Most Frequently Asked Questions

What is ICEM Surf?

ICEM Surf is the ideal CAD Software tool for all free-form surfacing tasks and visualization. It is intensively used in the automotive industry to design car bodies and interior parts. Although specialized in automotive Class A surfacing, the range of applications also includes manifold surfacing tasks in automotive body-in-white and press tool design as well as Industrial Design of consumer goods and high-end visualization with newly developed Realtime rendering technology. Surface quality checks and manufacturing feasibility issues are addressed with various static and dynamic surface diagnostics. ICEM Surf excels in the area of reverse engineering with robust functionality to painlessly handle the input of digitized physical models in a fraction of the time required by other systems. ICEM Surf includes direct interfaces to a variety of direct interfaces to major CAD/CAM systems like CATIA, Unigraphics. With these direct interfaces plus standard CAD interfaces such as IGES, VDA/FS, ICEM Surf fits easily into any CAD/CAM environment.

How do you create surface models with ICEM Surf?

You can create surfaces from a variety of initial situations:

  • Start from scratch
  • Start from a 2D sketch
  • Start with Input from digitised physical models via touch probe
  • Develop surface models from ordered or unordered (point clouds) digitised data
  • Import geometry from existing CAD models (direct translators are available for Pro/ENGINEER, CDRS, CATIA, CADDS, I-DEAS Master Series, and Unigraphics)
What distinguishes ICEM Surf from other surfacing packages?

Most surface modelling packages allow only approximate control over the shape and quality of surfaces. ICEM Surf allows precise direct control over all surface attributes and displays the current surface characteristics dynamically as you make changes to your model. In addition all surface diagnostics (sections, reflection lines, etc.) that help to analyse the current surface quality are dynamic and associative.

Direct dynamic surface modelling can be done in colour shaded display mode (highlight mode) and in stereo mode. ICEM Surf’s Realtime Renderer allows you to model and evaluate your product in a realistic environment.

ICEM Surf provides truly productive global modelling features that allow designers to make changes that span many surface patches. These techniques support the rapid exploration of dramatic design alternatives without redefining the underlying surface model.

The unique scan modelling capabilities of ICEM Surf give access to innovative and more efficient shape definition methods in the product design process. Scans (point clouds) can be modelled and diagnosed similar to curves and surfaces in ICEM Surf. Virtual Clay Modelling has become reality.

If the entire design process is done in ICEM Surf, you work with precise data and surface quality from the very first beginning. This means that no additional work is required for improving data before you may carry out the next design step, saving your precious time.

Where does ICEM Surf fit in the design to manufacturing process?

ICEM Surf today has become a universal modelling system for surfaces and scans in all application areas, from Styling and Conceptual Design up to Tool & Die Design, via Visualization, Class-A Surface Modelling, and Engineering. This means that the entire design process from the first idea to the manufacturable product can be captured by one single application – ICEM Surf. Nevertheless, depending on a customer's environment, any other data input at any stage in the design process can be imported to ICEM Surf. Analogously, ICEM Surf data can be transferred into any other application further down in the process chain. For these systems, ICEM Surf is the catalyst or collaborator in this process supporting conceptual iterations, data models - coming from other industry CAS/CAD solutions - can be transferred to ICEM Surf for feasibility studies and surface evaluations prior to manufacturing. These surfaces can then be transferred to other major packages like CATIA V5 or V6 or through a direct or standard translator such as IGES.

What is "Direct Modelling"?

Direct creation of free-form surfaces from digitised data or from scratch without underlying objects. Surfaces are worked on directly without the need for a network of curves. Modifications are carried out directly in real time.

What is "Global Modelling"?

As the surfaces are directly manipulated, surface diagnostics like cross sections, highlights or split lines are dynamically updated. With ICEM Surf you always see what you get.

What is "Feature Design"?

When a design modification is introduced, engineers can use ICEM Surf's powerful Feature Based Modelling. This feature allows structural design elements that have to be matched to aesthetic surfaces to be automatically updated to a modified aesthetic surface.

What is "Reverse Engineering"?

ICEM Surf also has special functionality to painlessly handle the input of digitised models. Surface models can be developed from ordered or unordered digitised data in a fraction of the time required by other systems. Special diagnostic tools guide the user to form the correct balance between smoothness and adherence to the digitised data.

Can I use ICEM Surf along with other CAD design tools?

Yes, the default ICEMDB format is interoperable with CATIA V5 & 3D Experience Platform. ICEM Surf also supports IGES, VDA/FS input and output as well as direct translators to and from CATIA V4, Unigraphics.
