the " Plan/Elevation detail view.
