Featured design rule
DFMPro
v3.5 features a design rule for welding, which is critical from ensuring the strength of a fillet weld joint. Fillet welds are typically used on T-joints. Fillet welds can be as strong as or stronger than the base metal if the weld is the correct size and the proper welding techniques are used. Under welding can result in a weak joint causing failure during operation. Over welding results in not just waste of weld material but also time required to do the weld. It can also lead to residual stress in the joint. 

The rule is based on based practices for welded joints. The designer can quickly verify all the weld joints in the design using this automated rule and make corrections where required.



Upcoming rules
- Additive Manufacturing (3D Printing)
- Composites manufacturing

DFMPro is a design assistant solution for validating designs from manufacturing point of view right at the design stage. It automates manufacturability checks, which helps design and manufacturing engineers validate the design quickly. It assists identification of design areas that are difficult, expensive or impossible to manufacture, assemble and service. It works on the principle of ‘Right First Time’ by validating manufacturability guidelines right at the design stage. These guidelines can be easily configured as per organizational requirements in the form of rules. It also facilitates a collaborative design environment by generating reports, which are compact and easy to share.
