In this video, we will showcase the feature BOUNDARY SURFACE with the Trim by Directions 1 and 2. The first time a co-worker showed me this trick I was like wait, WHAT? Oh man, how could I have never seen these two options in my feature manager before now? What we will do is create a Boundary Surface and then use the curves that we used to create the surface to also trim the surface. This dramatically reduces design time because now I do not have to create an additional surface to trim the new surface to the final shape. We can edit the curves and adjust the final shape. We also show the flip connectors option that sometimes happens with a Boundary surface another modeling tip that is a time saver.
