I'm an engineer working for a small manufacturing company producing several varieties of recreational vehicles. Along with a Mechanical engineering degree, I also have an AS in drafting and was a certified drafter until 2010 (upon exp.).
As some of my posts have reflected, we're experiencing the the uphill battle of expanding a small business. A major issue for us is technical specifications... We stock about 5,000 different parts at any given time. Probably 75% of those are purchased and the remaining 25% are fabricated. Almost 100% of the purchased parts are modified in some way except for fasteners.
Nearly any given part will require 3 or more of the following drawing types:
- inspection/receiving drawings: how to inspect the parts, how many (i.e. 5% or 100%) what to look for, what is/isn't acceptable
- fabrication/modification drawings: specify what is to be done to the part or what is needed. (25% of these drawings are meant for subcontractors)
- manufacturing process drawing: how to obtain the specifications shown on the fab/mod drawings; what tools to use, how to use them, what to be careful of, what to do, what not to do.etc
- assembly/kit drawings: how to assemble/prepare the sub-assemblies as required for inventory
- installation drawings: how to install the part, subassembly or kit onto the vehicle.
- service drawings: how to service/replace various parts. Exploded drawings as used by customers for ordering spare parts.etc
We are not big enough to order the quantities required to get special attention from our vendors. Often we are ordering wholesale in consumer packaging. For a given part, such as a light, we may order from 50 - 150 per year. The vendors often won't consider special orders until about 1000 - 2000/year.
With this being said, since we rely on out vendors for 75% of our parts, 3/4 of our inventory is "subject to change without notice". Documenting the changes is a full-time itself, when doing it in AutoCAD. Especially since many vendors won't give out drawings because they are proprietary.
Anyway... to the Point:
I am going to substitute technical photos in place of drawings when possible.
I'm looking for a software that will basically allow the user to make technical drawings using pictures... This would mean having a way to easily import pictures, add leaders, mock-up dimensions.etc
I've tried this with AutoCAD and it works ok but is not conducive to the process.
MS paint takes too long to create leaders and dims and will end up looking like a kindergarten finger painting if you're not careful.
See the attachment. The "photo" drawing took less than 1/4 the time of the "CAD" drawing.
This may not be the prettiest solution or the most professional but there aren't many other options. Hiring more drafters is out of question at this point. It also has advantages because many of the workers are not trained in blue-print reading and therefore can much more easily relate to pictures. A picture is worth a thousand lines.
I figure that this problem & my proposed solution cannot be unique to us.
I would of course continue to produce proper drawings for anything that is going to a sub-contractor.etc
Any input will be appreciated.
