Sometimes it can also be used as a workaround - if some operation is having some difficulty handling a particular surface calculation shrinking it can sometimes change it enough to happen to avoid the particular problem.
That doesn't necessarily mean that it's always _better_ to do a shrink - it's just that it can possibly change things enough to make calculations behave slightly differently, sometimes maybe avoiding a problem sometimes maybe running into some other problem.
But if something is not behaving well, it can be worth a shot to try it to see if that particular thing then behaves better.
so basically, file size, could remove potential issues with some command and it can't be reversed. Hopefully, it can't cause problem of its own either.
With you a bolt becomes an true artwork, an admirable objet.
You have the precision of one watchmaker or clockmaker; same if I nearly missed to sleep during your tutorial; a little too technical & too long for a lively mind full of impatience.
What I don't understand, in the beginning of this tutorial, you tell us to make 20 copies of the 1 inch line.
After some more steps you delete all the copies and never use them. What is the meaning of those 20 copies? :-)
It was an easy way to determine thread pitch. By using this method you have an easy way to get the pitch right on and will use that to determine the other parts of the geometry. You don't have to spend your time figuring out or inputting to many values, you just need to know how many threads per inch / mm you want to model. Hope that makes sense, I'm not so good at explaining things.
By the way if you are using metric sizes the pitch is easy to determine since the second number should be the pitch. If this is the case you don't need to go through that first process, just use that number to start your pitch triangle.
