Hi @donaldleigh. A drawing section view always includes a sketch to define the section line geometry. When creating a SectionDrawingView by iLogic, using the DrawingVeiws.AddSectionView method, you must supply a sketch as one of the input variables. And when retrieving an existing SectionDrawingView object, that object has a Sketches property that will contain any sketches used to define the section line geometry. Since that property is plural, it returns a DrawingSketches object, which is like a collection of drawing sketches, so you will have to get one of its items to get the actual DrawingSketch itself. Once you have that sketch object, you can edit its geometry, add or remove geometric constraints, add or remove dimensional constraints as needed using the appropriate iLogic codes for doing those things.
