![]() Now, moving the spindle rotates it without moving it away from the mate point on the jaw. Double-click the Cylindrical Mate to open its dialog and change it to Revolute. This is the way the Cylindrical Mate operates. Finally, click the checkmark to close the Mate dialog.Īt this point, the spindle is free to rotate about the Mate connector and is also free to move along the axis. In these instances, click the Solve button. When the parts snap into position, you may notice that previously added Mates are not solved. Select the point at the rear of the cylinder and repeat the process for the shaft. There are three default Mate connector locations along its axis. Roll over the cylindrical face of the jaw. Revolute removes an additional degree of freedom than Cylindrical does. Next, mate the screw with the sliding jaw. Rotating one of the parts rotates them both. For these Mate connectors, select the point on the face inside the shaft and on the face of the spindle. This Mate type removes all degrees of freedom between any two Mate connectors, so they are bonded together. To fasten the spindle inside the shaft, click the Fastened Mate. For example, use the dropdown to change this Mate to any other Mate type, or to redefine any of the Mate connectors. Double-click to open it and make adjustments to the Mate. The Slider Mate is now listed in the features list. With this single Mate added using Mate connectors, you can remove several degrees of freedom in just a few steps. Notice there are icons to flip the primary and secondary axes in case you need to make any adjustments and obtain the correct results. ![]() Pay attention to the orientation of the triad. To slide this part along the blue z axis of the triad, orient the blue axis normal to the edge of the part and click to snap it into place.įor the second Mate connector, roll over the faces of the other part and the same principle applies. The orientation of the axes is important, particularly for certain types of Mates. In addition to being locations on faces and edges, Mate connectors act as a coordinate system with their own x, y and z axes. When rolling over one of these dots, a small triad appears. These are locations on faces where you establish Mate connectors. Roll your pointer over any face, and small dots appear. Onshape prompts you for a Mate connector. To have this part slide along the base, select the Slider Mate. Onshape defines Mates based on the intended behavior that you would like as a result, such as fastened, revolute, slider, planar, cylindrical, pin slot, ball, and parallel. Any part that is fixed has this icon next to it in the features list. To do this, right click on the part in the graphics area or features list and select Fix. First, fix one of the parts so that it removes all its degrees of freedom, so all other parts are mated with respect to it. All the parts are completely free to move and have all their degrees of freedom. Switch over to this empty Assembly tab and insert everything from the Part Studio.
