DELCAM has been granted a UK patent (Patent No. 2 389 764) for its unique Total Modelling method for adding logos, textures, styling details and other decoration to CAD models. Delcam is represented in Australia by Camplex Pty Ltd .
Successful applications of the technique already include the development of packaging, footwear, ceramics and toys, and many other products where complex decoration can add value.
Total Modelling moves beyond conventional solid and surface modelling by bringing together elements of Delcam's Power Solution software range in a unique, fully-integrated combination of CAD design, reverse engineering and triangle modelling methods.
This wide range of techniques gives designers the ability to create innovative products more easily and more quickly, without any restrictions to their creativity.
Total Modelling enables triangle models, including those generated within the ArtCAM engraving program and the CopyCAD reverse engineering system, to be incorporated into surface or solid models created in Delcam's PowerSHAPE hybrid CAD software.
This close integration means designers can move between the different types of modelling more easily and see more quickly the effects on the overall design of any changes in a single element.
The patent granted covers three key aspects of product design with CAD. Firstly, it covers the ability to create a solid model that combines parametric surfaces and facetted reliefs, such that the resulting model is watertight.
Secondly, it covers Delcam's unique embossing method based on wrapping using texture mapping. Thirdly, it covers the ability to represent the embossing as a solid feature, such as when the underlying surfaces change the embossing and it is re-wrapped and re-trimmed.
Total Modelling enables logos, textures and other decorations to be incorporated into product designs more readily to help reinforce branding.
It also means any subsequent changes can be completed more quickly, for example when updating a design to be used in merchandising for a new television or film promotion.
The use of Total Modelling is both more flexible and more powerful than the Boolean addition techniques used in most CAD modellers.
Total Modelling also enables the addition of styling features to products ranging from automotive exteriors to domestic appliances.
In the automotive industry, different body styling of both decorative features and functional items, like air intakes, can be incorporated with an exact match to the underlying bodywork.
The size, position and design of these features can be changed in seconds, rather than the hours that would be needed with conventional CAD modelling techniques.
In a similar way, both decorative items and functional textures, such as grip surfaces, can be added to designs for electrical equipment that needs to meet both aesthetic and practical requirements.
Total Modelling can also be used for any bespoke items, for example, footwear, medical devices, prosthetics or sports equipment.
Design data specific to the individual customer or patient can be captured by reverse engineering and then used to modify a general outline design to any particular requirements.
