Here's how you can build a 20x40 tent using two 20x20 tents already in your inventory.
**This method can be used for any larger tents that are built of several, smaller tents**
The image below depicts how to edit the "Contents" within your 20x20 tent package once created.
Next, build your 20X40 tent in your Packages section and add your 20x20 tent as "Contents".
When you add the 20x40 Package to your project, two 20x20 packages will be added. This will add the correct number of parts needed for a larger 20x40 tent.
