The myopia that is endemic with this outlook pre-supposes that Architecture in no way encompasses graphic design.
Were you to actually study Architecture [the course, not the buildings] you'd find a whole swag of included subjects. from Sociology to Life Drawing....AND, shock-horror.... Graphic Design, Sciagraphy, Technical Drawing, Rendering, Modelling, ad nauseum.
Text [if that is what pre-occupies you] is another design element, but it is only one.
It can be incorporated in the oldest visual imagery...eg Tattooing, or in anything done since....BUT it is one 'design element' within a myriad of others.
I repeat....ALL art is Graphic Design.
However..
All Graphic Design is not necessarily 'artistic'.
There is a difference.
Anyone wishing to get anywhere in the field of publishing design, advertising, logo creation.....graphic design...call it what you will...will be at a total disadvantage if they do not look beyond the end of their noses.
