How can I minimize thrash when I present technical designs for my projects?

How do I get better at technical design review and presentations? I go into these tech review meetings and get a ton of questions from senior engineers that aren’t directly related to the project and the raw volume of questions derails the whole thing. It always feels like something is missing. What should the preparation phase of a project look like?

Adding on to this, I do go into these meetings with a technical design document. Ideally people will comment on that well before the meeting, so we can get more of the discussion done async. However, people often don’t have time so they don't do this, making the tech review meeting the first time they see the tech planning materials, hence all the questions.
