SyncroFIT® Product Tip

 

SyncroFIT® Provides the Flexibility to Display Fastener and Hole Information with the Appropriate Level of Detail

Engineers need to visualize airframe assemblies differently throughout the development process depending on the task that is required.  SyncroFIT® provides several options to do this, resulting in an unprecedented level of flexibility and efficiency throughout the entire process.

During the assembly design and fastener layout phase, simple point and vector representations of fasteners are sufficient to communicate key information quickly—such as fastener location, head side, spacing or distance to edge—while minimizing model size.

At other times, cylindrical representations of fasteners are necessary for engineers to easily visualize fastener lengths and rough interferences without bogging down computing power.

But if the task is to perform complete clash/interference detection, maintenance studies or installation studies, or if it is a required supplier deliverable to the OEM, it is necessary to load fasteners into the model so all the hardware at every location can be seen, including nuts, washers, nut plates, etc.

SyncroFIT provides numerous options for representing fasteners, including:

  • Point
  • Point and vector (highlighting and permanent geometry)
  • Simple cylindrical solid
  • Actual hardware models
  • Installation tooling clearance solids
  • Full size/coordinating/pilot holes

Benefits of each:

1. Point – A point is the simplest representation of a fastener location, which is all that is required for SyncroFIT to capture a complete hole and fastener definition. This basic visualization level is the lightest weight option for optimum memory usage when managing assemblies with numerous fasteners.  To help organize and identify fastener and hole information, the point color, style, and size can be manipulated.

Point

Different fasteners are identified by a point’s color, style and size.

2. Point and vector – The point and vector method is another way to visualize the fastener while saving memory and speeding up performance.  Engineers have the ability to simply highlight fastener locations with this representation or create a permanent point and vector.  The permanent geometry is pushed out to the CAD model specification tree and organized in a geometric set that is named according to all fastener hardware.  Data in the tree can be easily updated with a single command after design changes occur. This data can be used downstream to communicate information between other departments in the enterprise. 

Color, style, and size can be adjusted from the fastener location, allowing engineers to easily identify matching fasteners and understand when grip lengths change.

Point and Vector
The point and vector style, color and size identify the different fasteners in an assembly.  Vector length can be adjusted to reflect the actual stack-up length.

3. Simple cylindrical solid – A cylindrical representation of a fastener can be loaded as a body within an assembly or installation model to support basic collision detections and enhance visualization.  Head side extension, tail side extension, and color adjustments can all be made from the fastener location. 

Simple Cylindrical solid

 Simple cylindrical solids assist in basic collision detection.

4. Actual hardware models – The actual solids of fasteners and associated hardware can be loaded from a library of standard parts when the true representation is desired.  SyncroFIT loads the models without requiring the end user to manually assemble each fastener component.  All hardware can be loaded at the root level of the assembly, within a CATProduct, or within a component set.  This method allows several pieces of information to be generated: Bill of Material quantities, collision detection, weight, and downstream DMU assembly simulation/electronic part identification.

5. Installation tooling clearance solids - Clearance solids representing an installation tool or other clearance envelope model can be loaded on the head or tail side of the fastening system.

The ability to see fastener/hardware/tool representations allows for quick visualization of assembly requirements, identification of installation problems, and an understanding of tooling requirements.

6. Full size/coordinating/pilot holes - User-defined hole specifications are applied to each fastener location to define the critical information to convey drilling requirements.  Due to different hole specification methods in the industry, VISTAGY has developed a very flexible means of supporting the various approaches, such as creating modeled hole features in the detail parts of the assembly, in addition to creating holes as final flight definition and/or pilot-coordinating.  This information can be used to drive drilling machines and fastener installation machines.

Full and Pilot Holes

Changing the fastener representation is easy!

Creating, updating, and removing any of the fastener representations can be done with a single command.  Engineers can easily group and change representations as well as toggle the display on or off.  It takes only minutes to change massive amounts of data with SyncroFIT, which can take days using a manual process.
