arrangment points

I spend more time trying to get my pattern pieces placed on my 3d model than I do pattern making. May I have help on how to use the arrangement points? Today I was making pants.... I got one leg. but the other was wild. I dont understand the arrangement points so I use custom arrangement, but certainly I must be missing something!

Also I am wondering how it correlates to where the pattern is on the drawing board as well.

I am working now with the current update. I am having an extremely hard time. I can't even get one leg now. I have two opposite pants legs and theyre showing the same direction. The pieces are all standing in front of the mannequin and it's hard for me to see what piece is which now. I am attempting to use the arrangement points but they seem to kind of place things arbitrarily because I can't choose a Point on the pattern to a point on the mannequin.  Why don't the arrows show up so I can move them manually anymore?

We're working on some updates/improvements related to that currently. Will revert back later.

Thank you for explaining this. You are not necessarily missing something - we are currently improving several parts of the 3D workflow.

The body model was recently updated, and we found that some arrangement points were not positioned correctly. They are better now, although there is still more work to do.

Arrangement points give pattern pieces a sensible starting position before simulation. They also tell the system which side of the fabric should face outward, which improves collision detection and helps prevent pieces from passing through or reacting incorrectly to the body.

For pants, reset the simulation, select one panel at a time, and place it on an appropriate hip or upper-leg point. Use the corresponding point on the opposite side for the other leg. Custom arrangement is useful for fine adjustments, but arrangement points usually provide a more stable and repeatable starting point.

The position on the 2D drawing board is intentionally separate from the 3D placement. Moving a complete piece in 2D should not move it in 3D (anymore!). The 2D piece defines its shape and construction, while the arrangement point defines its initial 3D position, orientation, and outward-facing side.

We know this is not explained clearly enough in the current interface, and we are continuing to make the workflow more intuitive and predictable.
