Markings

Markings

The ExactFlat Markings tool allows the user to draw sketches on ExactFlat pieces.  Markings can be used to enable functionality in Costing, Nesting  and Export. Marking Features allow the user to define the functionality of the marking in the ExactFlat Database. Marking Types allows the user to control the functionality of the Marking Feature.
Marking Features
An ExactFlat Marking Feature allows the user to create a standard feature for all users of the database.   Marking  color, linetype, actions  and export layer can be specified.  Assigning a Marking Type to the feature allows the user to add functionality to the marker such as Mirror Lines and Quality Zones.
Marking Types
Marking Types allows the user to control the functionality of the Marking Feature.
  1. Sew Lines: The Sew Line   type allow the user to identify sew lines internal to a piece.  Marking Features of this type can have actions assigned.  All line entities within a sketch will be used in labor cost calculations.  Points, blocks and reference geometry can be used in the sketch,  however these entities will be disregarded for cost calculations.
  2. General Markings: General Markings  type allows any type of sketch entity to be applied to a piece.   Typically these features are used to attach internal sketch geometry to a piece.  If internal geometry on the piece needs to go to separate layers,  multiple Markings Features can be created in the database to facilitate this.
  3. Quality Zone: Quality Zone Marking Types allow the user to identify quality zones internal to a piece.  Marking Features of this type require the user to identify regions within a piece.  Sketch entities must contain closed loops.  Only one Quality  zone per feature instance can be specified.
  4. Annotation Text Markings: Annotation Text Markings  type allows text entities to be applied to a piece.   Typically these features are used to attach text that is intended to plot onto a piece using a CNC cutter.  This feature allows the user to indicate adjacent edges, piece information text or fabrication instructions.  Geometry such as lines or arcs can be added to the Annotation Text.  Construction geometry can be used in the sketch,  however it will not be transferred to the piece when exported.
  5. Turn Points Markings: Turn Points Markings type allows the user to define points were a cutter would typically lift and plunge cutting tool when making a corner.  Sketch points defined on cut perimeters can will be recognized as turn points.  All other geometry will be disregarded.
  6. Grade Reference Lines :Grade Reference Line Markings  allow the user to attach reference lines that indicated a common origin, direction and scale for pieces sizes.   Typically these features are used when exporting apparel patterns to outside CAD systems.
  7. Mirror Lines:  A Mirror Marking  allows the user to specify an axis of symmetry to be passed to the Nesting Environment.    Theses lines are typically used if a symmetrical  piece is intended to be placed on a marker fold line.
  8. Lead in Points: Lead in Points Markings  type allow the user to define where a cutter begins and ends a cut perimeter.  Lead in points are recognized by the nester to provide clearance around these points when creating a nest.
  9. Lead in Path: Lead in Path Markings  type allow the user to define where a cutter begins a cut perimeter.  Lead in paths are recognized by the nester to provide clearance around the path  when creating a nest.

Multi-Piece Sketch Assignment

New to Service Pack 3 is the ability to assign a sketch (hardware, marking, drills, etc.) to multiple ExactFlat model or pattern pieces.  A reference sketch will be created for each piece being targeted, and the geometry will be optionally trimmed to the perimeter of the targeted pattern piece. When using multi-piece sketch assignment on model pieces as a 3D to 2D marking, a tolerance value can be used to limit the maximum allowed distance from the source sketch elements to the targeted pattern piece. All elements beyond the tolerance will be ignored when creating the reference sketch.

Once a sketch has been created, the Sketch’s pattern piece assignment can be changed in either model or pattern view. Additionally, the trimming and tolerance parameters can also be changed from any view.

Deleting one of the reference sketches from pattern has the same effect as removing a pattern piece as a target for that sketch.

Deleting the source sketch will remove the ExactFlat hardware, marking, etc., but leave the reference 2D sketch in the document. The reference 2D sketch can be safely deleted if it is no longer required.
