In the geometry mating approach, users specify the relative positions of parts by interactively defining spatial relationships between the geometric elements of mating parts. There are six DOFs for each component in space: three translations and three rotations. Kuang-Hua Chang, in e-Design, 2015 4.2.1 Mating Constraints You may go over the lesson to learn more about the model importing capabilities offered by SolidWorks. If you do not anticipate making changes in how these parts are assembled, you may merge all 11 parts into a single part, instead of assembling those using mating constraints.ДЄ step-by-step detail of importing the Pro/ENGINEER part and assembly can be found in the tutorial lesson S1.3. Assembly of all 11 parts (maybe more, for other cases) will be a nontrivial effort. If we do not anticipate making any change to this input gear assembly, this imported assembly is satisfactory, except it does not have any assembly mates. Again, there is no solid feature converted in any of the parts. By expanding any of the parts listed in the browser, such as the gear ( wheel_gbox_pinion_1s), we see an imported feature listed, as depicted in FigureВ 6.17(c). In fact, the assembly and all 11 parts seem to be correctly imported, as shown in FigureВ 6.17(c). The option of importing geometry is also more straightforward for assembly. A nontrivial effort will have to be devoted to reconstructing the solid features (therefore, solid models) as well as the final assembly. However, the Mates branch in the browser is completely empty, implying that no assembly mates have been imported.ДЄpparently, this translation is not satisfactory. The remaining entities are mostly sketches. In fact, there are only two extrude features successfully imported. Major solid features are missing, such as pinion 1 ( wheel_gbox_pinion_1s), whereВ most solid features are not imported. Using the option of importing solid features, parts are not completely imported, as shown in FigureВ 6.17(b). (a) Input gear assembly in Pro/ENGINEER, (b) the translated assembly in SolidWorks using option of importing solid features, and (c) the translated assemblyВ in SolidWorks using option of importing geometry. Assembly import from Pro/ENGINEER to SolidWorks. The 3D contact constraint becomes active as soon as the parts are in contact.ДЇigureВ 6.17. Essentially, 3D contact constraint applies a force to separate the parts when they are in contact and prevent them from penetrating each other. In addition to mates, SolidWorks Motion provides 3D contact constraint, which helps to simulate physical problems involving contacts between bodies. Mechanical mates including cam-follower, gear, hinge, rack and pinion, screw, and universal joint, are essential for motion models yet extremely easy to create in CAD. Advanced mates provide additional ways to constrain or couple movements between bodies. In addition to standard mates such as concentric and coincident, CAD (SolidWorks, for example) provides advanced and mechanical mates, as discussed in Chapter 4. It is extremely important to understand assembly mates in order to create successful motion models. In addition to a prescribed velocity, the motor may be used to drive a DOF at a prescribed displacement, either translational (using a linear motor) or rotational (using a rotary motor). This motor rotates the propeller at a prescribed angular velocity. For example, a rotary motor is created to drive the rotational DOF of the propeller in the engine example. Such a movement is either driven by a motor, resulting in a kinematic analysis, or determined by a force, leading to a dynamic analysis.

In creating a motion model, instead of all movements being completely fixed, certain DOF (translational and/or rotational) are left to allow desired movement. Assembly constraints defined for the engine model (exploded view).
