This practical, familiar model shows various techniques on geometry creation. Multi-body part design creates two solids representing the cylinder and piston of this epoxy syringe. This model is mainly created with extrusion but some hybrid modeling is shown. Surface geometry is used to cut internal geometry of a solid model body where a shell feature would not work.There are examples of surface modeling including: cut with surface, filled surface, extend surface, offset surfaces, surface trim and surface knit. There is an example of creating a Rib using the "Parallel to Sketch" option. Solid features include: extrudes, revolves, combines, mirror, delete face, split lines curves and the split command. There are examples of circular and linear patterns and mirrored geometry. Download this part to learn more about Hybrid Modeling and how mirror and pattern Rib geometry.

This model shows a few of the mold tool features available in SOLIDWORKS. In this case the waffle iron is made from reversing the waffle geometry. The multi-body part has some simple sheet metal features along with standard features. There are also a few examples of hybrid modeling using solid and surface features to create some of the geometry. The features used in the waffle iron part include: revolves, sweeps, lofts, boundary surfaces, trim surface, filled surface, offset surface, knit surface, planar surface, edge flange, combine, mirror, projected curve and one delete face. Also included in the model is an example of a circular pattern of a linear pattern. A projected curve is used to create 3D geometry from two 2D sketches. The part does includes two of the automated mold features including: parting line, and tooling split.

This assembly has just three unique parts but it does provide a practical example of a chain component pattern. This chain component pattern functionality was introduced in SOLIDWORKS last year. There are three assembly configurations showing different catenary curves dependent on pulley location. The catenary curve is created using a lofted surface from one of the parts to create the "U" shape. Pulleys can be moved to see the chain update accordingly. There is an example of an intersection curve and a fit spline. Other features included in the parts include: sweep, revolve, planar surface, offset surface, and a surface loft. There are also examples of equation driven curves to create the surface loft sections.

This assembly has just four unique parts but it does provide a practical example of a chain component pattern. This chain component pattern functionality was introduced in SOLIDWORKS last year. There are few surface features used to create the grip on the tray. Other features included in the parts include: revolve, offset surface, trim surface, extend surface, surface thicken, a thin extruded cut and a mid plane revolved cut. There are some examples of converted and offset sketch entities. Download this file to get a short introduction to surfacing and also how to create a chain component pattern in an assembly.

This multi-body part is a functional piece of history originally invented in the late 1800s in New England. It is a yankee screwdriver also called a "push screwdriver" or a spiral screwdriver. It does include many of the internal parts that make up this tool. It is two examples of indent feature. There are several examples of the "delete face" command using the "delete and fill" option. The part has other features including: helical curves, helical cuts, , revolves, move/copy body, mirror, and circular patterns. There is one example of the new circular sweep function in SOLIDWORKS 2016 used to create a helical spring.

This multi-body part shows the inner workings of a coreless DC motor. Most of the geometry is made with extrudes and revolves but there are some examples of sweeps and one loft. There are two examples of the new circular sweep function in SOLIDWORKS 2016. This part also goes over some easy to understand examples of surface feature creation used to make some the geometry including the windings. Other features the model include are: combine, freeform, surface knit, offset surface, extrude surface, planar surface, indent, circular patterns and one swept cut. There are two examples of the wrap feature using the "scribe" option. Download this file to learn more about motors and how to use surface features to create more complex geometry.

Here is a part that everyone is familiar with. It is a Multi-body Part that has a some sheet metal features and two surface sweeps in it. It is mainly created with extruded features but does have some revolves sprinkled in. Other features in the light switch part include: a lofted cut, combines, solid and surface sweeps, edge flanges, axis, move/copy body, and two circular patterns. There is a unique example of a helical sweep for the internal spring that does not use a standard helical curve to create it. An "intersection curve" is used to create a 3D sketch for the sweep path similar to how a projected curve works.

This assembly has two parts. One part is used to help create an animation. The nail clippers model is a multi-body part with a very unique combination of sheet metal features with some basic surfacing features sprinkled in. There is an "in context" sketch feature that helps animate the flexing of the arms. The features included in the nail clipper part include: revolve, lofted surface, offset surface, trim surface, extend surface, knit surface, edge flange and a split line curve.

This model introduces some of the terminology and concepts of a camshaft. Cam Lift and Cam Lobe separation are discussed and shown in this model without being overwhelming with information overload. There are multiple examples of copying and moving solid bodies with a Combine features merging all the bodies back into a single body. There is an example of helical gears created with a swept cut. Also included in the model are circular patterns and a linear pattern. Download this file to learn more about camshafts.

This small but feature packed assembly consists of a few multi-body parts. The wheel and wheel boss are multi-body parts and have several examples of circular patterns. The chariot part is another multibody part made of extrusions and revolves features and has examples of the rarely used curve driven pattern and move face command. Other features in the parts include revolves, thins, full round fillets, split line curves, delete face and the combine command. There are two examples of the new bidirectional sweep function in SOLIDWORKS 2016. There is even a little bit of chariot trivia sprinkled into some of the comments.
