Plans include PDF plans with all measurements and a complete SketchUp file.
The PDF file can be printed off and has all the information you could need. If you find yourself wanting more information, you can open up the SketchUp Model and get absolutely everything you could want.
SketchUp is free and can be downloaded to view and manipulate the model to give you all the information you could possibly need.
If you are unable to complete the purchase through Stripe, you can send me payment through PayPal to firstname.lastname@example.org. Include the email address you'd like them sent to and which plans you want. I will send them to you as soon as I can. This should only be done if Stripe fails multiple times.
