But just after create it, and before to start, I’ve had the habit to saved it, so I click on the « Save » button, but the name I’ve put is replaced by « pattern.val » in the box for saving.
This name refers to the pattern drawing board and not to the actual pattern file.
I prefer to only use one drawing board (draft block) for all my pattern pieces. This way, I have everything available to me at all times while I’m drafting or designing.
When I have created a new pattern file and I save for the 1st time, I give the name of that pattern in the save tool.
It is a bit confusing but, as you can see, I only use one board to avoid all confusion
You can create different ‘Boards’ to design different parts of the pattern on and you can name these ‘Boards’ as you wish. I like to think of them as different pieces of paper. So if you wish to use them and name them differently, then you may. But on different pieces of paper, you can’t draw lines from one to the other accurately. Likewise, when you use formulas, you can’t access the length or angle of line on the 2nd board while working on the 1st board. Nor can you draw a line from a point on the 1st board to a point on the 2nd board.
I don’t think the explanation is misleading in the manual. But it’s very different from saving your pattern. And yes, saving the pattern does save the whole container containing all the draft pieces.
