Assemblies are where the hierarchy and motion are defined between parts. Switch to the CARBURETOR Assembly.
You can insert parts or assemblies from the same or different documents. Insert the new gasket from the CARBURETOR Part Studio.
Mates are how you add relationships between components of an Assembly. Each type of Mate in Onshape defines up to all six degrees of freedom between two components. Each mate is defined with Mate connectors. Mate connectors are a fully defined 3D coordinate system. It has an origin, axes, and a plane on the XY. They are a powerful tool in Onshape, allowing you to define most relationships with just one Mate.
In the CARBURETOR Assembly, take a look at the Mates that are already in place. Several components are held in place by a Group. A Group is not a Mate but is a quick way to lock the orientation of parts with respect to one another by their origin. It is most appropriate for parts built in the same Part Studio because they share the same origin. In this Assembly, most parts are Fastened, but the CARBURETOR_CONTROL_ARM has a Revolute Mate with limits to show its full range of motion.
In the CARBURETOR Assembly, mate the gasket into place with a Fastened Mate.
Mouse over the face and hold Shift to lock the reference. Use the hole center to place the Mate connector. Repeat the process for the MANIFOLD. Select the checkmark to accept it.
Switch to the FUEL AND POWER TRAIN Assembly. Insert the finished CARBURETOR Assembly. Select the Assembly tab to avoid accidentally inserting the Part Studio.
Mate the CARBURETOR Assembly into place with a Fastened Mate. Use Flip primary axis and Reorient secondary access to get the gasket into the correct orientation. By default, Onshape only moves the parts directly involved in the Mate while you are in the Mate dialog. Select Solve if you want to see the final orientation.
Onshape supplies a pre-made library of fasteners and hardware called Standard content.
Open the Insert dialog. Select the Standard Content tab. Choose the standard ISO, Category Bolts & screws, Class Socket head screws, and component Hex socket head cap screw ISO 4762.
Choose the size M5 and a length of 25 millimeters.
Select the 2 holes on the back of the MANIFOLD to place the fasteners. Standard content contain explicit Mate connectors that show even after placing the part. To hide them, use the shortcut: K.
