Cannot find "Hem" tool

[splainer]

I'm running version 0.6.1.1. I see from the change log that a Hem tool was introduced into the Detail mode earlier. I cannot find anything referring to Hem in the user interface.

There is no separate hem tool. You can create hem as part of piece if you will include custom seam allowance path as main path.

[splainer]

Just to make sure I understand, is this what you recommend?

1. add a separate path in the drawing mode that is <my hem allowance> distance from the finished edge
2. select that separate path rather than the finished edge path when creating the workpiece
3. back in drawing mode, add the path for the finished edge as an internal path

No.

Yes.

But then you create a piece with "normal" path. To add hem you will use tool Piece Path and select type Custom seam allowance. Then in piece options you will include it between two points of main path as main path. You must understand that this way you extend seam allowance. So you will have nice looking main path and seam allowance.

Sorry to be thick, but I truly don't get it. I've attached a sample that I'm struggling with. The Details view shows the main piece with .25" seam allowance throughout. The top, curved waistline (the curve SplPath_CBExt_CF) should be hemmed at .5". Similarly, the curved legline (SplPath_L2_L_1) should be hemmed .5 ". In the Draw view, I have created curves (colored in magenta) that approximately replicate the waistline and leg line, .5 inches away from those finished edges.

I do see now how to get custom paths of type seam allowance to appear in the Seam Allowance tool, but I don't see how to make the connection to the main piece in a nice looking way.

I appreciate your patience with me here. I would be happy to contribute to the wiki on this subject once I understand these nuances.

Just wait, i'll make for you video. Also i have found several bugs in code. I need to fix them first.

[splainer]

Thank you for this tool and for the amazing response time.

[Roman Telezhynskyi]

What you have been trying to achieve can be done just with Before and After seam allowance values. But this will work only for such simple cases. Because your seam allowance repeats your main path.

This is how it must be included

[splainer]

Before and After seam allowance indeed work fine for the L2-L curve. Thank you.

The CBExt-CF curve eludes me, though. If I understand how "Before and After" are meant to work, I would think that I'm meant to change the After of CBExt and the Before of CF to CurrentSeamAllowance*3. The picture shows an odd result. on each side:

1. (CBExt with strange angle
2. CF-C1 now tapering from the adjusted value to the default value.

This solution almost works for the waist, except the detail shows an extra line coming up from the left side of the waist. I can obviously use this, but wonder what I'm doing incorrectly to get that extra line.

I made this by extending my custom path above the waist left and right by the regular seam allowance amount and using it as custom seam allowance between CBExt and CF.

Looks like a bug for me. I will investigate.

Nice trick. I like, except, to work you must make "seam allowance" little bit bigger. For example 0.26 works for me. I am talking about point SA1.

Very interesting case. Just tip for you. Look on your curves. While you are thinking and experimenting i will think how to improve Valentina.

[splainer]

Great tip. I am guessing that you intended me to remember to blend my curves at the intersections. Once I did that, the Before and After seam allowance adjustments work great.

I have fixed this case in #915.

@splainer can we close this issue?

[splainer]

Yes.

[splainer]

Functionality for basic hems exists in seam allowance tool.
