When you need to create complex geometry in SketchUp, it is often better to break an item into positive (solid) parts and negative (void) parts that you can then subtract from each other with SketchUp's Pro's Solid Tools. In this example, I am showing this process for a cast steel structural connector, but the principle applies to many other shapes as well.
Because this process uses solid geometry from beginning to end, the result is also a solid and therefore easily 3D printable.

Some of the tools I used here are:
SketchUp's built-in tools:
Solid Tools (specifically the Subtract tool)
Parallel-projection camera view

In this video I am having a bit of fun with the new SketchUp Diffusion tool…
Give this a try: Add only a single cube to your modeling space and then try to create an interesting visualization from that using only the prompts and the styles in SketchUp Diffusion. This is actually a great way to explore prompt engineering. It is interesting how the AI is able to capture the general orientation of the scene from just the cube and the horizon line behind it.
You can find my original forum post about this on the SketchUp forums here. And admittedly I based this on a competition that the Blender community has been doing for a while. Check those out, too.
For more on what you can do with SketchUp and Diffusion, take a look at my initial post about this topic.

In this (beginner!) video tutorial I give a very basic overview of the process needed to create a SketchUp extension from scratch and then distributing it as an RBZ file. Admittedly, this isn't completely from scratch since I am starting with a template file that you can simply download from this site, but the result is a very basic yet fully-functional SketchUp extension.

In this video tutorial I give a first glance overview of the new SketchUp Diffusion tool. Throughout, I am combining a basic how-to tutorial for SketchUp Diffusion with my various thoughts on the tool (given several different use case scenarios) and the general usability of AI for visualization and ideation.
While it is indeed still early days for this technology, it is already quite impressive what it can do. Good looking first renderings can be done quickly, even from minimal geometry. However, there are some caveats and I am very curious how the next iterations of this and similar tools will impact the AEC industry.

To my readers, viewers, friends and colleagues:
I wish you and your loved ones a peaceful and joyous holiday season, Merry Christmas (to those that celebrate it), and a healthy, happy, and successful New Year 2024! And just to reiterate what I said in last year's post: A little bit more peace on earth would also go a long way!
As usual, I made this video "card" completely in SketchUp. Want to see how I did this? I’ll post a tutorial soon to sketchupfordesign.com and my YouTube channel.
Cheers,Alex
