I’ve been thinking about this while looking at a project like BitumenCalcPro, where users work with technical numbers such as asphalt volume, mix percentage, density, and material quantities.

Good visual design can make this kind of information much easier to understand. Things like typography, spacing, icons, and simple diagrams can help users quickly understand the results without making the interface feel crowded.

For those using Illustrator for technical or data-heavy projects, what design techniques do you find most useful for keeping information clear and professional?
