Computing transform for use with Instantiator

burt_harrisburt_harris Member Posts: 7 ✭✭
I'm writing a feature with two primary inputs:  a face on which to add the whole-lie feature, and a set of points specifying locations to instantiate them.   I'm having some trouble figuring out how to combine the two into a transform for the effect I'm looking for when calling addInstance().   

My current effort uses transform(worldToPlane3D(plane, vertex)) to map each of the input points onto the feature's plane, but I also want the plane to control the orientation of the feature, which isn't happening.   I've also used a transform derived from the plane so that the features are always facing the right way, but with that they always appear at the origin.    How can I combine the orientation from one transform with the location from another?
