Design once. Adapt forever.

Geometry is driven by parameters

Not manual edits. Change a parameter and connected geometry updates instantly.

Parameters can be simple values or formulas

Use Excel-style formulas to embed engineering rules and calculations.

One block definition supports many variations

Build once, use everywhere with different parameters.

Who LogiDraft is for

Engineers creating repetitive 2D layouts
Teams maintaining standardized drawings with variations
Electrical, mechanical, HVAC, and industrial designers
Anyone tired of redrawing the same details over and over

This goes far beyond layout

LogiDraft blocks can embed real engineering logic—automatic transformer sizing, motor protection rules, conditional geometry, and more.
Explore these deeper examples in the Help & Documentation.
