Crate Pro 6 allows you to change the value of any field. For example, in the design you want to change how a cleat is calculated, you're able to click in the field and either add the correct value, or you may chose to add or modify the existing calculation.
If you add a value only then should you change the dimensions of the crate, the entered value will not recalculate. By entering a new calculation, changes to dimensions will update the value based on the calculation.
You can modify any field with a calculation even the initial dimensions entry for your crate design.
To return any field to the original calculation, click in the field and either Backspace or Delete on keyboard
