Hi all,

Wanted to add CAD topic,

heres a quick picture

Will update

SparWeb · « **Reply #1 on:** December 22, 2020, 05:42:44 PM »

That's a topic that triggers my attention.

I have about 15,000 hours experience in AutoCAD, starting in R13 in the 1990's and continuing to this day with the latest and (somewhat) greatest.

There is still so much that can be expressed and created with a 2D drawing. Skill is being lost, and certainly is respected less and less. I still do drawings as if they will be printed on paper. Below, the drawing was done with the "large format" paper layou, where a large number of views are placed on the same large sheet space. It's intended to be printed on a paper at least 3 or 4 feet across, and convey the big picture of a complete assembly process in one place. This is very different from today's preferred design methods which attempt to describe a design or a work instruction with miniscule step-by-step instructions. I don't like treating the workers who use my designs like idiots, even though some have a way of insisting on being so.

I'm also pretty adept with Autodesk Inventor, having taken advanced modeling courses and then used it for many years at work. Eventually I was pushing the software in ways that even got Autodesk's attention but they really weren't interested in supporting what I was trying to do. I wanted to use Inventor like OEM's use Catia, but Inventor isn't really designed for that. But I was satisfied that I really was getting my money's worth out of what I had been taught and a rather expensive piece of software. Recently I've experimented with online CAD services like Onshape and found a very powerful system there, too.

My current workplace really only uses Solidworks, and just barely so. I definitely can't use SW at the level that I used Inventor, partly because I don't use SW often enough to get the hang of it, and partly because SW won't do everything I could do with Inventor. Part of the difference is actually the features package with each one. If you compare the Premium version of one with the bare-bones version of another, the contest isn't fair.

Well i tried to post here some drawings and finished products as i use TURBOCAD but my post does not go on. ?

Interesting subject.

I first starting using CAD around 1988 as my constructions got more and more complicated.

I use TURBOcad and its at version 14 now. I did think about AUTOCAD but it was never a straight transition.

What i find great with CAD is the transfer of exact dimensions to reality, especially making a new design of a Watch for instance.

Where in the old days of a big drawing board and pencil, and later finding out when scaled up or down if the 0.3mm dimension line is drawn so the centre is exact or not.

Transferring a CAD drawing to a building design is not much of an issue.

I draw in 3rd angle projection that is how i was trained all those years ago.

My Latest CAD has 3 dimension transfer and draw, but i really don't need that, as i tend to operate with folk that can understand a standard engineering drawing.

Nowadays i do take liberties by encompassing sections, and different scale snapshots all on one drawing, rather than a multitude of separate drawings.

Below is some of my drawings starting with a screen shot of my present CAD on a building here about to get restored internally. Other drawings are some of my Clocks and watches from design to finish product.

A clock design of mine for the Nation. this one of several drawings sent around the World to makers so that they could make individual bits they were happy with. Parts came back to the UK and assembled and then 2 clocks presented to the Queen and the Nation.

A pocket watch design, from the time of change from hand drawn to CAD, coloured in so normal folk can understand, and a New Clock design in preparation.

CAD changed everything, just so much easier to design and implement.

SparWeb · « **Reply #6 on:** December 23, 2020, 11:00:04 AM »

Clockman,
Now I know where you get your handle. Well deserved!
I spent an enjoyable hour this morning, poring over your clock drawings, thanks.

I have also just learned what Elinvar is. Thank you for that, too. Filed into a drawer in the back of my mind just in case such a thing is ever necessary or even of academic use.

From TurboCAD, I believe it has a native file format not very compatible with other systems, but can save to a more universal format like DXF.
For posting any kind of files other than graphic images, try putting them in a Zip file.

I have encountered this aswell, were working on it, if your files are jpeg they should work ok.

About CAD I have solidworks 2016 and Ive learned it was compatible with alot of other cad programs, neat stuff Im trying to figure out how to post edrawings files on the site.

clockmanFRA · « **Reply #8 on:** December 23, 2020, 02:14:01 PM »

Thanks SparWeb,

Hamilton only produced 1cwt of Ellinvar to their very special formula. At the time 1930s to 1940's Hamilton ruled the American manufacturers, and they even built a bespoke foundry and employed some very bright and intelligent hands on metallurgists.

In the Hamilton watches book, sadly only a few pages discuss the American Marine Chronometer and its special balance spring material.

Hamilton model 22 Deckwatches, (deckwatch was used as an auxiliary time piece and set from the Model 21 Hamilton gimbled marine chronometer for the navigator on deck to take a sight with a sextant). The 22 are highly sought after in the Watch collectors market that seek out mechanical precision timekeeping.

Yes, i can create DXF files from TurboCad, but small interior details get lost. However I re-draw the original drawing and allow for the width of the cut for fine laser cuttings with a CNC. I send DXF as an email attachment and then swing by when finished Pay and collect.

JW, Seems to be size, any JPEG over 1,4mb each does not post with other images even if they are a lot smaller.

I even ensured that my images stayed with the Fieldlines image post limits.

So i broke up my post to several and they were okay.

I use tinkercad lol and fusion 360 when I want to hack out a stl file from some ones work.
I love getting stuff off of grabcad and dropping into autocad and convert it to STL, than import into tinkercad and do my resizing cutting adding

Ya the CAD software is like our DVOM's I really like SW2000 because its easy to use I will have my setup soon. I have SW 2016 but I need to spend about 250 hours to become proficient.

taylorp035 · « **Reply #12 on:** December 30, 2020, 11:27:48 PM »

I've done a variety of detailed 2D drawings for school or work, but one the the larger assemblies outside of my rotary valve engine for my car was my senior year 15lb battlebot. 11k rpm and 4 lbs on the spinning hoop.... it was quite the sight to see spin up with the ~4 hp we had driving it and the #35 chain.

