(OP)
I have a quick question:
I have a drawing with 3 views (Side/top/right) and an Isometric view.
What standard would I go to, to give guidance where to layout these views on a drawing?
I.E. ANSI Standard XX.XX.XX

RE: General Drawing Layout Standard Help:
There is no pre-determined view layout in creating a good drawing. Start with the view with the greatest number of features visible. Project additional views from there, but only as many as needed to fully define the part.
Some simple parts may only require one view, or none for that matter (such as a sphere) if it can be easily described with words.
If you know that three views will be needed to define your part, the standard will explain what is required as far as layout.
This isn't homework, is it?

RE: General Drawing Layout Standard Help:
For instance back in my little part of aerospace in the UK, on the top level drawing the first view was always a side view with the nose to the left.
Most component drawings kept the same orientation, with only occasional exceptions, this helped checking fit etc on lay-outs.
While a bit less necessary with 3D CAD the idea of modelling & drawing everything in the same 'final assy orientation' has some benefit.

RE: General Drawing Layout Standard Help:
My colleague says that putting the isometric view on the left is just fine. To me thats just looks bad and isn't very professional.
Check out the drawing I uploaded to demonstrate what I'm talking about.
RE: General Drawing Layout Standard Help:
Put it anwhere so long as it's out of the way of the main views, notes, parts list, title block, rev block...
A company standard on this might have some merit but this wouldn't be something I'd die in a ditch over.
If this is the biggest problem you have right now I'd love to swap

RE: General Drawing Layout Standard Help:
I am running SolidWorks here.
When I am ready to make my drawing, I look at the 3D_model and I work out what views are needed for a clear description of the part. I might need two. I might need five or six, plus some sections.
In nine years of SolidWorks, I have yet to use an actual isometric view. Often, I do not bother applying a 3D_view, because it provides no useful information. Every other time, there is specific information I want to show off, and I rotate the view so that the viewer can see this. This is what goes on the drawing. If there is another specific piece of information I need to show and I cannot get it into the 3D_view, I rotate the 3D_model again, and apply another one. Often, I rotate and orient 3D_views to fit in the space available. Put yourself in the place of your reader, and try to anticipate what will confuse them.
I try very hard to draw everything at 1:1 scale. I try to get everything on the smallest sheet possible.
Drafting is a language, not a set of procedures. You should be trying to communicate. Follow the projections. Apply dimensions and tolerances as per the standard. Add section views and details as per the standard. Make sure all the information the user requires is shown clearly.

RE: General Drawing Layout Standard Help:
In SolidWorks, if I put my isometric view on the right, I am going to get a specific isometric view. Perhaps I do not find that particular view useful. Perhaps that position is where the projection off my secondary view goes.
I do not see a need to place all my views in the same place on my drawings. My drawings are clear because I provide adequate space around my view, and I follow the projections shown by my projection symbol. Your standard breaks down if I need a right hand view and a left hand view. It breaks down if I don't need the right hand view.
RE: General Drawing Layout Standard Help:
Solidworks allows you to move Isometric drawings aka 3d views, independently of view orientations. I could place a left side iso in the top right corner if I wanted to.
RE: General Drawing Layout Standard Help:
Your school or your prof may have had that 'rule', but I'd say that's about as far as it goes.

RE: General Drawing Layout Standard Help:
However, I don't think any standard exisist that says it must go in the upper-right. And with europeans using first-angle projection, it would be a reverse 'L', so the upper left would be the ISO view location.

RE: General Drawing Layout Standard Help:
One thing that I am pedantic about is company title blocks. We follow ISO standards so ANSI may be different, I'm not sure. ISO 7200 requires the bottom right corner of the drawing WILL contain the drawing identification number. Just above or just to the left will be the drawing title and the name of the legal owner. Every company I have worked for, American and European, has followed this standard but I see many drawing formats, including the one posted above, that do not. If you want something to get me going about professional looking drawings, start with the title block.
Rant off.

"since I was taught this for my 4 years of engineering."

That could be very true, it was just standard for my professor to mark my drawings up if I put the iso in a different location. I just assumed this was an industry standard as most the "real world" drawings I saw were of this same format'ish.
RE: General Drawing Layout Standard Help:
As MM posted, the most likely reason to place it on the right side is to allow for notes on the left side. If the company DRM specifies that notes shall be on the right, chances are that the iso (if one is specified) will be on the left.
I'm with drawoh on this subject; the object is to clearly define a part. Pre-specified required views are not necessary to accomplish this, and can add confusion to the drawing interpretation.
I also rarely use iso views, with the biggest exception being an exploded assembly. Even those will have detractors claiming that they aren't really necessary, but they do often simplify the assembly definition.

RE: General Drawing Layout Standard Help:
At a previous employer, we put an iso in the upper right with overall material dimensions so that the person ordering material could page through a stack and see what material to have cut from stock or ordered.
