Blank Size Engineering (BSE)

Beginning with the 3-D part geometry, Blank Size Engineering can quickly unfold the flanges and flatten the geometry to produce a blank outline for blank size estimation along with piece price and scrap calculation. Product feasibility and cost analysis can be thoroughly evaluated using Blank Size Engineering.

Blank Size Engineering provides users with a fast and accurate method for developing optimal blank shapes. It accounts for material stretch and deformation and is specifically designed for estimators, engineers, account managers, and tool and die designers. Blank Size Engineering is a powerful nesting software specifically designed for nesting sheet metal blanks on coils. It automatically calculates the best nesting layout to optimize material utilization based on coil width and pitch constraints.

Blank Size Engineering is widely used for estimating blank size, along with blank nesting for maximum material usage, scrap & piece price. The plug-in is used to predict thinning, thickening & also to generate a forming limit diagram.


One Step Blank Development is a very useful tool for cost estimators, engineers, sheet metal product designers and tool and die makers.  It quickly generates an accurate blank profile for the sheet metal part using a 3D model. It simulates material behaviour during forming and reports manufacturing feasibility and requirements.

For the estimator a quick blank representation can be achieved in minutes to highlight potential manufacturing problems, determine material costs and to streamline the production process. The designer can benefit from the quick analysis to determine areas of a component design which may need to be modified to provide lower manufacturing costs. For the toolmaker, the application is invaluable for identifying areas of a component that will require changes or complex / multiple operations.
Dynaform accurately predicts flat blank profiles and supports tailor welded blanks & double attached parts. The output of press direction can be generated automatically, flanges can be unfolded and trim line calculated.

Blank Size Engineering includes an industry proven solver (MSTEP) for the accurate prediction of flat blank profiles from 3-D part geometry. Designed for cost estimators, blank predictions consider both linear bends and the material stretch that occurs during the forming process to produce the most accurate blank possible.


The Blank Size Engineering module provides for 1-up, 2-up and multiple blank nesting. The material usage and fall off is calculated along with piece price. Minimum required blanking tonnage is estimated. Nesting optimization can be performed to calculate the best material utilization.


Automatically generate reports for cost estimation and quotation of the part material. Report output includes detailed descriptions of overall blank size, nesting configuration, pitch, coil width, material utilization, number of coils required to meet annual volume and total piece price for materials.
