Every physical sample costs a production team capacity, material and calendar time. Teams using 3D garment design software build fit and review a garment digitally from 2D patterns (export production files tech packs) so they can review fit before anyone cuts a physical sample.
For manufacturers and vendors the value is capacity. Every fit issue you find on screen is one less sample to cut, ship and review. This guide explains how it works (how your team runs it), what they need to run it (what they have), what it produces (what you get), where physical checks still matter (and how to start without disrupting production).
The software turns a flat pattern into a virtual garment. The team loads 2D pattern pieces, stitches them on the digital body, sets fabric properties and watches the garment drape and hang like a real one would. Digital sample: a virtual prototype that factory, brand and retailer can review without shipping anything.
Three words here: virtual prototyping - build and review the garment on screen before anyone cuts fabric; fit testing in 3D - check the garment on a digital body size by size and adjust pattern; digital product development - digital sample, measurements and review history travel together from design to production.
That linkage is what separates production software from tools that only make a good-looking image. A picture helps the client approve a look. Digital sample tied to real pattern and real fabric data helps factory decide how to build garment.
Hardware. Browzwear has separate Windows and macOS requirements on its system requirements page. Check the Windows list against your VStitcher version before you buy machines. The Macs figures follow.
| Item | macOS minimum | macOS recommended |
|---|---|---|
| Operating system | macOS 15.4 Sequoia or later | macOS 26.1 Tahoe |
| Memory | 16GB | 32GB |
| Display | 1920x1080 | 2560x1440 |
Browzwear also recommends Apple Silicon M1 or newer. Ray tracing (rendering method that produces realistic images) is not available on macOS. Browzwear does not recommend running VStitcher or Lotta on virtual machines so install it on a physical laptop/workstation.
Versions. VStitcher 2026.3.0 has release notes from October 30, 2026. Support is for VStitcher and Lotta versions 2026.3, 2026.2, 2026.1 and 2025.3. Version 2026.3 reads files from earlier versions but earlier versions cannot open 2026.3 files. Clients may sit on different versions so agree which version you are using with each client before you exchange files.
| Output | What it gives production |
|---|---|
| Digital sample | A shared 3D reference that the factory, the brand, and the retailer review before a physical sample is cut |
| Points of Measure table | Size-by-size measurement values that export to CSV |
| Fabric data in a U3M file | Measured bend, drape, thickness, and stretch and recovery |
| Production files such as tech packs | The approved garment's specifications for the factory floor |
| Review history in Stylezone | A full record of design updates and comments in one place |
Each output removes a handoff where information used to get lost.

Physical sampling doesn’t go away when a team adopts 3D. Most fit, construction and measurement decisions are pushed onto the screen so physical samples that remain answer harder questions. A digital sample is only as accurate as its data. Plan a physical check in these cases:
Enterprise buyers can refer to Browzwear’s guide to the eight enterprise criteria for the full evaluation frame. For a manufacturer, four questions weigh most heavily.
The investment concern is valid. Retraining a team and connecting systems takes effort. The practical answer is pilot one style family not factory-wide rollout. A pilot costs less, exposes integration questions early and gives you your own numbers.
Browzwear doesn’t publish a fixed learning time so measure it in your pilot. Pattern makers and technical designers already know garment construction but 3D adds body, fabric properties and simulation on top. Browzwear University provides on-demand VStitcher courses broken into lessons, quizzes and activities with certification and progress analytics for employers. The courses are self-paced and fully virtual so your team can train between production deadlines.
Yes. VStitcher and Lotta are macOS 15.4 Sequoia or later and at least 16GB of memory supported. Ray tracing is not available on macOS.
Browzwear doesn’t publish any fixed duration. Browzwear University has self paced courses with certification. Take a pilot with your own technical designers and pattern makers.
It moves most fit, construction and measurement review onto the screen - not every physical check. Unmeasured fabrics, finish changes and client sign-off rules can still require a physical sample.
Browzwear lists its plans on the pricing plans page. Look there for plan that fits your team size and workload.
Browzwear doesn’t recommend it. Install VStitcher or Lotta on a physical laptop or workstation.
No. Version 2026.3 reads older files but earlier versions cannot open 2026.3 files.
