Trident: This model of a famous spear shows how to make advanced geometry without using surface features. This part was created with only standard solid body features. Even though the final model is a single body, there are some multi-body techniques to allow for isolated cuts and a shell feature not affecting the whole part.
The features used in the trident part include: revolves, lofts, move face, combine, mirror, scale and one delete face. There are multiple loft features including two “centerline” lofts that act like “swept lofts”. The scale feature is used twice to save time reducing the size of geometry in a pattern versus creating smaller versions from scratch. There is one example of a face fillet using the hold line option.
