If you choose Distance Fixed, enter a value below for Max. distance between rafters.
If the user-defined range might not allow the regular placement of the objects. In such a case, use the Distance Fixed - gap start/middle/end radio buttons to fine-tune where the gap between rafters will be introduced (either at the start, the middle or the end).
