This is a 2 to 1 ratio 2 speed planetary transmission. I have posted a crude version of it before but this has all the details. It is equipped with poly vee belt pulleys on the outer circumference of the ring gear and planet carrier.

Software used is SketchUp 7 with rendering in POV-Ray 3.6
Both programs are freeware.

Here's a SolidWorks model I made over a year ago while beginning to learn the software for work. It's based off the plans by Lou Blackmore of the Bentley BR2. Lots of small changes made including fixing geometry so it all fits together :rolleyes: and changing it to use all commercial bearings instead of the home made ones. It's not quite done yet, still have to do the simple nut and bolt hardware.

This is great, but I also am still in the 2D CAD world and would appreciate more discussion about the software used and the ease of learning and using it. Also, if it is capable of showing dimensions or at least has the ability to somehow measure distances in the finished, 3D sketch.

Certainly dimensions can be included in 3D rendered mode. They can be either conventional Dimension Lines or you can be a little more creative and include a measuring device. <grin>

This week I had to make a presentation to a customer concerning changes I would like to make to a device to satisfy our price and performance parameters but still fit within the space in the customer's assembly. They had not as yet released CAD models of the assembly, so the best I could do was print out several copies of a JPEG image the customer provided from their models. A little judicious application of scissors and tape, and I had rearranged the elements of the current component to resemble my proposed new configuration.

The snip & stick presentation turned out to be the most valuable part of the whole meeting.

I'd like to know how much ram you guys have on the computers running these 3d cad programs? I only have 2 gigs of ram and doubt my current desktop could keep up with these demanding programs.

Michael Moore
07-25-2010, 02:14 PM
I've got 4G with XP Home and a quad-core CPU. More RAM on your video card should help too.

I've been trying to practice modeling from some BSA factory blueprints and I'm finding it tough sledding with castings such as crankcases and cylinder heads. Locating bearings and motor mounts is easy enough, it is wrapping the "organic" castings around them that gets things really slowed down (and started over and over and over).

It doesn't help that the blueprints have a gazillion dimensions on them, and they'll show a couple versions of the same view but give a hole center on one view and the diameter of the hole on a different view. I spend a lot of time playing "find the hidden dimension." :)

I'm envious of the skill some of you have. I can usually get enough done of a simple part, especially one that is a straight forward milling/lathe job. But it doesn't always happen very quickly.

I've got both Alibre and Rhino and I tend to prefer to use Alibre for the parametric modeling feature. But Rhino does some things easier.

cheers,
Michael

Mine's a Mac running SolidWorks in XP via Boot Camp. System specs are 2.8GHz Core 2 Duo with 4 GB of RAM.

My old laptop ran SW ok. It was an HP with I think a 1.2GHz processor and 2 GB of RAM. It wasn't blindingly quick, but got the job done. That's actually the machine I did the Bentley engine on. Toward the end, with over 800 components in the assembly it did run a little slow. :D

Wasn't sure when I bought the Mac if it would handle SW. But it actually does very well, sometimes better than my PC at work.... The really nice thing about SW is they specifically allow users to install a legit copy on their machine at home. They figure you can't be two places at once, so the one license will cover both seats. Downside is the cost is pretty high compared to a lot of other programs.

Getting measurements is pretty easy. While in the part or assembly you can query the faces / parts and get a measurement. When you make a drawing it will get dimensioned just like any other CAD program.

One of the cool features of the 3D programs is you can get accurate weights, surface areas, center of gravity, etc. for each part or an assembly. I love working in it and hate having to fall back to our old 2D program (Anvil 1K) since we have so much legacy stuff at work. Some of it dates to the 1950's. Fortunately the stuff from the 30's was obsoleted a long time ago!

Evan
07-26-2010, 09:02 PM
I do. It's called Sketchy Physics. I am working on a black hole simulation but is is very approximate. Even the highest powered simulations fail miserably near the event horizon. The simulator math blows up as values approach infinity or zero as divide by zero errors cannot be avoided. The required resolution of numerical methods increases asymptotically.

You get to shoot a particle of infinitesimal mass into the black hole. By using a massless particle it simplfies the calculations near the limits.

I too have Sketchy Physics, but haven't used it yet since all my immediate needs are met with SketchUp. I am amazed that you can model a black hole. Although you do not have to consider collision detection, material elasticity, thermal expansion, etc., you do have the strong curvature of space itself. Very ambitious effort!

