3D CAD Designer
Need a 3D CAD Designer ?
If you have been looking for a 3D Cad designer please give me a call.
I started work as a design draftsman in 1979 and began as a CAD Designer using version 3 of AutoCad in 1984. Drafting on the computer was a labour saver mostly in the way it enabled the designer to make changes easily to whatever design they were working on.
However, you still needed to learn a lot about about how things were built in the shop or out in the field to really do a good job in using the computer to make easy to understand drawings that ultimately made items easier to build.
In 2004 I had created www.aaadrafting.com and had been using that domain and website for the past 20 years. As I build this new website, i plan to move much of the content from aaadrafting.com here.
My experience in wastewater processing includes the design of vertical oscillating plate mixers for Egg digesters and other types of large liquid slurry vessels. The slow cyclical up and down motion of the mixing disc makes this kind of mixer ideal for large vessels where the cost of operating propeller style mixers is prohibitive.
For many years I worked making fabrication drawings for incinerators for a company that built highly portable shipping container based incineration systems. These systems required refractory design and fuel systems for oil burners to enable the compustion of multiple types of fuel.
I have designed and built dust collectors all the way up from cartridge collector units all the way up to huge industrial baghouses with all the associated ductwork and pick up points
Dust Collection
I've worked on dust collectors from bin vents to cartridge collectors through huge baghouse collectors. As a 3D Cad designer I had to learn OHSA and local building codes to design safety compliant stairs, ladders and platforms that are frequently used with dust collectors and many other types of storage tanks and vessels.
Incinerators
My experience has included batch incinerators up to 5 tonnes as well as continuous flow incinerators. I have worked on multi fuel burners for the primary and secondary chambers and exhaust stacks with particulate monitoring equipment
Duct Design & Piping
For duct design I like making use of the predesigned duct components made by NordFab but I can design any size duct fittings including elbows, spools and wye's and make balanced systems using the ACGIH spreadsheet calculator.
I can design pump skids using filter housings, flowmeters and monitoring equipment of all types of descriptions and can do pipe spool drawings based on ease of assembly for the pipefitter.
Architectural
My experience is in fiber cement, porcelain and copper cladding including various girt systems used to attach cladding panels to the building structure. I can do hatbar and angle systems in Z275 galvanized steel or work with proprietary systems such as Agrob Buchtal's steel hangers.
As a 3D Cad designer I can unwrap all the views of all the elevations in a cladding system from estimating documents and do all necessary head, jamb and sill details for doors and windows.
The glass railings page shows stair and glass handrail projects I have worked on and lays out some of the problems and solutions for jobs like these
Structural
In working with dust collectors and stair towers I have created a lot structural steel supports with associated bracing, top and bottom plates to CISC and AISC specifications. I can do bolted or welded connections and foundation plans with grout and embedded fasteners.
My experience started just out of high school in 1979 on the drafting board with mechanical pencils, Leroy ink stencils, mylar sheets and stinky ammonia filled blueprinting machines.
I was spared the slide rule by being just in time for the introduction of the handheld calculator which got used for weight calculations and trigonometry. Good old Pythagoras helped me layout plenty of angled steel braces.
In 1981 I graduated as a Mechanical Technologist and by 1983 had my first experience as a CAD operator. Back then you needed a seperate program to print drawings from AutoCAD and the state of the art was a wide format pen plotter.
Still it was a great to ways to automate repetitive tasks and I no longer had to struggle to make my lettering perfect, I had a 640K IBM PC to do it for me.
AutoCAD eventually made its way to the microsoft windows world and things contunued to get easier. It was 2002 before I got my first chance to learn hands with SolidWorks at a year tool and die design night course in Hamilton, Ontario.
Most of my experience has been as a structural drafter and mechanical designer. My work has included steel buildings, mezzanines and support structures for large material handling equipment.
I have had experience as an doing electrical draftsman too. That work included electrical ladder logic diagrams, P&ID drawings and schematics of various types.
In 3D modeling I have made parts, assemblies and weldments. I consider myself pretty good with multi body parts such as welded assemblies. The multi body environment makes it really easy to process revisions as opposed to just plain assemblies of parts.
As well I have done animation of assemblies as well as a lot of conversion between AutoCad and SolidWorks, setting them up to make sure they get along nicely together.
There is still plenty to do in the world of technical drawing despite the perception that computers can do it all nowadays. Not so, the computer is only as good as the person who is working it. "Garbage in - Garbage out" as they say.
Talking with the machinists and welders and taking pains to present your fancy computerized work in a way that makes their life easier is what its all about. You are the scribe that provides the documentation for the team, makes no difference if your tablet is made of stone or silicon.
As a draftsman, designer and CAD operator I can design your next project. With more then twenty years experience from the drafting board to AutoCad and to SolidWorks 3D modeling.