I think the most complex model was drawing the SAE Supermileage car. For the main body, it had about 70 section planes all lofted together with high accuracy for smoothness. 9 years later and I have yet to see someone else be able to draw a car like that... many people have failed trying.

JW · « **Reply #13 on:** March 30, 2021, 08:51:34 PM »

Well the project was a success

I got that old Optiplex 780 to run Win 2000, got the graphics card to work and the aspect ratio is correct now.

This thing runs like a bat out of hell compared with the 410 Workstation I started with. Love this program with SW I can draw off the cuff and its quick and easy. Flavio herd about this and he said what are you doing with 20 YO programs

. I do have the 2016 but really love the old one because its very easy to use.

Yaaaayy

Wow taylorp035 that is some really nice work...

JW · « **Reply #14 on:** March 30, 2021, 09:36:07 PM »

Hi Taylor got in to a little flurry there. I was a member of SAE for 5 years, first exposed to them at Ferris. After I left Ferris I went and took all 8 ASE tests passed them all in one testing session(1993). I have recertified as a ASE Master Tech several times over. I took the Advanced Level Specialist got 47 right out of 50 questions. For about 14 years I worked as a Process Engineer automotive related. I set up a remanufacturing plant that reconditioned aluminum alloy wheels. We used dual axis hydraulic tracers lathes (not CNC) and I did a bunch of other stuff there.

They are indeed workhorses ! The processor is 64-bit compatible too.

Cheers on getting 2000 working too

Thanks! We had to model everything since there wasn't much space in the robot. Every last cc of space was filled with 12 gauge wire when we were done.... partially because we decided to do separate 3s battery packs for each brushless drive motor and then wire them in series for the weapon motor for 6s. Needless to say, we lit a few things on fire in the cafeteria at school before we realized this also meant one of the 9 receiver wires had a ground at 12 volts and needed to be removed.

If you want to see really complex stuff, a production cylinder head or block print and CAD model is really impressive. But I can't share those prints

The new stuff with computer optimized shapes is even more crazy, but often times is not shown in detail on the prints.

Can you boot off an SSD.? My 2012 laptop sped up considerably with an SSD. I'd also max out RAM in an old system. It's limited to an unofficial 16 gigs of 1600MHz ddr3, but it's not for gaming so works fine for most tasks using Win10. I'd imagine 32 gigs is your system maximum. Win2000 can burn through memory even though it's 32 bit. Each process will snag its 4 gig page limit, especially in a CAD program. I would be really surprised if your program didn't support larger amounts as you can enable extended page sizes in high end software. You just have to change your boot.ini to enable extended memory bits before it's available. And even if it's not then Windows will use direct memory access to page swap which is 1,000 times faster than accessing disk space.

SparWeb · « **Reply #18 on:** April 01, 2021, 08:42:16 PM »

As long as your computer's BIOS will support a SSD as the boot disk, yes. And it's very likely to be supported unless the base motherboard is very very old. My 2009 system does that. Makes a FANTASTIC world of difference for just about everything.

JW · « **Reply #19 on:** April 01, 2021, 09:15:30 PM »

For this specific PC the 780 model you have to specify the SATA drive to boot from hard drive. I was also able to install on winXP pro.

JW · « **Reply #20 on:** April 01, 2021, 10:54:20 PM »

Having two separate partitions on one hard drive.

MattM · « **Reply #21 on:** April 02, 2021, 07:44:37 AM »

Pffft. Partitions are too uppity and new. True legacy don't need partitions. Pull out drives FTW!

Bruce S · « **Reply #22 on:** April 02, 2021, 02:30:59 PM »

The 780s can handle a SSD drive since you can get them as a SATA drive. Change the BIOS to ATA, it'll boot faster by several seconds. IF you add more than 1 drive of the same size it should even come up with asking you if you want to turn on RAID (depending on the BIOS version)
Dell/support should have the older and newest BIOS flash up to d'load no cost.

IF you go with several drives , you "might" need to look into upping the P/S, I was able to stuff 3 1Tb Spinning drives in mine by going with an external DVD drive, but the P/S started complaining. That's when I switched over to SSDs.
I also turned off all drive defragging on the SSDs <<<!!

IF you need memory for it let me know, I have some left over 4Gig mems from my unit at home.

Cheers

Im going to take you up on that... There seems to be 4 sockets and im only using 2.

I will send you a pm Ive still got tonns of the fieldlines bumper stickers, if anyone wants one just pm me.

Bruce S · « **Reply #24 on:** April 07, 2021, 02:27:40 PM »

JW;
No problem. Let me know the speed rating of those . I may just send you a matched set of 4.

PM me with a ship to add.

Bruce S

PS>>> The 780s can handle 16G. I know cause we had one doing ESRI calcs until we upgraded to a 9020 so we could overclock and get the Calcs down the less than a week of chunking away.

Cheers

should I proceed

Bruce S · « **Reply #28 on:** May 24, 2021, 10:09:08 AM »

See that part at the bottom where it says PC3-10600?
Match it with the same speed of the ones I sent.
OR faster of the ones I sent, just make sure the two you put in are one of the matched sets.
You should be just fine

.
Those are nice 4G sticks! Add a few more should get you up to a minimum of 12 - 16Gig.

Cheers!

Hi Bruce!

Everything went well with those memory cards, thank you... I only used 2 of them as you recommended and this has worked out great. If anyone wants some of them PM me there are plenty of them left.

Thanks again ALL.

MattM · « **Reply #30 on:** May 27, 2021, 05:39:50 PM »

DDR3 is a very common standard. You may yet find them useful.

You always pair them up, but quads are best with most DDR3 choosers. If you have 4 matching you may try it. You rarely have too much memory.
