DCT - Die Configuration Tool
Die geometry & nib assist
Free
Design drawing dies on iPhone, iPad, and Mac. Live cross-section, nib assist, dimensioned reports, and DXF export to CAD — fully in sync with the DCT web app.
DCT (Die Configuration Tool) is the native macOS, iPad, and iPhone companion to United Die Company's web-based die design tool. It lets die engineers and customers configure extrusion and drawing die geometry and instantly see a precise, dimensioned 2D cross-section.
Enter your incoming and finish sizes and adjust the die parameters — bell radius, approach extension, approach angle, blend radius, bearing, and back relief — and DCT renders the die profile in real time, with the proprietary geometry and nib-assist calculations handled by United Die Company's servers.
Key features:
Live 2D die cross-section that updates as you change parameters, with pan and zoom.
Nib Assist: see the minimum nib, current vs. required nib height, maximum hole, nib OD, and percent area reduction — with at-a-glance warnings when a configuration falls below minimum.
Full dimension readout: nib height, bearing, blend height, approach height, stock height, and OD, with one-tap copy.
Layouts that adapt: on iPhone, narrow iPad windows, and Split View the drawing takes the full screen, with panels available on demand.
Export DXF: generate a layered CAD drawing of the die profile with true arcs, ready to open in any CAD package.
Design Library: save, search, and reload your die designs, synced privately across your devices via iCloud — with automatic backups you can save, restore, and merge.
Manage Backups: save, restore, and merge your Design Library backups
Save and load design files that are fully interchangeable with the DCT web app.
Print a clean, dimensioned one-page report with a print-optimized color scheme.
Service status at a glance, with optional email alerts if DCT cloud services ever have an outage.
Built-in illustrated user guide, plus preferences for color themes, per-line styling, and display options.
DCT requires a valid United Die Company access code and an internet connection. Access codes are provided at no charge — there is nothing to purchase in or outside the app. Current United Die Company customers can request an access code, and prospective customers can request a 30-day evaluation at https://udico.co/dct/dct#dct-application. For access code questions, contact dct@udico.co.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Version 1.2 refines the drawing view and the Design Library:
- Fit to Viewport now frames every die properly and re-fits when you
rotate, resize, or use Split View
- On iPhone and narrow iPad windows the die draws much larger, with
dimension labels sized to the screen
- iPad: in narrow layouts the Parameters and Nib Assist panels open
on demand instead of squeezing the drawing
- The app remembers which library design you're working on, so
reopening keeps its details and saving updates the original
instead of creating a duplicate
- Blend Radius now displays as a radius, matching how machinists
read it
- Exported DXF files record the app and version that produced them
