Using FS can we create a sketch on a face of a part or only on Planes?

Hi Folks.
I'm playing with my first FS.
Using FS can we create a sketch on a face of a part or only on Planes?
More broadly I have an input of a single vertex (from a sketch on the surface of a solid part). I wish to create a sketch here then add some geometry to work with.
What's the easiest way to accomplish this please? (The Slot Tutorial has us creating new planes but from a coordinate system and a line. I just have a point to start with.)
Many thanks for your help,
Owen S.

cody_armstrong Moderator, Onshape Employees, Developers, csevp Posts: 215@owen_sparks you can use the sketch plane that the point is on with evOwnerSketchPlane5

ilya_baran Onshape Employees, Developers, HDM Posts: 1,202Two things I can see: you need to use newSketchOnPlane instead of newSketch (the former takes a plane, the latter takes a query for a planar face) and you need to pass context into evOwnerSketchPlane as evOwnerSketchPlane(context, definition.targetpoint).
Actually, the third thing is that you should filter the targetpoint to only allow sketch entity selections:
annotation { "Name" : "Select Sketch Point(s)", "Filter" : EntityType.VERTEX && SketchObject.YES }
Hope this helps.Ilya Baran \ VP, Architecture and FeatureScript \ Onshape Inc5 -

Sorry to be a PITA but would you mind helping with the syntax?
I have this in the precondition:-
// Target Point(s)
annotation { "Name" : "Select Sketch Point(s)", "Filter" : EntityType.VERTEX, "MaxNumberOfPicks" : 1 }
// or for unlimited picks
// annotation { "Name" : "Select Sketch Point(s)", "Filter" : EntityType.VERTEX }
definition.targetpoint is Query;
...and then later in the function:-
var sketch2 = newSketch(context, id, {
"sketchPlane" : evOwnerSketchPlane(definition.targetpoint)
});
which is incorrect, throwing the error "Function evOwnerSketchPlane with 1 argument(s) not found".
What is the correct method to evaluate this point and use it to create the sketch?
-----------------------------------------------------------------------------------------------------
The help file tells us we can use a vertex:-
evOwnerSketchPlane (context is Context, arg is map) returns Plane
Return the plane of the sketch that created the given entity.
arg
map
entity
Query
The sketch entity. May be a vertex, edge, face, or body.

Hope this helps.
Extra filter added to precondition and:-
var sketch1 = newSketchOnPlane(context, id, {
"sketchPlane" : evOwnerSketchPlane(context, {
"entity" : definition.targetpoint
})
});
Did exactly what was required.
Your help is appreciated
