Thank you so much. Your help was far more than I expected and finally clears up for me how to have multiple solids in a part file. This is very helpful, do you offer any paid online courses in addition to the videos on Youtube (more of a course than individual topics).
I digress a little but I found a basic course at "cadtrainingonline.com" that offers basic course and apparently includes 3 years use of Inventor (not LT) which would support assemblies, cable looms and sheetmetal. Do you know anything about this? I'm not sure what the "gotcha" might be here because the course with included software is less than $600 USD but a subscription to the non LT version of inventor is nearly $3000 per year. There must be something I am missing here?
