ByCoordinateSystems (i.e. the Tekla API method)? AlignCoordinateSystem (the AutoCAD .net API method)? What are they? What do they mean?

What problem does it solve?

I have some treasure, buried somewhere.

I know how to get there from my town.

• Go 10km forward, and then 5 km left, and then 2 km right.
• Walk forward 10 steps, and now
• dig.

This is great from my current location. But how will you get there from YOUR location? Without changing the location of the treasure, I can tell you how to get there, from your location by aligning coordinate systems.

But it can be confusing. Here’s how I think about it intuitively. Forget the maths, just think about it intuitively.

Consider both examples:

If you think about it that way, it will be much harder to get confused.
