How I transformed myself from a novice to an amateur FreeCAD modeler ?

To introduce myself, I am a sophomore university student studying biotechnology in Lithuania. Owing to my ardent desire and passion in science, I approached Professors to allow me to assist them in on-going projects but with no avail. Obviously, I realize now that I had been too much ambitious but fortunately, a junior researcher recognized by passion to try something new and decided to take me under his wing. This particular project involved modelling a mini-incubator and that’s how I stepped into the world of parametric modelling.

I will explain how I improved over time and will offer some tips for faster progression.

I use FreeCAD v0.18 (with add-ons). I know it is not the best 3D modelling tool out there and is under active development but it fulfills my requirements.

Here we go!

5 tips I wish I had known when I started learning FreeCAD:

1. Familiarize:

Firstly, learn how to rotate your model and how to hide/unhide your operations. Also, be familiar with the attributes of your solid/sketch. Mastering the placement tool for sketches (after deactivating the map mode) is beneficial in the long-run.

2. Be imaginative:

Perhaps, sometimes the process is more enjoyable than the outcome.

Science is a way of life. Science is a perspective. Science is the process that takes us from confusion to understanding in a manner that’s precise, predictive and reliable — a transformation, for those lucky enough to experience it, that is empowering and emotional.

3. Know your outcome:

4. Be keen on geometry:

Parametric modelling is the creation of a digital model based on a series of pre-programmed rules or algorithms known as ‘parameters’. Knowing how to work with the parameters is one of the basic skills of a parametric modeler.

Be clear with the constraints you apply for your sketches and ask yourself ‘why’ every time. Being clear with planes is crucial.

5. Play around:

These are the 5 tips I want to offer for those who are considering to work with FreeCAD.

A bit of a back-story here 😁. I started off from basic models like these:

To modelling more complicated models like these:

PS- The last one is my bottle cap!
