SOLIDWORKS 2019 What’s New – Bounding Box in Assemblies – #SW2019

With the SOLIDWORKS 2019 release just around the corner, here is an article on some new Assembly level functionality building on last year’s release of Part Bounding Box. New for SOLIDWORKS 2019 is an assembly level Bounding Box feature. Basically with any assembly file that contains geometry, you can create a Bounding Box which calculates a minimum volume of that geometry. It is important to note that an assembly can contain only one Bounding Box feature.

To use this new feature, select the Reference Geometry toolbar button from the Assembly Command Manager toolbar, and click on Bounding Box. This will launch a Bounding Box Property Manager with several options.

From this Property Manager, you can choose a ‘Best Fit’ or ‘Custom Plane’ orientation for this Bounding Box. The above image shows a Preview of the Best Fit method. Choosing Custom Plane allows you to select geometry to align the edges of the Bounding Box placement.

Some other options include:

  • Include Hidden Components: Includes hidden components in the bounding box calculations
  • Include Envelope Components: Includes envelope components in the calculations
  • Include Hidden Bodies: Includes bodies that are hidden at the part level in calculations
  • Include Surfaces: Includes surface bodies in the bounding box calculations
  • Show Preview: Displays a preview of the bounding box in the graphics area

Bounding Box calculations show up automatically at the Configuration Specific Properties area of the assembly file. These include Length, Width, Thickness and Volume.

You can now add Bounding Box features to your Part models, which show up as a Green color. You can add Bounding Box features to your Subassembly files which show up as Blue. And finally in your top-level assembly files as a Gray color.

In the active assembly, the Bounding Box calculations do not update dynamically when the components change. A rebuild icon will appear next to the Bounding Box feature when you need to recalculate.

I hope this part of the What’s New series gives you a better understanding of the new features and functions of SOLIDWORKS 2019. Please check back to the CATI Blog as the CATI Application Engineers will continue to break down many of the new items in SOLIDWORKS 2019. All these articles will be stored in the category of “SOLIDWORKS What’s New.”

Other Tips for writing the Blog from Word:

  • Avoid any weird formatting.
  • Crop images before inserting them into Word, any cropping in Word is removed when importing into WordPress
  • Keep your article left justified.
  • Do not try to wrap text around your pictures just put them on their own line.
  • These articles are for existing customers, but prospects will also see them.
  • On shorter topics, compare it to past releases and give use cases for the new/improved feature
  • Bold SOLIDWORKS and use the full name of the products i.e. SOLIDWORKS Composer or SOLIDWORKS Flow Simulation

When posting your article make sure to grab the appropriate categories, the main ones are SOLIDWORKS What’s New and Daily Dose…of SolidWorks Support, but make sure to grab any additional ones that make sense.
