Add Placket Tool

What it Does

This tool automatically drafts a complete, production-ready tailored placket, including both the overlap and underlap components, matched precisely to your pattern’s slit opening. Whether drafting a classic tailored sleeve placket or a front neckline slash placket, this tool calculates all required fold lines, sewing baselines, peak geometry, and turn-under allowances from a single set of dimensional inputs

info

A new Placket Layer will be created within the active layer containing all the placket components.

How to Use

1. Activate the tool by clicking the Add Placket icon.
2. Select a place in the workspace to designate the top left of the placket.
3. Enter dimensional values (refer to the table below for descriptions).
4. Select Preview to see the completed placket.
5. Click Save to keep the placket or Cancel to abort.

Input Parameters

Parameter	Description	Drafting Considerations
Slit Length	The finished length of the slash cut on the garment body.	Determines the vertical depth of the finished opening along the sleeve wrist or center neckline slash.
Extension Length	The vertical height of the placket head extending above the apex of the slit.	Defines the finished decorative point, box, or peak that sits above the slash opening. Set to 0 for straight-across finishes.
Overlap Width	The finished visible width of the upper (outer/face) placket band.	Governs the visible front face of the placket where buttons, decorative topstitching, or edgestitching are positioned.
Underlap Width	The finished width of the narrow lower binding or concealed underlap band.	Typically drafted narrower than the overlap so the underlap remains tucked cleanly beneath the face band when closed.
Seam Allowance	The perimeter seam allowance applied to all attachment and turn-under edges.	Set to match your construction workflow.
