Hi Normand and thank you again for all the help.
For Tutorial, I was indeed thinking about trying to at least make a draft that you or someone else could review in order to ger something really useful. I also deal with a bit of a time problem, but I can start writting something and post it here for corrections, so that it reaches to something nice sometime soon. Now I don't know if that would be the best procedure, but if it is ok, I can start this week.
For chamfer/array, I'm looking and trying to reproduce what you did. Thanks again!
Last, with all the help, I got a bit more ambitious and I would like to get a spherical bottom for the part as seen here
Here is the file, but I'm almost shure it is not the most straight forward... at least not very elegant
... Oops, actually
the file is too big, here is just the starting part of it (I then used mirror and fusion to get the full object)
Do you have any suggestion to get this spherical bottom using another tool?
I'm building the rest of the object as the previous versions you suggested and post it when it's done, except if there is another way to get the spherical part achieved.
