VARY SKETCH PATTERN
Pattern is a common tool that we use to create instances of features or bodies were we all use this to easily create copies of features. But lot more options are available among them; one interesting feature is Vary Sketch pattern that we fail to recognize.
Vary sketch pattern is a tool used to easily vary the dimension and number of instance. For creating vent holes in heat dissipating areas in consumer products like, projectors, mixer grinders, sheetmetal enclosures, hair driers etc.
The trick in using the vary sketch option is that instead of selecting the bottom edge of the part as the direction vector, you would select the locating dimension of the seed feature. This option tells SolidWorks to pattern using the locating dimension as a driver to change the sketch as it would by changing the dimension. If you haven’t seen this feature before it can be an eye opener! SIM Technologies Pvt Ltd is an authorized reseller of SolidWorks.
