Garbage in = Garbage out. Everyone knows that rule.

For soft goods this means helping by planning the production. This doesn’t need to be onerous process. In fact it can take just a few minutes and every minute invested can save hours or even days in the production cycle.


Insights in Preparing Your 3D Design for 2D Flattening

  • flatten surfaces not the entire solid (i.e. no thickness needed)
  • define the cut line locations or “3D pieces” before you try to flatten
  • Less is more. Well not really, less is less (less pieces, less seams, less notches, less holes/slot, etc…) and that’s always better.

How To Prepare Your 3D Design for 2D Pattern Flattening

Basic Overview:

ExactFlat pattern Flattening tools expect a 3D Mesh file with specific 3D pieces defined in the CAD file as input.

Complete the following steps each time prior to publishing your 3D model for pattern flattening:

  1. Select Surfaces you want to flatten.
  2. Combine or break the surfaces into 3D pieces.
  3. Remove tiny or extremely small features from you pieces
  4. Convert the pieces to mesh or publish them to ExactFlat

Select Surfaces to Flatten 

The first thing you need to do before you flatten your 3D design is decide which 3D surfaces you want converted into pieces.   There may be many parts or solids in your 3D CAD model.   Just isolate the ones that you want to create patterns for.


Combine Or Cut Surfaces Into Pieces

The surfaces you select may not properly represent the 3D “Pieces” that you want to pattern flatten. To get an accurate representation you may have to cut or combine surface pieces in your existing CAD tool. ExactFlat Software is unique in that it is compatible with the largest variety of CAD programs.

A solid or 3D surface model that makes up an enclosed solid (i.e. a sphere are cylinder) cannot be accurately flattened as is.

Defining the cut lines or Seam Locations can be done as part of the design process in the CAD tool or by using the “Piece Creation” tools provided in any ExactFlat products.

Hint:  While It’s almost always easier to do cutting and splitting of faces and bodies in the 3D CAD tool the integration of design and patternmaking tools provided in ExactFlat Standard and ExactFlat Lite make this part of the  process seamless.

Refine the 3D Mesh used in ExactFlat

Removing holes or small features and refining the mesh using the Adaptive Remesh tools in ExactFlat increases pattern accuracy while dramatically reducing compute times.  Just click on the remesh options to see the tools in action.
