If we have a part like on the picture and we want to cut a complex feature on it, we can use a loft cut feature for this.
We can see that we have 3 profiles. We activate the loft cut feature and the property manager appears on our left side. The property manager is the same as on the loft feature.
We select all three profiles and we get a preview of what is going to happen.
This is the part we get.
if we add a guide curves we can get a full control of the loft cut. This feature can be used for complex shapes.
