I came to this thread hoping to find an answer to a similar problem. I cut/pasted a portion of a large model into a new drawing in order to manipulate it in a smaller file size. When I did this, a number of the lines auto-softened.

Running the aforementioned slider all the way to 0 did not solve the problem. Grouping everything and then exploding it, did.

Thank you very much! I'm sure they will come in handy.

Having just started with SU a couple days ago, the most important tip I've received is how to multiply/divide a copy.

For example, I wanted to make a brick wall. To use this feature:

select the object to array
select the "move" tool
push ctrl (this shortcuts the copy feature)
click on a part of the object as a base-point to move from

IF you want to use the multiplication tool

place the copy in the direction you want your array of copies
also place the copy a distance away from the original at desired interval (all copies will have this spacing)
after placing the copy (before leaving the move tool) type in the number of copies you want in the format "#x" for example, if I wanted 3 copies made in addition to the original, I would type "3x"
if you need more or less, type again. you can edit the number of copies until you leave the tool

ELSEIF you want to use the division tool

place the copy in the direction you want your array of copies
also place the copy at the desired position for the last piece
after placing the copy (before leaving the move tool) type in the number of copies you want in the format "#/" for example, if I wanted 3 copies made in addition to the original, I would type "3/"
instead of continuing outward infinitely like the multiplication tool, the division tool will space the copies out evenly in between the original and the specified end piece.
if you need more or less, type again. you can edit the number of copies until you leave the tool
