3D printing as a relatively new technology still has a relatively close representation in modelling software. These are predominantly still specialized in mechanical engineering parametric modeling, since 3D printing is still a small segment of the market.
Together in short, we go through what types of modeling software are available on the market, what they offer and how to choose the right one for us.
There are basically 3 types of spatial modelling software:
1. Volumetric Parametric modelling,
2. Surface modelling,
3. Free modeling.
Volumetric parametric modeling
Conventional methods of production (such as turning, milling, drilling, etc.) are based on simple geometric shapes such as semi-finished rods and ashlars. For these technologies, volume modelling is mostly the best choice because of its simplicity and the possibility of a shape uniquely curved for production.
It also has a great advantage and is parametric modeling, which is in short that changing one parameter is automatically updated and reflected in all phases of the model or report. E.g. When we adjust the length of the model, and the position of the hole is firmly defined, it will be adjusted automatically as well. This change will also be reflected in the report on the drawing.
In practice, various kinematic analyses in reports are also used for these types of software, as it is possible to uniquely define the marginal conditions.
Fence Modeling
With 3D printing, we are far from technologically limited. Complexity has hardly any impact on the price of production. Therefore, it prefers to be flat and free modeling in the space, like when we shape from a piece of modelling clay, there is no limits to the imagination.
In this modelling it is Possible to create shapes complex surfaces. They can be easily shaped, such as the wing of the aircraft or the hood of the car. However, the output is individual surfaces that need to be closed before 3D printing to make a volume.
While modeling complex shapes is considerably simpler than in volume parametrical modelling, the dimensions of the shapes are difficult to define, which may result in the product being unable to perform the required function after production (because of the uncertainty of the model).
Typically, changes are not parametric, so when we create a change anywhere in the modelling process, it may not be updated properly.
Free modeling
Sometimes referred to as organic modeling, just because of the similarity of geometric shapes with nature (trees, rocks, sea sasks, etc.).
The advantage may be the possibility of connecting with a tablet or special modelling hardware operated by hands, allowing for better and more accurate movement in space.
For 3D printing, free modeling is the most appropriate optionif we shape organic or other heavily definable shapes. It is possible to achieve extreme shape complexity and to unravine objects other than 3D printing inseparable.

Summary:
There are dozens of professional software for 3D modeling on the market. It is advisable to first match the production technology we will predominantly model.
Further, what are our experience with 3D modelling and, last but not least, the budget. The license for a top-notch modeling software can be moved up to tens of thousands of euros.
The good news is that there are also free software that can achieve quality results.
