How do I use the centroid as a vector?

MichaelPascoe · September 2020

I found the centroid of my sketch with this:

var centroid = evApproximateCentroid(context, { //Finds the centroid of the selected face.
                    "entities" : definition.selectedFace
        });

The hint says it returns a vector, but when I try to use the variable "centroid" as a position in my sketch point, it says it's not a vector. and throws this error: Precondition of skPoint failed (value.position is undefined || is2dPoint(value.position))

Code for my sketch point:

var pt = skPoint(sketch, "point1", { "position" : centroid});&nbsp; &nbsp;

Once the point is placed, how would I query the point so that I could use it in a loft?

centroid is 3d vector while for sketch point you need 2d, so you need to transform it like that: centroid2d = worldToPlane(skPlane)*centroid

is realPlane2 a query or a Plane?
You will need to do evPlane to get the plane object for the plane query.

I tried this:

var centroid2d = worldToPlane(realPlane2, centroid);

realPlane2 is the plane my sketch is on.

I'm still failing to implement it correctly. It throws this: Call worldToPlane(Query (map), Vector (array)) does not match worldToPlane(Plane, ...)