After viewing all these wonderful and creative images I want to take my computer and throw it against a wall.



I've been trying off and on for about a week to make a 3d image of a cog gear on Sketchup. Why sketchup? It's all we have at work. Why? Cause its free!

Evan
07-27-2010, 11:06 AM
Nothing wrong with free software. I will pointedly ask how many of the numerous online tutorials have you watched?

3D CAD has a steep learning curve mainly because the many little tricks that make it easy to use are not at all obvious. Tutorials are very valuable in getting you over the hump.

I sketched up some gears as an example. The total time to arrive at the finished model ready for rendering was less than 10 minutes. These images show the steps along the way in sequence:

I used a free involute gear plugin to make the gear. Time: ten seconds.

Then I pulled it into a three dimensional object with the push/pull tool and copied it in plan view to mesh them together.

http://ixian.ca/pics7/sketchgear1.jpg

I drew a circle centred in each one and pulled it to make a shaft.

Then drew a rectangle and pulled it for a mounting plate.

http://ixian.ca/pics7/sketchgear2.jpg

I stood it up with the rotate tool and drew a line across the bottom to separate a piece to pull out for the base. I then added some colours and textures from the material pallette. Total time maybe 7 minutes.

http://ixian.ca/pics7/sketchgear3.jpg

The final step is rendering. This took me quite a while because I used a new free plugin for SketchUp called Shader Light. I haven't actually used it before so it took some playing around to find a good looking setting(s). Including my learning curve for the renderer total time was about an hour.

Since anybody entering a black hole would be ripped apart into there molecules or even subatomic particles maybe the program is closer then you think.

Evan

Since anybody entering a black hole would be ripped apart into there molecules or even subatomic particles maybe the program is closer then you think.

Not necessarily. It is possible to have a very large area with a large accumulation of matter that exceeds the critical density to form a black hole. This type of black hole would be very different from the usual collapsed star that has then gobbled up everything that encounters it. A so called "low density" black hole would have no observable Swartzchild radius but it would still exist. You could pass through it with no clue that you had just entered a region from which you could never leave. The critical average density required for this to happen can be exceedingly low, much less than the density of air.

I wouldn't hold your breath on that Allan :p

Ageia's PhysX add-in card was a disaster. It was slower than running the game physics on the CPU host. Ageia did write a very nice PhysX API (game developer's library), which Nvidia bought and extensively enhanced. The physics calculations run on the GPU (the graphics card).

Many modern games run the PhysX API. Even hardcore ATI fans will buy an additional Nvidia graphics card to run the game physics :)

I use Google SketchUp 7 free version with a large number of plugins. Without the plugins SketchUp isn't good for much but there are hundreds of free plugins. The most important ones are the import/export file type plugins. One issue with SU7 is that they removed the ability to import DXF format. People screamed loudly so they issued a patch that you have to search for that enables the DXF import again.

There are a ton of tips and tricks to learn to make SU work for you. At first it seems pretty useless for accurate work but that isn't the case. The good part is that there are many excellent tutorials on line for free also. You really need to study the tutorials or you will be missing some of the very unobvious ways that make it much easier to use.

I dislike Alibre. I find it very clumsy to use.

Smokedaddy,

You mentioned a program you did this bracketry with as dim(s) ?? What is that? I am looking for a program that will do exactly what you have going on there, showing pics with dimensions and such. I do it all on graph paper now, which is so old school, but looking for the same thing on a computer. Also, that machine stand or column in the picture, do you make these? Are they available? I have an old Clausing mill head and motor, but no column or knee. This looks like something I could use to at least rig it up as a heavy duty drill press or something similar. I have a Bridgeport and two Southbends (10"/13") and tooling, etc. so I can make parts and the like. Was going to attemp to build a column and some sort of "knee" or adjustable (z-axis) platform using v-cut mounts/ways, then mount a univeral mill/drill table on it. Anyway, thanks for any info in regard...

Yes I would be very Interested about the software TOO!!!!

Thanks

You guys mean the software I used to model the stuff I posted above? If so, it's called Rhino. It's been arrond for a long time. Just about any CAD/CAM program I know does this kind of stuff.

