Pattern

Part I: Pattern Import

Purpose:

Import pattern pieces into the 2D window.

Operation Path:

File ➡️ Import ➡️ Import DXF File

Operation Instructions:

You may also import DXF files by dragging‑and‑dropping them into the 2D window.

Import Options	Operating Instructions
Load Type	Open: Open the file and overwrite the original project.
Load Type	Add: Import files without overwriting the original project.
Rotate	Rotate the content of imported DXF files after opening.
DXF Format	Read the DXF document according to its format type. When opening a DXF file, ensure the selected reading format matches the format used when the DXF was saved.
Scale	Millimeter / Centimeter / Meter / Foot / Inch (Adjustable by percentage).
Scale	Auto‑Scale: When checked, the system detects units automatically and adjusts scale accordingly.
Grading Rule	Read files based on corresponding grading rules from DXF or RUL files.
Encoding	If imported text appears garbled, try changing the encoding method. For users unsure of system encoding, manually try UTF‑8 and GBK. Traditional‑Chinese Gerber users with character‑display issues may resolve the problem by selecting BIG5 encoding.
Import Seam Allowance	Enable this option to import seam allowance together with DXF content.
Import Pattern Annotation	Enable this option to import pattern annotations from the DXF during import.
Auto‑add Curve Points Grading	Enable this option to automatically apply grading to curve points on imported pattern pieces.
Optimize All Curve Points	Enable this option to reorganize edge curve points and reduce total point count.
Auto Distribute	Enable this option for automatic pattern‑piece distribution. Rearrange: Pattern pieces will be redistributed. Avoid Overlap: Auto‑distributed pattern pieces will not overlap.
Reverse Grain Line	Enable this option to reverse the grain‑line direction of imported patterns.
Auto Trace as Internal Lines	Enable this option to auto‑trace base lines as internal lines.
Copy Cutting Notch to Sewing Line	Enable this option to copy seam‑allowance notches onto the pattern sewing line. This is especially useful when notches exist only on seam allowance but not on the sewing line.
Reducing Turn Points (Smoothing Points)	Enable this option to reduce turn‑point quantity. This helps handle older CAD‑generated DXF files that export only corner points and omit some curve points, such as files exported from Lectra.
Fix Sewline	Enable this option to align extra CAD‑generated seam‑allowance data with actual sewing‑line positions.
Distinguish Fabric by Material	Enable this option to create new fabrics according to fabric names contained within the imported DXF.
Reset	Reset all above settings back to factory defaults.

Part II: Pattern Editing

I. Home Tab

Select / Move

Purpose:

Select pattern pieces and perform operations on them.

Operation Path:

Home ➡️ Select / Move

Operation Instructions:

Selection: Click to select a pattern piece. Hold Shift and click or drag‑select to select multiple pattern pieces.
Move: After selecting the pattern piece, hold down the left‑mouse button and drag to move it.

Right‑Click Menu for Selected Pattern Pieces

Operation Path:

