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.

@owen_sparks you can use the sketch plane that the point is on with evOwnerSketchPlane

Two 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.

Hi Cody, thanks for the info.  That sounds perfect.

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.

Parameter	Type	Additional Info
arg	map
entity	Query	The sketch entity. May be a vertex, edge, face, or body.

Thanks Gents.

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

Cheers,
