Fix the points

[alundr]

point(1,0,0) + (unitZ * 3) = point(1,0,3)

0 * 3 does not equal 3.  This is really confusing and really irritiating when you're trying to learn this software.  

Point(1,0,0) + (unitZ + 3) = Point(1,0,3) makes more sense.  My opinion anyway.

Thanks,

Andrew: While I am sorry you are confused and irritated, the first line is correct.  Your statement "0 * 3 does not equal 3" is true, but (UnitZ * 3) is a vector expression.  Assuming UnitZ is v<0,0,1> (as it would be at the root), then UnitZ * 3 is v<0,0,3>, which is a vector, which can be added to a point.

Your preferred formula will not work, because (UnitZ + 3) is illegal, since you cannot add a vector to a scalar.  It should throw an error saying that.

The Intent Language used by Inventor ETO incorporates geometric algebra, so you can use common operators like addition and multiplication on geometric objects.  This may be confusing at first, but it is very powerful and consistent.
