Q : What does it mean to “Branch and Merge(合併)” a design in Onshape?
A : Generally speaking, “branching” and “merging” are tools used in concurrent design, where design variations are investigated(研究) at the same time. A “Branch” represents one of the several design options, and a “Merge” is when two design options are combined, where the result has the design features of both options.
