Topic: How to add an Hatch with Holes

[CADwiesel]

Using the addHatch Methode to create an new hatch and apply it to an given Polyline is not as difficult.
But if i want to create an Hatch or Solid with Holes inside, how i have to do this?
I Have the Polylines for each Hatch so how to reduce the small Areas which are all in an boundering Area from this?

[roy_043]

Is this about detecting nested polylines or about creating a hatch with islands?

[CADwiesel]

I think creating Hatches with Islands is the right meaning
Like Rooms with substracting Areas

[roy_043]

After creating the hatch object you must first use the AppendOuterLoop method. Next you can use the AppendInnerLoop method to create islands.
