including ".STL," commonly used by slicing software for subsequent 3D
printing. There is also the option to import external STL files or 2D SVG files to be

extruded and converted into three-dimensional models.

With these tools and through iterative processes, one can create almost any
shape. The limitation, given its focus on geometric primitives, might primarily

arise in realizing organic models (faces, statues, etc.), for which this software may
be less suitable.

Other Approaches to 3D Modelling
3D modelling has become an integral part of various disciplines, including
education, production, and research. Therefore, there are numerous modelling
software options optimized based on the desired shapes, the technologies used
for object production, and the broader field of application (engineering,

entertainment, medicine, art, etc.).

Tinkercad itself features a second modelling environment that allows the creation

of geometries through the use of block-based code programming:
CODEBLOCKS. In an educational setting, this facilitates the transfer of content
related to shapes, geometry, algorithms, and computational thinking. In a learning

context for adult learners, this approach can be very useful for introducing coding
and an algorithmic and parametric approach to three-dimensional modelling.
Among the various modelling software dedicated to 3D printing or digital

craftsmanship, especially in the educational context from high school classes
onward, and suitable for adult learners as well, the following are worth
mentioning: Autodesk Fusion 360 (https://www.autodesk.it/products/fusion-

360/overview?term=1-YEAR&tab=subscription#personal), Rhinoceros
(https://www.rhino3d.com/), and Sketchup (https://www.sketchup.com/). Some of
