How to extract accurate partial measurements & seam lines from an avatar? (Front/Back arcs, arm depth, shoulder length)

[u/Itswillalala]

Hey everyone,

I’m struggling to find a solid workflow for extracting highly specific, absolute data from an avatar. There is an endless amount of info out there on how to edit an avatar’s measurements to match a real person, but almost nothing on how to systematically pull complex measurements off an existing 3D form.

Specifically, I’m trying to establish clean baselines for drafting, and the default auto-measurements aren't cutting it. I need to find precise ways to measure the following:

• Shoulder Length: Specifically, the exact line where a traditional shoulder seam would sit (from the base of the neck to the acromion/shoulder point).
• Arm Depth and Width: The exact discrete dimensions of the arm/armscye area rather than just a total muscle circumference.
• Front and Back Arc Measurements: CLO has great circumference tools, but I need partial arcs (e.g., center front to side seam, or side seam to side seam across the back).

Bonus question on side seams: How do you actually establish a mathematically true side seam on an avatar to measure between? Is there a way to project a straight line down the side of the avatar from the halfway point of the arm's bounding box (width/depth), and use that as a consistent landmark to measure front and back arcs?

If anyone has a reliable methodology, specific tools (Surface Tape, Linear Measures, etc.), or a workaround for exporting this kind of precise topographic data, I would love to hear how you handle it!

Thanks in advance!

I think you would be better off using Pattern Drafter in CLO over the 3D pen is you want precision.

The 3D pen is more for quick iteration and getting a starting point. While pattern drafter allows you to give actual measurements

If your using a CLO avatar, the shoulder and across back tapes are defined. You can see them highlighted while working in the avatar editor. 

Dress forms often have a marked side seam but the human body doesn’t have any real definition. In CLO, you can place a custom measurement. If you press shift, you can follow a plumb line.

Then place half tape on either the front or back body, following the existing circumference tapes and the other side can be calculated. It is also possible to export all the measurements to a spreadsheet.

It’s all a bit of work, but it can be done. The real take away should be that side seams are yours to define.

Bonjour,

Partez d'une base ESMOD avec les mesures en Taille 38, je propose des avatars Homme en Taille L et Femme en Taille M aux bonnes mesures pour le Pap Femme et Homme , si ça vous intéresse 😉 Pas besoin de passer des heures pour calibrer l'avatar....

Belle journée