... and Bigmo,

The pier is for and old telescope, called a Unitron. It is a replica pier as they are rarely found anymore. Yes I made the pier ...

When I did the retrofit from the Motor-Generator to Servo for my 10EE I did the adapter plate for the back gear box in solidworks.

Heres the render:

Heres the finished part out of cast with a couple goofs from learning Mach does not always start right when running from a point in the code:

Here is a free plugin to import DXF to SketchUp v8.

http://forums.sketchucation.com/viewtopic.php?f=323&p=274199

You will probably have to sign up to the forum to download it. The forum has a ton of excellent plugins available for free.

Another excellent resource is here.

They have hundreds of free plugins including many import and export filters for a variety of file types.

I have had the urge to do some art glass work so I did some fiddling with SketchUp and Pov-Ray. This is the sort of thing where POV-Ray kicks ass because it is a full powered ray tracing program and can model optical systems accurately. This is just a concept for a wine glass.

That wine glass reminds me of some glasses I bought once. They were square at the top also. It required a special technique to drink out of or you would be wearing the liquid. You had to drink from a corner. I threw them away.

Nothing wrong with free software. I will pointedly ask how many of the numerous online tutorials have you watched?

3D CAD has a steep learning curve mainly because the many little tricks that make it easy to use are not at all obvious. Tutorials are very valuable in getting you over the hump.

I sketched up some gears as an example. The total time to arrive at the finished model ready for rendering was less than 10 minutes. These images show the steps along the way in sequence:

I used a free involute gear plugin to make the gear. Time: ten seconds.

Then I pulled it into a three dimensional object with the push/pull tool and copied it in plan view to mesh them together.

http://ixian.ca/pics7/sketchgear1.jpg

I drew a circle centred in each one and pulled it to make a shaft.

Then drew a rectangle and pulled it for a mounting plate.

http://ixian.ca/pics7/sketchgear2.jpg

I stood it up with the rotate tool and drew a line across the bottom to separate a piece to pull out for the base. I then added some colours and textures from the material pallette. Total time maybe 7 minutes.

http://ixian.ca/pics7/sketchgear3.jpg

The final step is rendering. This took me quite a while because I used a new free plugin for SketchUp called Shader Light. I haven't actually used it before so it took some playing around to find a good looking setting(s). Including my learning curve for the renderer total time was about an hour.

Thanks for showing me this stuff, Evan.
I've been using it at work to make some 3D exploded drawings of some simple box structures, and pulley arangements, etc.
It's a good tool for showing peiople who can't concieve of a finished part from a 2D drawing. There are many of them where I work.

Here is another important couple of hints to using SketchUp.

When you make a small part or assembly such as the gear above then right click and make it a group. This will prevent it from accidentally interacting with other parts and being distorted or otherwise disturbed. If you need to work on it some more then right click and "Edit group". That prevents your editing from affecting any other parts.

There is another very important feature of the push/pull tool that isn't at all obvious. When you push or pull something you can move the cursor off the object as long as you are still pressing the left mouse button. What this means is that you can position the cursor on another surface somewhere that you want to match the height. As soon as you place the tool cursor on that surface the inference engine will automatically lock in the height of the part you are pulling to be precisely the same height. When you do this then any parts that interact with the part you just pulled will be automatically computed as Constructive Solid Geometry interactions unless they are grouped.

Also, when you push or pull when you let go of the part you can enter an offset in the input value window and the part will assume that offset. The value is always relative to the last position of the surface.

I am taking a class on Solidworks at my school. Unfortunately, it's just so blisteringly expensive, out of my reach. The finite element analysis program is really something - wish I had it when designing my camlock tailstock.

Any Sketchup users know how to get parts to look like polished brass?

I have drawn this many snows ago. Now, I only do have PDFs (in gray) that I converted.

The original can be seen here: incredibly small picture (http://www.swp-passau.de/pages/inhalt/ihre_stadtwerke/ihre_stadtwerke.htm) It is standing in Passau (Germany).

That Diesel Engine was built 1907 and it is said, that Mr. Diesel himself adjusted it.

Found the original pictures.
Just two of them:

Those masking strip tapes with the black dots on them were for photogrammetry. More than 1600 dots, something about 200 pictures from all perspectives imaginable.

I reconstructed the plans, MAN lost them during a fire.
