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.


improve your rendering


For generating a realistic image in SolidWorks photo rendering, we often use default photo rendering settings. Still there are some more tips to be followed for our improvement. Here are 6 rendering technics to be followed in SolidWorks Photoview 360 to generate highly realistic images.

1. Adjusting the Image quality:

Before starting rendering do some initial setup by going to tools>options>document properties>image quality, by sliding draft quality to high we get smoother curves in both modelling & rendering.

Do You Know Which Design Cost Less?

We normally think of optimization in terms of reducing mass or increasing performance of a product, but often the underlying goal is to reduce product cost while achieving a target performance.   Product cost may be a function of many factors such as material type, amount of material used, manufacturing process, number of parts, assembly details, and more. The relationship between cost and design variables (e.g., shape, material, gauge thickness, location of features, etc.) is highly implicit. In other words, it is often difficult to understand the direct effect that changing one or more variables will have on cost. But mathematical design optimization has the ability to efficiently explore these complex relationships. For this reason, a powerful tool for achieving a cost effective product design is essential.   It is tempting to reduce design complexity by focusing on just one type of design variable. For example, cost reduction efforts may consider only reducing gauge thickness, or changing material type, or changing shape

to reduce material usage. By themselves, any of these approaches may yield some benefit in terms of cost reduction. But the biggest cost savings are usually achieved by taking advantage of the strong coupling among shape, material properties, gauge thickness, and other variables.   Further, the least expensive material may not always lead to the lowest cost design, since performance and mass are often strongly affected by a change in material. Simultaneously optimizing the distribution and type of material within each component is the best way to achieve both high performance and low cost Benefits

Dedicated Multiaxis Programming for Multi-bladed Parts

Conventionally, one of the most complex 5-axis challenges is creating toolpaths for impellers, fans, and marine screws. These parts are widely used in power generation, energy transfer, and propulsion.


Blade Expert is a powerful, user friendly custom application developed to generate efficient, smooth, and collision-free toolpaths for these complex parts. It minimizes unnecessary air passes at the machine, delivering a highly efficient toolpath with superior finish quality and accuracy.


Multi-bladed turbine parts and impellers come in different configurations, but Blade Expert’s common sense operation process turns these machining challenges into routine solutions. And, the interface is the same one used by all other multiaxis toolpaths, ensuring a short learning curve.

Particular features include:
•     Precise, efficient, and smooth cut pattern.
•     Supports straight, bull, and ball nose cutters.
•     Automatic stock model awareness eliminates air-cuts.
•     Automatic tool axis control for safe toolpaths.
•     Accurate tool tip control means seamless blending and transformation.

SIM technologies Pvt Ltd being the Authorized Reseller for Mastercam in India, provides the industries who are into manufacturing complex 5-Axis parts with Blade experts.
