How do you create a surface from connected edges--fill() not working?

thomas_lampertius037

I am trying to create a surface from an array of edges bounded together forming a region. I am not sure if I am using the fill() function correctly, each time I try to use it I get this error: Precondition failed (surfaceOperationTypePredicate(definition)).

Hi @thomas_lampertius037,

Depending on the type of edge conditions you want, you will need to place the query in the appropriate location: either G0, G1, or G2.
Here is one way you can do this:

opFillSurface(context, id + "opFillSurface1", {
     "edgesG0" : qNothing(),
     "edgesG1" : NestedPockets2Fix,
     "edgesG2" : qNothing(),
     "guideVertices" : qNothing()
});

The 3rd input variable for the fill() function is a map, not just a single query of edges. The easiest way to do this is to assign NestedPockets2Fix to the "edges" property of the mapping. This should replicate what the fill feature does, automatically sorting continuity type behind the scenes. You may need to add boolean values for addGuides and showIsocurves.

fill(context, id + "Fill1", 
     "edges" : NestedPockets2Fix,
})

@mahir that's legit. I didn't know that. This will save me some if statements.

@MichaelPascoe Keep in mind the fill() feature has some other overhead that may or may not slow your code down in exchange for the simplified implementation.
