Workflow

Physical part 3D Scan 3D CAD design

Different approaches for modeling

When going from a 3D scan to a 3D CAD design, there are in general 3 different approaches on how to create the surfaces. We will always work closely together with you and discuss what you will use the model for. In this way we can determine the best way for creating your 3D CAD design.

Type of Reverse Engineering	Auto-surfacing	Geometric modeling	Freeform modeling

Main use	For reference when working with stl file is not possible Organic objects, without geometrical features	Reproduction of geometric parts Get the original design	Reproduction of freeform parts Sharp edges
Features	Very accurate and fast Sharp edges get lost Complex models with lots of surfaces Translation errors between softwares possible	Very clean model Flat surfaces and perfect radii Easy to make adjustments in other CAD programs Design intent	Clean model Nurbs surfaces Relatively easy to make adjustments in other CAD programs As-Is

Auto-Surfacing

“The software calculates the geometry in an automatic way”

Very Accurate
The model consists of small high degree nurbs surfaces. These surfaces have the ability to closely follow the original mesh. Therefore the 3D CAD design will be very close to the original scan and physical part.
Quick results
The 3D CAD design is built by an automatic surfacing function. There are limited options available to change the settings in order to improve the result, but the biggest advantage is that the model is generated relatively fast.
No details and sharp edges
Because of the fitting principles and the fact that all the surfaces need to be tangent to one another, small details and sharp edges will get lost. So if your model has sharp edges we will use one of the other or a combination of multiple methods.

Geometric Modeling

“Using perfect planes and radii”

Very clean model
Since we only use geometrical shapes, the resulting model is very clean and will have a small file size.
Highly compatible with other CAD software
This type of model can be loaded in every CAD software. With boolean operations the part can be changed and adapted easily.
Accuracy depending on the part
Since we only use perfect geometrical shapes with this method, there might be a bigger deviation to the original part. For example when there is a dent in a flat area of the part. In the model we will use a perfect plane, so the “dent” will be removed.

Freeform Modeling

“Using clean and smooth nurbs surfaces”

Clean model
There will be some nurbs surfaces in the result but they will have a low degree of complexity. This keeps the file size and the room for translation errors also to a minimum.
Aesthetical freeform models
When using this type of nurbs surfaces we are able to catch the shape of freeform object. This would not be possible with the geometrical approach.
Longer modeling time
With this method it is often a matter of trial and error to get to an accurate and clean result. This makes that it is more time consuming than the other methods.
