What are some basic tips to making a stable assembly?
There are many considerations that must be addressed when starting an assembly. There are also several methods and philosophies to address these considerations. This answer only provides general recommendations without getting into specific methods. Planning is important to making a stable and useful assembly. When starting an assembly, align the primary parts solid model origin to the origin of the assembly model. However, instead of mating to this origin, the solid model should simply be set to Fixed. Reorientation of the assembly may be difficult if the part solid models are dependant on the assembly model reference geometry (origin, default planes). The primary part should be either: A base part to which most other components are mated (such as a base plate) The most functionally important part to which most of the other components must be related. (In this case, it is also important to make sure the parts origin is at the most functional location within that parts solid model.) Ma
