I was working on a project recently and wanted to generate a rendering that looked more like a concept drawing, than a realistic rendering.
The model I used for a test is here: https://grabcad.com/library/pacifier-2
I found the image below online as a reference for what I am looking to try and recreate. Is Photoshop or Illustrator normally used for these types of colored sketches?:

Below is what I came up with using Keyshot:
I think the goal is termed "non-photo realistic rendering". I find people sometimes focus on the appearance too much when a photo realistic rendering is presented. Instead I want them to focus more on the shape, and in this case the color scheme.
I know Keyshot does Toon Shading, but toon shading is a little too sparse. I would like to make the shadows in the image more like the Shaded Toon shadows though.
Let me know if you've done similar things, or give it a try and post some results here.
I have the same thing in my mind
Well...
I don't know how professional designers present there concept sketches. I don't have any experience with this regard.
But how Im planning to do these type of presentation is.
I'll first model the part(porduct) in cad software and then create some different angles of views
Open the drawing sheet
Insert those views randomly and then import those jpeg into photoshop or illustrator
Add colours n blur effects n sketch effects etc
Let me know if this works.
Have fun playing.
Hi, not as good as the one you are referencing, Steps were
I think it would take a lot of time (2-3) hours to really develop the drawing, but these steps work.

I like those sketch lines. I'm not sure I can incorporate them in my curved object, but for squarish stuff they look great.
I saw that a non-photorealistic rendering option was/is available for Rhino. It is called Penguin. It does not look like it has been updated in a while, but it gives some interesting results.
I'm going to keep adjusting Keyshot and trying different materials and layers, then stacking said layers in Photoshop. I'll post back some results if I get something attractive, that doesn't take too long to produce.
I'll likely forget how I did this by tomorrow, but here is a version with some of those fancy sketch lines:
First of all i dont know that there is a thing called TOON in material in keyshot
Thanks mate..I tried it
And the result is amazing
I always been wondering how on earth ppl are doing like that..
Now I know
Thanks again
I'll upload the file in a while
