Posted the question on another forum and they gave me the suggestion of an industrial grader.

I couldn't sleep last night so came up with this. Its a close approximation of an old style grader.

For fun, this is a render of the model/pattern I get from the above image.

Sorry, don't understand the question and/or comment.

Occasionally I share patterns that I make from 3d modeling practice, doodling or experimentation. Also occasionally, I ask the community what type of pattern they would like for me to share. In this case, the only suggestion, so far, was for a grader.

The grey scale height map image can be thrown into different cnc software packages like Aspire or miscellaneous 3d software (free to expensive) and converted to an STL for cnc routing or laser engraving.

Hi,

Thank you for the kind words. I modeled it using Blender 3d.

With a few exceptions, I don't normally share the obj or stl. In addition, I did particularly bad modeling using several modifiers and made up a bunch of stuff since I am not familiar with industrial graders. It would take additional work to get a decent obj or stl. I modeled this in an insomnia induced haze in the middle of the night.

But are you saying you wanted to see the model with an engine modeled instead of the square block I have in there. lol

If so, post a picture or link of a motor you would like for it to have.

Quick note for new 3d modelers interested in making their own cnc patterns/3d models
.
The above statement about the 3d model making a bad STL or OBJ probably needs a tiny bit of clarification.

There are different ways to create and move geometry. And different programs do it differently.

CAD software uses a parametric method that is really efficient but you have to define all aspects of the geometry. It typically does not allow you to do bad things.

Artistic 3d modeling software uses polygonal modeling and gives you more freedom of creativity but because you are not defining all aspects it does what it does. Meaning you can have horribly overlapping surfaces, holes, wrong facing faces, double vertices, wrong facing vertices, ....etc.

Neither is inherently good or bad. There are use cases where one is more efficient than the other.

I personally prefer polygonal modeling with Blender and Zbrush but I am familiar with Fusion 360 and hate modeling with it. It feels like I have one hand tied behind my back and blindfolded but it is really hard to make bad geometry. I love working in Blender but occassionally I make unusable models.

Staying with the sports motif I was asked to make a pattern with a soccer theme (input from other site).

Fairly happy with this version. Did a few previous ones and wasn't as happy. The ball without texture looks like a volleyball so worked on it to make the shapes stand out.

I've never played soccer so don't know if there is a more universal representative image for it. If there is please let me know. Soccer was not a thing in West Texas in the 60's and 70's when I was a wee lad.

I guess I just missed this post. Looks like you made a few more good models. I'll have to check them out.
