Model Airport question

Hi everyone, I am currently making a model airport of CYYZ in 1:400, I am going to 3D print the terminal and I design in tinkercad. Does anybody else know any free designing software? I want to be able to further my horizons!

I am not familiar with this topic. I don’t know exactly what you mean by that either.

The only software in this topic that I know of is GitHub. IFAET also uses this software for their airports, as far as I know. If you have any questions, feel free to put them here. Here is a link:
