We all know there are multiple ways to construct models inSolidWorks. No single method is better or worse than another, but

some methods will allow for:

1. Easier modifications to models. 2. More robust or stable models.

3. Models that are smart. 4. Models that are more useful for everyone.

Developing Best Practices is our way to identify whichmethods work best for the types of designs we create

everyday.

Hardware Models

Below are 4 examples of a 5/16 shoulder bolt model. We will explore how each was made,and identify the Pros and Cons for each modeling method.

When creating models of hardware (outside of Toolbox) it is important to accuratelyconstruct a model that represents the real life part. Accurate models help us to identifyinterferences and clearances in our top level assemblies. However, many times users willcreate too much detail in a model that does not add to the functional accuracy of themodel.

In this method the model was constructed ofseveral circular extrusions to construct the main

body of the bolt. After this, the hex-socket was added, along with chamfers to give a lead-in onthe threads and add detail to the bolt head. Cosmetic Threads are used to indicate the threads.

Model Pros:Easy to modify the length or diameter ofthe model.Quick rebuild time.

Model Cons:No accurate threads available for sectionviews if required.7 features in the Feature Manager.

Method 1- The stacked build.

Method 2- The revolved body.

In this method, the entire profile of the bolt was created in the base sketch, and the sketchwas Revolved around a center axis. After this the hex-socket was added along with

Cosmetic Threads.

Model Pros:Very fast Rebuild time.Minimum amount of features in the FeatureManager.

Model Cons:Very time consuming to modify the modelif required.No accurate threads available for sectionviews if required.

Method 3- The faked threads.

In this model, several circular extrudes were used to create the body of the bolt. A solidextruded feature representing the threads had a Cut-Revolve feature that was Linear-Patterned to simulate the threads. Details of the bolt head include the hex-socket and chamfer

detail.

Model Pros:Realistic looking threads, but not 100%accurate.Visually appealing model.Decent Rebuild time.

Model Cons:Performance degrading Rebuild time.Inaccurate threads for section view use.

Method 4- The real deal.

In this model, the bolt was created with several circular extruded features, with the addition ofaccurately modeled helix-based threads. Details in the bolt head include the hex-socket and

chamfer.

Model Pros:Realistic Threads, suitable for section viewuse.Highly accurate model.

Model Cons:Performance degrading Rebuild time (9.5 timeslonger than other models).7 features in the Feature Manager.

Comparisons

Looking again at the different models, there doesnt seem to be a great difference in thelook of each bolt. All versions of the model would serve its purpose in the top levelassembly, however some are more resource intensive than others. The more resources (i.e.longer Rebuild times) a model needs to resolve, the longer it takes for your computer torebuild modifications in the top level assemblies.

A suitable compromise would be to use Methods 1 or 2 when creating hardware models.Method 1 allows for fairly easy modifications to the model, while Method 2 provides theshortest Rebuild time.

In certain situations or special cases, it might be desirable to show simplified threads as inMethod 3, or full blown helix-based threads as in Method 4. Just keep in mind that thesemethods use more memory and more processing power of your computer, and the morehardware models you have based on these methods will increase your down time with

SolidWorks.
