SpeedPak creates a configuration that can simplify an assembly or subassembly without losing references. If you work with very large and complex assemblies, using a SpeedPak configuration can significantly improve performance while working in the assembly and its drawing.
SpeedPak can be used when you want to insert a complex large assembly into a higher level assembly, especially if you want to see the entire assembly, but only need to mate and dimension on relatively few locations.
SpeedPak from the Configuration Manager
- For example, you design an engine assembly, and need to send it to your customer’s design team so they can insert it in their vehicle design.
2. You create a SpeedPak configuration of the engine assembly, including all the faces, bodies, reference geometry, sketches, and curves your customer plans to reference in their vehicle model.
3. To create the SpeedPak configuration, you may go to configuration manager and right click on any configuration you want to use and select Add SpeedPak:
4. Then on the PropertyManager:
a. Select the faces, bodies, reference geometry, sketches, and curves that you want to be selectable in the SpeedPak configuration.
b. Optionally, select Remove ghost graphics to hide all other faces, which improves performance.
5. Click OK when done selecting entities and body that needs to be include for viewing and mating purpose. A SpeedPak configuration is created as a child of the original configuration. It is identified with and _speedpak is appended to its name.
6. No components appear in the FeatureManager design tree. The assembly icon at the top of the tree indicates that the active configuration is a SpeedPak configuration.
7. Thus, this file can be saved and send to your customer for their use. You can send just the assembly file and do not need to include component files. They can insert your engine assembly file into their vehicle assembly file. They also can add mates and dimensions to all the items you included in the SpeedPak definition.
SpeedPak from Top Level Assembly
Another situation is when you have one large assemblies but some of the subassembly you do not need to use their information and wants to have faster process and performance.
- In an assembly, right-click on one subassembly that you want to simplify and select SpeedPak Options
2. There are 2 available types of SpeedPak with this technique as summarized below:
|Mated SpeedPak||Includes mated faces, edges, and points as resolved geometry, which allows you to create other mates to those entities. Entities included as resolved geometry include entities of the subassembly that mate to other components in the open parent assembly or to the open parent assembly itself.|
|Graphics SpeedPak||Lets you see graphics for the subassembly but does not include any resolved geometry, which yields more performance improvement.|
3. For example when you use Mated SpeedPak, you will see the geometry is unavailable for selection. Only the faces used in mates are selectable.
*Note: The ghost circle for SpeedPak can be toggled on and off by pressing Alt + S. It can also be disabled through Options, System Options, Display, and clearing the checkbox for Display SpeedPak graphics circle.
