Sample Code

The following is a list of code samples available to HOOPS Exchange developers. These samples are short applications that demonstrate a specific functional topic. The source code for each sample is distributed as part of the HOOPS Exchange package. The sample sources are located at <exchange_install_dir>/samples/exchange/exchangesource/. Before running each sample, you must first build it. Visual Studio project files and Linux makefiles are included.


B-Rep adaptor

samples/exchange/exchangesource/BrepAdaptator

This sample demonstrates how to programmatically adapt B-Rep models to particular needs using HOOPS Exchange. The only input is the CAD file path.


Cascaded attributes

samples/exchange/exchangesource/CascadedAttributes

This sample demonstrates how to programmatically set the mechanism of the cascaded attributes using HOOPS Exchange.


Collision Detection

samples/exchange/exchangesource/Collision

This sample illustrates the collision detection feature in HOOPS Exchange. The sample reads an input CAD file and outputs collision status between representation items. The user may select which items are tested using their UUIDs; the output is available as a report file.


Create PRC B-Rep with geometry

samples/exchange/exchangesource/CreatePRCBrepWithGeometry

This sample demonstrates how to programmatically create a PRC file using HOOPS Exchange. The only input is the file path. The program generates a PRC file which contains a tessellated textured cube and a simple markup.


Create PRC cubes

samples/exchange/exchangesource/CreatePRCCubes

This sample demonstrates how to create a PRC file with the Exchange API. The only input is the output file path. The program generates a PRC file containing a tessellated textured cube that is instantiated multiple times. The generated output also contains PMIs and Views, as well as links between markups, Views, and entities.


Drawing viewer

samples/exchange/exchangesource/DrawingViewer

This sample demonstrates how to programmatically visualize a drawing PRC file from a basic OpenGL program using HOOPS Exchange.


DumpFeatureTree

samples/exchange/exchangesource/DumpFeatureTree

This sample demonstrates how to traverse a model and capture its features in an XML file.


Import-export

samples/exchange/exchangesource/ImportExport

This sample demonstrates how to programmatically import a CAD model using HOOPS Exchange and convert it to another format.


Incremental load

samples/exchange/exchangesource/IncrementalLoad

This sample demonstrates two ways of loading a CAD file: normal loading and incremental loading (first the assembly tree, then the parts contained in the file). Using the incremental loading technique allows a more fine-grained approach, which is especially beneficial when dealing with huge files (e.g., for loading only specific items at a time rather than the whole file in one shot). The only input is the file path.


Load CAD file with multiple configurations

samples/exchange/exchangesource/LoadMultiConfigCADFile

This sample demonstrates how to programmatically load CAD files that contain multiple configurations using HOOPS Exchange. The only input is the file path.


Import multiple PRC files

samples/exchange/exchangesource/MultiplePRCFiles

This sample demonstrates how to programmatically create and read multiple PRC files from a CAD assembly using HOOPS Exchange. The input is the CAD assembly file path and a directory. The program generates multiple PRC files from this CAD assembly.

This mode is supported for the following formats: V4, V5, ProE, UG, SLDW. With other formats, only one PRC file is generated.


.NET wrapper

samples/exchange/exchangesource/NetWrapper

This sample demonstrates how to use HOOPS Exchange with a .NET wrapper by converting any CAD file to XT.


PRC to XML

samples/exchange/exchangesource/PRC2XML

Converts a PRC file to an XML representation.


Sew B-Rep

samples/exchange/exchangesource/SewBrep

This sample demonstrates how to programmatically adapt B-rep models to particular needs using HOOPS Exchange. The only input is the CAD file path.


Shattered

samples/exchange/exchangesource/Shattered

This sample demonstrates how to use the shattered mode in HOOPS Exchange. The input is the CAD assembly file path and a directory. The program generates multiple PRC files from this CAD assembly.


TranslateToPkParts

samples/exchange/exchangesource/TranslateToPkParts

This sample demonstrates how to use the Parasolid bridge in HOOPS Exchange to send the converted CAD data to Parasolid and then use the Parasolid APIs to perform advanced functions on the geometry, like healing, merge, simplify, sew, or accurate edges. The input is the CAD file path and a directory plus the options. The program generates a Parasolid file from this CAD file. Please note that this sample won't compile right away, specific things (detailed in the header of the source file) related to the Parasolid setup need to be done before running it.


Viewer

samples/exchange/exchangesource/Viewer

This file demonstrates how to programmatically visualize a PRC file with a basic OpenGL program using HOOPS Exchange.
