Hey all,
When looking throughout the forum on how to true patterns I only found Dart Truing. Is there a way to true things like Armhole Connections, Shoulder Connections, Crotch Points, etc?
I don’t know if my question makes sense so here are some pictures to help.
This is an Armhole peak before truing and the dotted line is where it needs to be cut off to get a trued armhole curve.
This is a crotch point being trued where the green side is the trouser back and the orange side is the front. The line drawn by the red marker is the where the pattern must be cut to get a trued curve.
To manually do this, you just need to align the sides of the tip and draw/cut off the peak, but is there a way to do this in Seamly 2D without manual intervention?
One idea I had was to make each of those peaks a 90-degree angle, so that when the sides are aligned the 90 on one side and the 90 on the other would make a 180-degree straight line that is sure to not create a peak.
Here you can see that I used the Move tool to move and rotate the back yoke of a shirt onto the front, lining up the shoulder seams:
This way, I can make sure that the neck curve moves smoothly from the front to the back, land I can check that the front and back armholes transition nicely. If they don’t transition nicely, then I can tweak the curve handles (using formulas) until they do.
This one is a bit more complicated because the trouser front & back are drafted on top of each other:
I had to do this in 2 parts… first I mirrored the back and then I moved it to match the inseams.
Step 1 - Mirror
Step 2 - Move
So here you can see that the inseams are matched and the front & back curves flow smoothly into each other.
And here, I’ve done the same at the side seam to check the waist curve.
I normally do the seam curves first. This way, I can use the curve handle directions of seams to direct the connecting curve handles at 90° (as you mentioned in the 2nd comment), but you still need to check that they don’t form peaks & valleys after they’re connected.
I’m having trouble rotating the pattern to get to where I want it to be. I don’t know how to get the point positioned right. Is it possible that you are free to have a quick Zoom when it is evening time for you?
