User Guide
Everything you can do in yucad3d — the commands, the design workflows, and the engineering behind them.
Get oriented
Getting started
Create a project, draw your first alignment, see it in 3D.
The interface
Tabs, ribbon, Object Browser, Properties, docks and the status bar.
Design workflows
Horizontal alignments
Tangents, circular curves and clothoid spirals; draw, edit, offset, fit.
Profiles
Vertical alignment: ground line, design grades, VPIs and curves.
Superelevation & widening
Curve banking with gradual runoff, and pavement widening.
Surfaces & volumes
TIN surfaces from points or corridors; breaklines; cut/fill.
Points (COGO)
Create, import and compute survey points.
Assemblies & Composer
Build cross-sections with the flowchart Composer and the library.
Corridors
Sweep assemblies along alignments; regions; corridor properties.
Sections
Inspect the cross-section at any station.
Utility networks
Water / sewer / storm networks with built-in EPANET + SWMM hydraulic analysis.
Transmission lines
Overhead power lines: parametric towers and conductors with catenary sag.
Project setup & reference
Design standards
AASHTO, RAL, VSS, KGM — and how they drive the design checks.
Georeferencing
CRS, grid vs ground, scale factors.
Collaboration
Central-model worksharing and change history.
Layout
Paper space, sheets and viewports.
Command reference
The full menu/ribbon command list in one table.
Formula reference
Every engineering formula the program computes, with variables.
