Edge Features

Edge Features

Edge Features are modifications to the edge of a piece.  Typically this involves adding material to an edge to provide for sewing allowance. Feedback such as the sewing start location, and the difference in length between edges  is giving on screen and in the property manager page.

Production information such as the type of seam and manufacturing sequence can be defined in the Edge Feature. Watch the video below to learn more:

Edge Links

Edge Links  are required in order for features such as Notches  , Find and Costing to function properly. ExactFlat automatically creates edge relationships if  a piece is developed from a solid body or a knitted surface bodies.   Adjacent edges are tracked such that adding an edge property on a piece will add the same edge property on the adjacent piece. Edges are automatically inked if pieces share an edge in a 3D model. If edges are not coincident in a 3D model,  a relationship between edges can be added manually.  Watch the video below to learn more:

  • Seams

The ExactFlat Seam  tool  allows the user to add material to both sides of a pattern piece. Notch Chains, Independent Notches   and End Conditions can also be controlled using the Seam tool.

  • Bound Edges

Bound Edges  are similar to a seam feature,  however material can be applied to the edge.

  • End Conditions

End Conditions are chamfers (mitres) applied to an edge  at the endpoints.  The chamfer may be determined by the adjacent edge or neighboring piece.

  • Hardware

The ExactFlat Hardware  tool allows the user to utilize sketch information to help develop a Bill of Materials. Hardware sketches can be used to transfer sketch data to cut files similar to Markings.

Seam Construction

ExactFlat Seam Constructions are applied to Edge Features.  Seam Constructions allow the user to specify the  method by which edges of sewn products are fabricated.   When used properly in Edge Features,  seam constructions allow the user to communicated the orientation of all pieces being joined, along with the direction of sewing.  A list of standard constructions along with predefined graphics are provided with the ExactFlat software. Following the conventions here will allow the user to quickly communicate edge  fabrication details.

In the example below we will illustrate a seam formed by superimposing two lies of material.  In this seam construction, the face sides of the material are placed against one another during fabrication (normals opposite).   One is then turned over such that normals are facing the same direction.    A second line of stitching is then applied such that the seam allowance is stitched to one of the pieces
Pieces 1 and 2 are viewed adjacent to one another as they would be designed in the 3D model.  The pieces meet at stitch line A.  A second line of stitches form stitch line B.
Seam start and stop are indicated by green and red icons appearing at the ends of the Edge Feature
