My company has recently switched from Solid Works to Creo 2. In SW you can crete a 3D sketch by simply drawing lines and arcs and then constraining them to lock location. We then use a Sweep feature to create cores through a casting. The only way I know to do this in Creo is to create a series of points and connect the dots. This seems like a LOT of trial and error on location. Is there another way to create 3D sketches on the fly?
