Primitives and Operations are free to use. For Parametric models, you can get a passcode here:
How to create something? There are two models you can see in the viewport: one is passive, and the other is active. The passive model can be modified by the active model. When you create a new primitive model, you can choose the mode (passive or active) by clicking the checkbox labeled 'm1' or 'm2'. You can shape the passive model by using boolean operations (difference, union, intersection) with the active model.
Important:
Some operations take more time, so please be patient. If you're experiencing a very long delay, wait a few more seconds, then click the reset button in the top-right corner of the viewport or reload the page and repeat the operations.
We clean the server-side storage every 15 minutes, which may cause the deletion of any model you are working on and have left untouched for 15 minutes.
We don't save the current state, so if you reload the page, you will need to start modeling all over again.

File exports:
The modeller supports two file formats for exporting: .step and .stl. The .step file format is editable in other modeling software, while the .stl format is commonly used in 3D printing.
