C-130J Plaque Modelling

One of my next projects is going to be a plaque with a C-130J on it. Here’s the picture I’m using as a starting point.

My hope is to be able to use the Model function to create a relief carving. Since this involves a lot of trial and error I’ve been using the new Version 8 Pro to make tweaking things a lot easier. So far, I have to say results have ranged from bad to worse. Attached is the V8 c2d
c-130J V8 Model.c2d (3.6 MB)
I’ve tried a number of tweaks, but at the Toolpath Preview, they all look pretty crappy.

My Plan “B” has essentially been to trace key lines from the picture. That has worked pretty well except for the propellers. No idea what shutter speed may have been used but some blades are quite clear and some are pretty fuzzy. And then there’s the blade pitch. It all makes tracing them a bit problematic. Maybe I’m just recognizing that I need to vary the blade width depending on the blade position. That’s really a totally separate issue. Will spend time redoing the blades. Below is Line drawing, which is definitely something that I can do. Use different bits (primarily 60° and 90° V-Bits) and varying depths ranging from .02" to .06" or thereabouts. The various colors are simply to make drawing / tracing easier for me.

By far, my first choice is the relief carving, so your thoughts are very welcome, even those saying “forget it!”

Search for “c 130j 3d model”. Some may require money, and some are free with licence conditions.

You can then create a Bas Relief from a download (stl or obj are typical) using software tools, of which there appear to be some paid tools online, vcarvePro, or 3D modelling tools that will require extra work. Search this forum for “bas relief.”

Pick the best looking prop & trace & copy it. As for the 3D model, I’m with Andy. Find a good 3D model, orient it the way you want, then import it at your specific height.

Note that we do sell a tool specifically for converting a 3D model into a bas relief:

This is 3D model reoriented to a similar view as above, and scaled down to 3/4" height.
Cut into a 1" thick stock. The model didn’t have props or lettering. They would have to be added.

I just gave a quick try in Fusion to convert the image to STL.
I does not look very good.

There are a number of C130 3D models out on the web. I am not sure of the quality.

Here is the image file I modified to try an make a STL file. Removed the background and increased the Exposure.

The STL is too big to post even zipped. I can send you the Zip in an email. (8 MB )

Sounds good . nancy.and.bob@columbus.rr.com

Got it. Unzipped. 163MB.

This is my first time playing with STL

In CC Pro,

  1. Created New File for 14 x 14 x 1 board
  2. Created box 12.5 x 9.5
  3. In Model created a flat thing that I labelled Boundary .3" thick
  4. clicked on the ball shaped icon and selected c130j2.stl

Nothing happened. Watched for action using Task Manager. Saw almost no action. What am I missing?

i do not have CC Pro, so I can not help there. Do you see a preview of the model ?
The image is 640 x 500 pixels. I used 1 mm for each pixel and 8 mm for the overall height.
The STL is saved in inches ( the problem ? ) and is 25.315 x 19.645 x 0.390 (z)

@SDGuy has a link for a model that would probably allow more manipulation options.

Is the STL saved in binary? (Can you read it with a text editor?)

It’s in ASCII format. I knew that was an issue, not sure about inch versus mm.
Currently inch.

Here is a link to the file.

Is this what it is supposed to look like?

Note that if you have Microsoft Windows you can open it in their 3D Builder app and re-save as a binary STL.

Got this message when I clicked:
Spooked. Got this when I clicked on Lockheed etc

Which link ? The Google drive is the same file I emailed to you.
Not sure about your spam message.

What are the rules on acceptable STL file for CC Pro ?
Are both ASCII and Binary acceptable ?
Are inch and MM acceptable ?

I know I have seen this in threads before somewhere.

The original image is small (644x500) pixels.
It would probably look better if scaled down enough, but that my be too small.
A larger image would be better.

What is the intended plaque size ?

Has anyone opened the STL successfully in CC Pro ?

STL file Lockheed Martin C-130J Super Hercules 🛩️ ・3D printable model to download・Cults is where it took me when I clicked on Lockheed Martin C-130J Super Hercules

I’m anticipating making the plane around 10" wide

When you opened the file in 3D Builder, did you simply ignore the error message in the corner? Will - I accepted the Repair option and it’s been running for 20 minutes. Using 14% - 15% of 4800K CPU and around 5 GB of 16 GB memory. Seems pointless. About to kill it.
