Simplify the configuration of material spacing in assemblies

Users experience difficulties and confusion when they need to set the spacing of materials (e.g., furring strips at 16- or 24-inch intervals, horizontally or vertically) in their assemblies. Currently, the configuration requires the use and understanding of sometimes complex calculation formulas to obtain the correct quantities, which can lead to calculation errors or reversed values. A feature that allows users to intuitively specify the center-to-center spacing of materials without having to create complex manual formulas would greatly improve the user experience.
