Normal vector extraction from plan

[[Yo...]]

Hi everybody,

 

I have a workpiece to measure but don't have any CAD model of the part, and then no nominal vectors.

I would like to know if it was possible to extract the normal vector of a plane (after probing) and to put the values into the i, j and k vectors of a point feature.

That way, I'm sure I'll be measuring with the vector that's normal to the surface.

After a plane probing and generation, I just have the angle of it in the alignment (A1 and A2).

 

Thanks

Correct me if I'm off target, but I think a plane will report in ZX XY, or ZY, XY, etc (A1 and A2) and not vectors like a Point.

How ever, you should be able to convert the plane A1 and A2 values to vectors online or maybe this excel file will be of help.

I don't recall who the author is.

Hi Richard,

When you define a plane you have x, y, z and a1, a2.

i attached a picture for example .

 

the file you shared is is awesome ! 
I will try to convert it manually but maybe someone how to proceed automatically in calypso.

Hi Yohan,

 

you could define a secondary alignment with your plan on spatial rotation, and use this alignment  for you point, so your point will be a i j k 001  in relation to your alignement/ plan

Just add a formula for you points i, j & k.

getActual("Plane1").normVector.x /.y /.z

 

Or switch to show vectors if you only wish to see it once?

Hi Eric,

Thank you for your solution.

 

how I can show the vectors X, Y and Z instead of A1 and A2?

 

thanks

Hi Mihael,

 

Thank you!

Works well 🙂
