If you wonder about a specific vertice, go into point edit mode of your joined object and lasso a single vertice in the view with shift pressed... down in the lower left it will tell you how many vertices actually got selectd...

I also must say I don't quite get your way of working?
Is it just for the test you use a plane and gut it with a cylinder to get the final form?

Just wondering for I see no real advantage of doing it that way for that form...

I don't know your inner diameters for the rings... but I am going to make a try...

The object is added as a zip below the picture :)

It was a test but also I did not immediately know of a better way of doing it. If the Tube primitive had a selectable wall thickness, that might be one useful tool also.

Sometimes one would need to carve pits to a block that don't go through the block entirely. In a metal shop there is a special drill tool for that with flat tip. I was trying to find a way to do something similar but the Slice command tells of a proximity error when I tried it. So only holes that go all the way through the block were possible.

Thanks a lot for the many pieces of information, I will look into it next.

Your example object is water tight and here is how it looks in Slic3r printer software after scaling to 10% and flipped on Z axis: https://s13.postimg.org/gy5ujqtzb/Example_Object1slicer.jpg

It looks like it is ready to print. The printer software tells your object has 1 shell whereas mine had 2.

I used the Export STL button in the Slic3r software and when that copy is opened in the printer software it now has the correct dimensions but scale is 100%. So that file would be best sent to the printer service provider for printing. Most likely a desired object would be received in the mail.

At least that is what I am going to try next, there are plenty of 3D printing service providers available on eBay.

I will also have to check licensing of the AccuTrans and Slic3r software because it is practically time to produce some physical objects ;)

May I still ask how did you produce the ring part? I did not see an easy way to do it, that is why I used the Plane primitive sliced with Tube primitive (and needing work on the dimensions)?

Ok,
create a disk, 150 diameter
select the inner edges, the "spokes"
Fracture
select the inner circle points
scale to size
select the innermost edges again, the center spokes.
fracture
scale to size
The two now represents the risen band later
select the innermost edges again
fracture
scale to the size of the hole in the center
remove the center vertice

you should now have something similiar to picture 264

select the whole object
extrude 20 units
select the faces of the band to be raised
extrude 20 units

the object should now look like picture 275

Cleanup extra unneeded faces if you want.

Most excellent. It is like sculpting or lathing in Forms editor but from the top view whereas the same would happen in cross sectional in Forms.

I will try to digest it and send a simple object to a 3D printing house, let's see what could come of it.

Thanks again for all the info.

Sure thing...

Usually use either Blender (which I am trying to learn) or
Sketchup nowadays.

Sketchup used to be really good at this form of editing...

Blender is quite good to extrude with and also works fine for booleans.
