A friend on the Forum asked me to 3D print the end landing of a Passenger Drumhead car.  The friend showed me photos of the damaged end that was as broken as the forum-ite was. The broken part was sent to me.

I felt the pain!


So this emerged. I did change a few elements such as the vertical supports that are fully made and not flattened.



And it printed like this.

pass 1b

pass 1

pass 2

a little more snipping of print spues and black paint.

I am marveling at the stuff you can turn out on your 3D printer and the GlowForge.  Your packaging looks better than a lot of my work!

How did you work out the detail of that platform, was that all hand drawn?  How long did it take to get that model ready to print?

Clearly, in skilled hands, 3D printing can change a lot in our hobby, previously unobtainable parts are suddenly available.

Two programs   Coreldraw and Rhino. Skills in both are an outgrow of mechanical drafting that goes back to high school.

There  are many YouTube videos on both programs for beginners and advanced.

So instead of a drafting table I use a computer.

Take measurements with a digital caliper and like a draftsman copy those in the program in 2D. Then I UNlike a draftsman extrude the 2D drawing into 3D based on measurements.

Then electronically drill holes and cutaway other parts as the measurements require.

Doing thus I'm not limited to any Plastruct shapes that can fix a model's dimensions.

That answer my question!  Sadly, I don't have any 3D CAD experience from anywhere.

When I was working in Aerospace, many of our instruments had very intricate gear trains to drive multiple pointers.  I marveled at how the mechanical guys would get all that stuff working.  It made my electronic design and programming tasks look pretty mundane.

Does CorelDraw import or read SVG vector files yet?

And in other news, I'll be looking to get replacements for some broken 1970's era O scale AHM boxcar ladders (I acquired a small quantity of these cars and upon finding out how few different ones were made -- 3 or 4 each of boxcar, reefer, flatcar and gondola-- built a collection representing their entire lineup).

Should be simple to soon as I get one off my small collection and put the calipers to them. I could draw 2d diagrams in Inkscape (.svg) or 3D ones using SketchUp Make (.skp)
