Sometimes, we want to protect out designing details when we are presenting our designs. Those confidential information is the key for the whole design and functionality of the products. Hence, SOLIDWORKS has taken its action to protect designer’s sensitive intellectual properties of a product. SOLIDWORKS introduced “Defeature tool” to help designers to hide certain properties or details when they are required to show their designs to others.
With the Defeature tool, you can remove details from a part of assembly and save results in a new file in which the details are replaced by “solid”. Hence, you can then share the new file without revealing all the design details of the model. This feature also helps to save the less-detailed model to separate file and maintain references to the original part or assembly as well as specifying the details to be removed when customers configure and download the model.
The defeature is not only for Part designs also helpful for handling large assembly files. Since, Large assembly files has more number of components [internally & externally], the rebuild time and large file size is more. Therefore, defeaturing also helps users to share the files effectively. In this sharing, I with share with you guys about how-to setup the defeaturing process in SOLIDWORKS. All the contents are taken from SOLIDWORKS Tech Blog and all the credits go to EGS India. Well, let’s get started.
The above diagrams show the step 1 to step 3 in selecting the parts and components you wish hide from people. Removing components can be done by 2 methods. One is based on size and other is selective components. In the diagram shared, “selective components” option method is chosen. Hence, selective components and small components with 5% of assembly such as nuts, bolts, washer etc are removed.
After selection of components, I moved to next step to control motions of my assembly. Hence, a group so that motion is allowed between the groups.
Next, we are going to step 2 which is the motion selection. In this scenario, no retain to any feature and geometry. Therefore, the box is left empty. We shall proceed to next step which is removing the features we like. Since, all the necessary parts already removed in step 1. Hence, the box is left to be blanked again.
Hence, the final output will be as shown below. The amazing results with no extra feature is shown. Of course, the size of the assembly has been reduced and so do the size of the files. The rebuild time of the design in between “without defeature” and “with defeature” are different.
Before defeature, the size will be bigger as all the parts are squeezed inside a file. However, after defeaturing, the size of the file has been reduced hence shorter time is required to read and rebuild the contents.
