Building Assemblies from a Graphics Gallery or a 3D Model

Given a graphic asset, or 3D reference model, Vortex® can generate the dynamics components (assemblies, parts and collision geometries) to match.

  1. If you are not already in the Mechanism editor, either open an existing mechanism or create a new one.
  2. Insert an empty Assembly (.vxassembly) file.
    This assembly will hold the parts built from the graphic asset (to be imported in the next step).
  3. Do one of the following:
    • Insert 3D models through a Graphics Gallery (recommended).
    • Select Graphics in the Toolbox, then double-click 3D Model....
    The Add Graphic Assets panel appears.

  4. Do one of the following:
    • Find the graphic asset file you want to use under the File System section and double-click it.
    • Click the Browse button under the File System tree and double-click the graphic asset file you want to use.
    Valid asset file formats include *.flt, *.osg, *.ive, and *.cive.
    The 3D model appears in the 3D View and you can now find the node tree for the model under the Explorer panel.

  5. For each part you want to create, follow the instructions under Building Parts from a 3D Model.
  6. When you are finished creating parts, click Save All.
    When Vortex saves the mechanism file, it creates the new Graphics Gallery, assembly and part files automatically. From then on, the mechanism knows about which files it owns so that when you make a change in the Graphics Gallery, assembly or parts it will be updated automatically.
    The naming convention for Graphics Gallery, assembly and part files created in this way is <mechanism_name>_Gallery.vxgraphicgallery, <mechanism_name>_Assembly.vxassembly and <mechanism_name>_<part_name>.vxpart.
    Warning
    If the graphic file is not found, no graphic will be loaded. An error might occur during runtime simulation causing the simulation to not run properly.
