Use cases 

To be able to use anthropometric data in the design process, we created the 3D HUMAN MODELS. With these models, the designer has great insight into the size and volume differences. Especially when different models are put in the same pose and made semi-transparent.

Car Seat Development


SLIMDESIGN set out to improve the way we travel with babies. During the analysis, they came to the conclusion that there is a contradiction between the crash safety and the ergonomics. With this car seat system, they aimed to resolve this contradiction and trigger a meaningful innovation in child seats. See more project details on the SLIMDESIGN website.

Validation tool

The 3D Human Models can be used to validate the product design during the 3D CAD stage. The Child Restraint System Models can be used to validate the seat design and create clear documentation. It can be submitted to the homologation body to support the claim that the designs apply to the regulations.

Scaled rapid prototypes

The 3D Human Models can be positioned in any pose and 3D printed to scale. It shows the human interactions and gives the object a size reference.

The interaction between the product and its user can be visualized and used in presentations and user manuals.

User manual

Model body parts and joints

Model manipulation I Modeling strategy

Start with the bigger body parts and then position the extremities. Details like the hand and foot are the last step of the positioning. After you reached the desired position of a part, right click and set it to ‘Fix’. This will sometimes over-define the assembly for the time of the positioning but will disappear as soon you set this part back to ‘Floating’.
Note: Please make a back-up if you want to return to the original position after editing the posture. 

Left mouse click and move
to tilt the body part

Right mouse click and move
to pan the body part

Model manipulation I Controlling body parts in detail

In order to simplify the modeling process, most body parts move freely and can be directly manipulated by clicking and dragging them but fine details such as ‘trunk movement’. Hands and feet are controlled by adjusting mates. The mates can be found at the bottom of the model tree of each main- and subassembly. 

Under the body folders, you can open ‘mates’ in which the folders sorted to the body parts. Adjust these mates for complete control over the 3D Human Model. The folder ‘Joints’ contains the mates that hold the body parts together. Do not change these!

Model manipulation I Detailed manipulation

To edit the sub-assemblies from within the main assembly:
1) Right-click the sub-assembly you want to change
2) Select ‘Edit assembly’

Model manipulation I Within another assembly

1) Use the Insert components’ to add the 3D Human Model into your assembly
2) Move and rotate the pelvis into the correct position
3) Fix the model by right-clicking the assembly and pressing ‘Fix’

Model manipulation I Within another assembly

To move the parts within an assembly, the model needs to be set to flexible:
1) Right-click the model and select ‘Component Properties’
2) Set ‘Solve as’ to ‘Flexible’

3D Human Model can now be manipulated as described before. 


Student version 

If you would like to obtain the student version free of charge (students from affiliated educational institutions receive a free download code), please let your teacher or professor place a description of the tool and a link to on an open part of the education website. If the link is operational we will provide a free download code for all the students.


Over the years several different people have contributed to the development of the 3D Human Model. We would like to especially thank the following persons for their input and effort: Chris Spaander (who created the latest version), Nico Peet, Maria Hock, Marnick Menting.
Dr. Johan F.M. Molenbroek, Associate Professor Applied Ergonomics at the Delft University of Technology for his support, scientific input, and validation.


SLIMDESIGN is a well-known design studio from Amsterdam. They developed this tool to integrate antropomatric data in their development processes. They put the tool online, so others developers can also benefit from their work. The created funds are used to improve the tool. The latest development (on request of sponsors) was to increase the usability to CATIA, CREO and NX.  

Contact & support

SLIMDESIGN (the developers of this tool) is a well-known design agency with specific knowledge how humans interact with their surroundings. We would be happy to help with, for example, product development (our core activity), ergonomic validation, visualizations, FEM analyses, etc. If you have a special request for specialized models, rapid prototyped scaled and 1:1 models, scanned 3D faces/body’s, etc. please let us know. Please contact us by sending an e-mail.
