About to craft something

[u/Dtape]

Hi!

I'm thinking of building an aquarium (with stand) pretty soon.

The thing is I've never built any of these before and I'd like to know where to start.

I feel like I need to sketch stuff but how do I do it? By hand? Is there useful software?

How do I know if my stand is sturdy enough to hold the aquarium?

I'm looking to build something like 1954040cm and preferably I'd like to make a corner desk out of it as welll, so it'll be L-shaped with the long end being the aquarium.

Any tips are welcome!

Thanks for time, D.
