SOLIDWORKS assembly equations come in handy when working with assemblies that require some linear or circular pattern, such as an assemblage of a flange and a set of bolts. Assembly equations in this type of scenario would help change the number of holes on the flange, while at the same time reducing a number of bolts at the click of a button. In this particular demo, I will be taking you through how you can set up these assembly equations.
First, create the flange part.
Save this part then move it into an assembly. In your assembly, go to the tools drop down menu and click on ‘Equations’.
Choose a name for the variable and set the desired number. Link this to the number of holes available on your flange component. This should also be done on the part level.
Next, move to the design library and add a bolt that fits in the hole from the toolbox. Remember that in order to use the SOLIDWORKS toolbox you need to have the add-in enabled.
Mate the bolt in the hole and create a circular pattern for the bolts to fit in the number of holes.
Create another equation linking this to the number of holes on the flange. With this setup, are able to change the number of holes with the corresponding number of bolts on the flange at the click of a button by simply varying the set parameter, which in our case is six. One is able to input the number of holes desired, thus creating different flange configurations. SOLIDWORKS assembly equation is, therefore, a rather neat tool that can save you time on your next project.
