Surface reconstruction and tool correction

Do you want to create CAD models quickly and simply from polygon meshes or point clouds? Or do you want to reduce tool optimization iterations in mold making and improve your CAD data for additive manufacturing?
All this is possible with ZEISS REVERSE ENGINEERING. 


Interactive in a guided workflow

Highly precise – even in case of sophisticated freeform surfaces

On this page, you learn how to create CAD models for components with ZEISS REVERSE ENGINEERING. To correct CAD data of tools and printed parts, go here to learn everything about the tool correction option.

Powerful surface reconstruction software

Scan a component in ZEISS INSPECT or any other software and import your STL or PLY data and ASCII formats into ZEISS REVERSE ENGINEERING. Just a few guided steps result in a highly precise CAD model that you can export into common formats such as IGES, STEP or SAT.

What you can expect

System independence

System independence

It makes no difference if you create your STL data with a 3D scanner, an X-ray CT system or a coordinate measuring machine. ZEISS REVERSE ENGINEERING is capable of importing measuring data from any given measuring system.

Guided workflow

Guided workflow

ZEISS REVERSE ENGINEERING guides you interactively and step by step through the CAD modeling and the tool correction. This will considerably reduce the training expenditure.

High precision

High precision

Import any number of raw points from your scan data – there are no limits at all. This is how you create highly accurate surfaces.

Large functionality set

Large functionality set

Edit your measuring data with practical functions for STL data, such as filling holes or smoothing surfaces. Afterwards, you can combine or blend the newly created CAD surfaces, add chamfers or radii and apply Boolean operations or volume functions (extrusion, lofting, sweeping). The result is a solid CAD model.

CAD models for any conceivable shape

Geometrical parts

Powerful functions for components with standard geometrical shapes: Export your data into ZEISS REVERSE ENGINEERING and get busy creating, combining, extracting and adjusting them. The software guides you through the entire process – until you achieve exactly the result that you want.

Freeform surfaces

ZEISS REVERSE ENGINEERING offers various functionalities for achieving highly precise freeform surfaces. For instance, use “Surface approximation to points” when converting your data, and let the software guide you through the process step by step until your component has been created.

Organic shapes

The software is equipped with special engineering tools for accurately remodeling flowing, organic shapes. The best thing about this is: It takes only a few clicks from importing the scan data to the complete 3D model – even in case of sophisticated object designs. Watch this video to see how it works.

Even faster to CAD thanks to 2D-Sketching

The new feature saves you even more time when creating your CAD model - especially when it comes to complex geometries. The principle of the sketch function: Sketches are created in sectional planes, which are optimized by defining dimensions and constraints. In the final step, bodies can then be created from the sketches simply with a mouse click.

 A seamless workflow is possible with the ZEISS INSPECT inspection software.

The metrology software by ZEISS is united in a central platform: the ZEISS Quality Suite. Providing an uninterrupted data flow, it accompanies you through the entire workflow.

What does that mean in the field? If you collect, optimize and align your scan data with the help of the ZEISS INSPECT inspection software, you can transfer the processed data to ZEISS REVERSE ENGINEERING with one mouse click. It automatically creates a new project, so that you can start with the CAD modeling right away.
