How to make a frame with connectors?

Hallo.
There are many materials on the internet for creating welded frames. I would like to ask about tutorials for creating a frame consisting of profiles and connectors, for example used in the air handling units.
I prefer Inventor or SolidWorks.
Best regards

If you have SolidWorks, it has a built in tutorial on weldments. I have not made a weldment in years, but the tutorial got me started when I did have a bunch of weldments to make years ago.

These are the types of racks I later converted to weldments. Initially I had made them as assemblies, "Weldments" simply did not exist in the software when the frames were originally created.
