Portfolio
These programs, written for a company that manufactures machinery for the mining and package handling industries, generate drawings or entire drawing sets of mechanical equipment in AutoCAD, directly from product order data. They do a lot more than that. This is a very brief overview
Integrated Suite of Mechanical Drawing Generation Programs
An example of the kind of engineering design calculations I can automate. This project took a few irreplaceable legacy design spreadsheets and used them as the heart of an automated system that doesn't design individual structural elements as they had to originally, it designs them all at once, nearly instantly! It was mission-critical because these spreadsheets, which were the most complex I have ever seen, were and still are the only method this structural engineering company had to accommodate the seismic code in Costa Rica. It creates beautiful design documentation in MS Access reports and it automates the drafting of the structural elements into AutoCAD as well!
Automated Rebar-Reinforced Concrete Structural Element Design and Analysis Program
A custom centralized payroll and accounting program I wrote for a company in San Jose, Costa Rica. It's awesome! They love it
Custom Payroll and Accounting Program
This program draws 3D ductwork with transitions, endcaps and boots. I wrote it as a proof of concept for an HVAC engineering company in Costa Rica. I adapted it from a 2D program I wrote years ago for my own design work. The important thing about it, other than that it works, is that it saves all the geometric and engineering data in the ductwork objects themselves which allows it to be modified, redrawn, and analyzed. The information can then be exported directly to the hardware that cuts the ductwork out of steel rolls.
Object-Oriented 3D Ductwork Program
I wrote this program for a structural engineering company in Costa Rica. Once again, engineers were trying to do something more sophisticated than the Excel spreadsheet they had cobbled together could manage, so I wrote a program in Visual Studio that freed them from spreadsheet tyranny!
Gantt Chart Based Engineering Man-Hour Scheduling Program
A description of the geometry, math and programming involved in automating the design of slew bearings in AutoCAD. The code could be developed further to include a ridge for the inner race to be glued together more securely, or make the the 3D printer tolerances variable (they're set to 0.1mm fit and 0.3mm slip). It includes a persistent dialog box which allows you to enter and modify the slew bearing's design parameters
Automated Slew Bearing Design in AutoCAD
I've automated my time recording and billing process to the extent possible. Cool Icon! Minimizes to the System Tray! Slick billing database!
TimeJournal - A project-oriented work timer with integrated journal and billing database
When I was a CAD manager back in the day, there could be big problems plotting out drawings for a submission, and I wound up writing some software to automate it and manage it better. I wrote a batch plotting program that was also much better than what AutoCAD offered, but I was particularly happy with the rewrite of the terrible stock AutoCAD plot dialog.
RocketPlot - A replacement for the terrible AutoCAD plot dialog, written in C++/ObjectARX
I wrote this program for an architect that opened up his own office furniture factory. It automated making cutting templates for the furniture designs.

Automated Architectural Construction Detail Generation Engine
A set of programs created for a startup company named Architectural Data Systems which automated the generation of architectural construction detail drawings for the projects of the clients of ADS. It consists of a program which allowed the data input of the data of every construction material or part used in construction in North America from lumber to roofing to concrete to cladding into a massive hierarchical database, a program that would allow the definition of architectural construction detail templates that those materials or parts would be inserted into, and drawn by the Architectural Construction Detail Generation Engine for inclusion into ADS''s clients' projects' architectural construction documents. This company was later sold to Autodesk. I was awarded 3 patents for this work, US Patent number #8,578262, #9,110,870, and #9,384,174
