Techpacker vs Illustrator for tech packs

Adobe describes Illustrator as vector graphics software. For apparel work, vector paths let you draw front and back flats, seam lines and detail callouts. A flat shows construction intent; it does not establish the actual fit measurements.

Techpacker documents reusable cards for sketches, materials and measurements, collaboration and tech pack exports. Its value is organizing those inputs. You still need someone to supply and approve the garment data.

Suppose you change a hoodie pocket opening after sample review. In a manual workflow, update the flat, the pocket measurement, the construction note and the dated revision record. Export them as one matching release rather than emailing only the new drawing.

In a collaborative tool, update the relevant sketch and measurement records, then check the supplier view and exported pack. Record who approved the change. A live file should not make it ambiguous which revision is authorized for bulk.

Build one representative style with front and back flats, a BOM and a measurement table. Export it and ask your manufacturer whether dimensions, units, callouts and revision labels are readable.

Check whether teammates can edit only the records they need, whether supplier access requires an account, and whether an approved pack can be saved as a stable snapshot. Verify these details in the plan you intend to use.

If one person develops a few styles and maintains disciplined revisions, changing tools may add unnecessary setup. A shared system becomes more useful when several people repeatedly reuse materials or revise the same styles.

Neither choice removes the need to review fabric, fit and construction in a physical sample. Send the pack with all unresolved decisions clearly marked.