Home ➡️ Select / Move ➡️ Select internal shapes ➡️ Right‑click Menu

Tool	Purpose
Instance Pattern	Generate another pattern piece mirrored from the current one. The two pieces maintain a linked relationship. Linked relationship means any modification on one side will trigger corresponding changes on the other side.
Create Lining	Generate a copy of the current pattern piece to be used as lining or outer fabric.
Create Internal Shape by Outline	Clone pattern piece into an internal‑shape graphic.
Create Internal Shape by Outline and Sew	Select the pattern piece, right‑click and choose 'Create Internal Shape by Outline' , then click the target position for the new internal shape.
Clone as Reference Line	Generate reference lines based on current sewing lines and internal lines for pattern‑editing reference.
Deactivate	Deactivated pattern pieces skip simulation and collision calculation; they remain unchanged even if visible in the 3D window.
Freeze	Frozen pattern pieces will not deform when colliding with other pieces.
Strengthen	Harden pattern pieces during simulation to quickly obtain flat results; suitable for simulating stiff fabrics.
Solidify	Solidify the pattern piece to its current shape. It will no longer undergo major shape changes after simulation‑collision.
Offset Pattern Outline	Expand or reduce pattern seam allowance by an offset distance.
Add Internal Isoline	Generate internal lines parallel to the outer outline of current pattern piece.
Add Random Vertical Internal Lines	Generate a set of approximately‑vertical internal lines on the selected line.
Select Patterns with Same Specified Properties	Quickly select other pattern pieces that share identical specified properties.
Create New Fabric	Rapidly assign new fabric to selected pattern
Replace Pattern from DXF	Update and replace selected pattern pieces after editing in external CAD software. Sewing relationships are preserved to avoid re‑editing seams and improve revision efficiency.
Apply new pattern	Revise and replace selected pattern pieces. Positions and sewing connections remain intact, no reseaming required for higher revision efficiency.
Attach To	Attach selected pattern piece onto another pattern piece.
Group	Group multiple pattern pieces together for organized management.
Align	Align selected pattern pieces for tidy 2D‑view layout.
Order	Adjust the display order of pattern pieces in the 2D window.
Lock	Lock specified pattern pieces so only unlocked pieces can be edited.
Flip/Rotate	Flip or rotate pattern pieces. Flip updates synchronously in 3D view; rotation does not sync to 3D.
Hide Patterns in 3D Window	Hide pattern pieces so they become invisible inside the 3D window.
Copy/Paste	Generate one or more copies with identical shape as current pattern piece.
Delete	Delete one or multiple selected pattern pieces.
Mirror Paste	Generate a mirrored copy of current pattern shape.

Edit Pattern Piece

Purpose：

Select pattern pieces to edit their lines and points.

Operation Path：

Home ➡️ Edit Pattern Piece ➡️ Select internal shapes ➡️ Right‑click Menu

Line tool	Purpose
Split	Add points and split selected edges into multiple segments.
Add Point to Intersection	Generate vertices at intersections between the selected edge and other edges.
Offset Pattern Outline	Offset partial pattern sewing lines outward by a set distance while keeping remaining sewing lines unchanged.
Change Length	Modify the length of the selected line.
Add as Measurement Line	Mark the selected line as a measurement line.
Add Trims Along the Line	Add trims along the selected line.
Create Internal Shape by Outline	Clone internal shapes inside the pattern based on selected inner or outer edges.
Add Internal Isoline	Generate internal lines parallel to the selected edge.
Add Random Vertical Internal Lines	Create a set of approximately‑vertical internal lines on the selected line.
Duplicated as Mirrored Internal Line	Generate a mirrored‑symmetric internal line for the selected internal line.
Create Guideline	Create a guideline at the current mouse position for pattern‑editing reference. Guidelines provide snap effect for vertices when edges or vertices are being moved.
Lock	Lock selected line segments during line editing so only other lines can be modified.
Paste/Delete Edge	Generate one or more copies with identical shape as the selected segment. Delete one or multiple selected lines. Sewing‑line edges can be deleted but cannot be copied. Deletion will fail if it causes the outline to self‑intersect.

Point Tool	Purpose
Add Notch	Add a notch at the selected point.
Convert to Curve Point	Convert the selected point into a curve point while preserving the curve shape on both sides of the point as much as possible.
Change Angle	Adjust the angle of the selected point.
Create Guideline	Create a guideline at the current mouse position for pattern‑editing reference. Guidelines produce a snap effect for vertices when edges or vertices are moved.
Lock	Make the point unselectable in the 2D view.
Delete Point	Delete the selected point.

	Outer Box Pleat	Two‑way outward folding with raised centre; pleats are visible on outer face.
Number		Refers to the number of pleats.
Interval		Refers to the spacing between each pleat. Lock upper & lower edges to adjust together, or unlock them to set spacing separately for top and bottom.
Width		Refers to the size of each pleat. Lock upper & lower edges for consistent pleat size top‑to‑bottom, or unlock to adjust top and bottom pleat sizes independently.
Length		Refers to the length of pleat lines.
Offset		Refers to the offset distance from both ends of the pleat to the adjacent sewing edges.
