How to determine the kind of object selected by the user?

joshtargo

I need to get a direction vector. if the user selects an edge I can do it, if they choose a face i think i can use the normal to do it, but how do i determine the type of object the user selected so i can apply different code?

this is to align a new mate connector's Z axis.

If you use something like this in your precondition (see docs https://cad.onshape.com/FsDoc/library.html#QueryFilterCompound)

annotation { "Name" : "Direction", "Filter" : QueryFilterCompound.ALLOWS_DIRECTION || BodyType.MATE_CONNECTOR, "MaxNumberOfPicks" : 1 }
definition.myDirection is Query;

then later you can use the https://cad.onshape.com/FsDoc/library.html#extractDirection-Context-Query
 
e.g.

var extDir = extractDirection(context, definition.myDirection);

...then it works very cleanly.

my featurescript is to make a mate connector, and I want the user to be able to select an edge or a face to specify the direction they want the z axis to be.  
will extractdirection work for either of those picks?

I think it works!
