Pointing a dish regarding the building wall direction

[polgyver]

This might be useful for newbies to this hobby. Turning the dish on its mast, sweeping the horizon by 15 - 20 degree or more, is time consuming. The dish pointing could be done faster if the direction could be pre-determined, by using a good compass. If there is no compass, then usage of www.dishpointer.com should be helpful, with 2 satellite azimuth comparison and little math.
As an example, there is description of pointing the dish to popular bird, 97 W, in Toronto, whose streets do not run parallel to geographical coordinates.
Three annotated pictures follow:

That's one thing I like about the city that I moved to. All the streets are north-south or east-west, and my balcony faces due south. Setting up my motor was far easier than I expected. Fine tuning it, on the other hand....

When it first read the title I thought "How does he know that the bird they seek will be over Mexico relative to their location?"

Yesterday I made a template and checked it with the dish in my backyard (angles seemed OK).
Today I used the template for installation of dish at customer's place (40 km West of my place).
