SOLIDWORKS 2019: Bounding Box for Assemblies

Categories // What's New In SOLIDWORKS

What's New in SOLIDWORKS 2019

The Bounding Box is a feature within an assembly which contains geometry and is calculated using the same methods as the part level bounding box. While you can have a bounding box in an assembly, you can only have one. Once the bounding box is in the assembly and you right-click, you are given the four options of Hide, Show, Suppress and Unsuppressed.


SOLIDWORKS has, however, made it easy to tell what is going on within the bounding box as they have color-coded depending on the location of the item in the assembly.

  • Top-level Assembly bounding box = Gray
  • Subassembly bounding box = Blue
  • Part bounding box = Orange

To view a bounding box, click View Bounding Box on the Assembly tab under Reference Geometry in the Command Manager. When you want to view the properties of the bounding box, either hover over BoundingBoxIcon1the Bounding Box in the feature manager (icon at righ) or you can click to the following location: File > Properties > Configuration Specific. Within the properties, you will find the values for the Length, Width, Thickness, and Volume of the bounding box.


Let’s get a bit further into the nitty gritty of the Bounding Box feature. 

The calculations for the Bounding Box include SpeedPak faces and bodies but not the SpeedPak ghost graphics. Once the bounding box has been created within the assembly, you can add a SpeedPak subassembly into the current assembly or change an existing one already in the assembly or subassembly. However, it should be noted that in an active assembly the calculations do not update dynamically and, when a rebuild is needed, the rebuild BoundingBoxIcon2icon (icon at right) will appear to let you know an update is required. Another thing to note in regard to the bounding box, is that the time required to calculate a bounding box feature is included in the Assembly Rebuild Report. Should you need to access this report, you can locate it in Tools > Evaluate > Performance Evaluation and simply expand the Rebuild Performance section of the report.
