Parallelism measurement

[alexk]

So I'm having trouble with a few parallelism measurements in a program. It's outputting pretty nonsensical measured values and I can't work out what I've done or not done. Code below for one of the measurements and the features it uses, any suggestions?

Thanks

Just looking at the vectors, there's a problem...
The line is approximately along X, the datum D as a vector along -Y.
You construct a plane parallel to a line.... But there are an infinity of planes parallels to a line...
Maybe you should create the plane parallel to PL1 ?

[KIRBSTER269]

I See Plane D to Plane B unless they changed it, but that doesn't change Jefferys fact. those 2 planes are perpendicular not parallel.

[KIRBSTER269]

I just seen what he constructed that out of Jeffery, my apologizes.

Why you trying to make me spit out my morning coffee...

[JEFMAN]

Maybe because it's not morning ?

[Sora5]

Haha, it's always morning somewhere in the world!

[alexk]

Not my finest moment... Have actually constructed plane B to be somewhere close <0,1,0> and lo and behold... Thanks guys.

I am struggling to see how you can construct a stable parallel plane from a circle and line.

[KIRBSTER269]

easy as spinning a dreidel.

[alexk]

I definitely can't, it's all I have to work with though.
