Sketch Complexity In many cases, you can produce the same result by creating an extruded feature with a complex profile, or an extruded feature with a simpler profile and some additional features. For example, if the edges of an extrusion need to be rounded, you can draw a complex sketch that contains sketch fillets (A), or draw a simple sketch and add the fillets as separate features later (B). A Complex sketch Extrude B Simple sketch Extrude Add fillet features Consider your design intent:Complex sketches rebuild faster. Sketch fillets can be recalculated much faster than fillet features, but complex sketches can be harder to create and edit. Simple sketches are more flexible and easier to manage. Individual features can be reordered and suppressed, if necessary. Parent topicSketching
