V15.1 PDS Internal Cutout - Close - Seam Allowance

EricFromBC

Hi all,

Is this something PDS cannot do, or me not doing it correctly?

A piece with an internal cutout...


When I close it, all the notches turned into the opening.


If I add the seam allowance, they go to the wrong side of the cutout.


Thanks in advance.

What value of seam allowance you are adding to internal?

EricFromBC

@Vasyl I selected the entire piece and defined all seams (positive) 1/4". On the outside perimeter, PDS correctly added the seams to the outside. For the closed H line, the seams are added to the wrong side.

Also tried selecting only the closed H line and add seam allowance to that. The seam is added to the wrong side regardless of positive or negative value.

I also tried splitting the line and rejoined to trick the notches to inside the cutout. Thought they would flip the other way when I close the H. They did not flip direction as in my original post. Adding seam to that also have the seam result.

So I did an experiment...

Draw a new simple closed H cutout. Adding seam to that work correctly.


With the seam on, adding more points to the line and moving them to the shape I want.


So far so good.


Still good.


Too early to celebrate...as soon as the line is bent, the seam allowance jumped to the wrong side.

I guess the shape is too challenging for PDS.

Hi. Try define internal corner as joint point.
Next label H,
Next seam allowance

can you send the piece so I can look at it, I'm not having an issue. though I have had it do this before.

@Vasyl
Thank you, moving the joint over solved the seam issue.

However, to start at that corner may have higher chance of heel cut.
