Why recipes?
There are some operations using replicad (or any CAD tool) that are at the same time very common - but have many different configurations and edge cases.
In tools with a UI, this translates to very complex configuration boxes with multiple options that do not work well together most of the time.
In a code CAD tool like replicad, this would translate to a function with a very complex signature.
In some cases - the basic logic behind this functionality is fairly simple – but the different tweaks possible add the complexity.
Instead of offering these as a standard library with a complex interface, I propose a recipe book of code that can be easily copied and tweaked to your particular needs.
