Adding padding can be auto-calculated based on the inside dimensions of your crate or by the outside dimensions of your content. You can see these values from multiple places in the design.  

When you select to 'auto-calculate' your padding, you have the option to chose 'Full Cavity' or 'By Content Size'.

By selecting Full Cavity: Crate Pro looks at the inside dimensions of the crate.

By selecting By content size:  Crate Pro looks at the content size plus the clear area. 

Clear Area: This setting is located in Preferences > Settings. Clear area is used for determining Padding, Wrapping and Floater Decks.

  • When calculating by Inside Dimensions -Crate Pro will assume your content size by taking the Inside Dimensions and subtracting the clear area value. You can manually change the content dimension in any of the Design> Packing content dimension fields
  • When calculating by Content Dimensions - Crate Pro will add the clear area value to the content dimension to determine the Inside Dimension of your crate.

Note: When calculating by Content Dimensions its important to note that adding materials that have a thickness will increase the inside dimension requirement of your crate. Don't forget to click on RUN RULES in the Design> Container > Rules tab to allow Crate Pro to recalculate the required size of the crate with your added materials.
