Parametric Structural
Detailing Reimagined
An advanced suite of open-source engineering tools for generating accurate Bar Bending Schedules, DXF exports, and detailed structural designs instantly.
Seamless AutoCAD Integration
Downloading DXF files is just the beginning. We provide a lightweight AutoLISP companion script that bridges the gap between RDCAD Express and your local AutoCAD environment.
- ✓Instantly imports your most recent download
- ✓Attaches block to cursor for immediate placement
- ✓No file-browser navigation required
Copy CAD Command
Say goodbye to downloading and importing files. Use the Copy CAD Command feature to instantly grab the LISP script of your structural element, and paste it directly into AutoCAD.
- ✓Generates drawing instantly at your cursor
- ✓Completely eliminates file clutter
- ✓Faster than standard DXF exports
Tested & Reliable Core
We know that structural detailing requires absolute precision. That's why the core mathematical engine and DXF generator of RDCAD Express are backed by a comprehensive Vitest test suite.
- ✓Rigorous testing for accurate BBS calculations
- ✓Automated validation of generated DXF structural integrity
- ✓Deterministic outputs across different environments
