In this tutorial, you will learn how to assemble a complex assembly from individual parts.
Note that we use the following naming convention in CAD course in assembly modeling:
The name bg_modelname_username should only be used for the entire assembly. All sub-assemblies within the overall assembly are named with ubg_modelname_username. Both the complete assembly and the sub-assemblies may contain individual parts and sub-assemblies.
Overview
In the following you get an overview of the functions covered in this tutorial:
Assembly Navigator | Provides an overview of the subassemblies and individual parts installed within the assembly. The Position column shows whether a part is fully constrained. |
Add Component | Inserts another part into the assembly. |
Make Work Part | Temporarily switches to the single part processing mode in your assembly. In this way, auxiliary geometries can be added to an individual part, which are useful for referencing, for example.. |
Constraint Navigator | Provides an overview of the constraints that have already been set and allows sorting according to various criteria. |
Component Position | |
Assembly Constraints |
Positions components in relation to others. You can choose from the following reference types: |
Touch Align |
Touch: Surfaces are joined in opposite directions. Align: Surfaces are linked in the same direction. Infer Center/Axis: Centered insertion of cylindrical elements, e. g. shaft into bore. When selecting a cylindrical or conical surface, the center or center axis of the cylindrical or conical surface is selected here. |
Align/Lock | This is used to align the axes of cylindrical elements. At the same time, the degree of freedom of rotation of both elements is fixed to each other. |
Bond | This "welds" two elements so that they appear as rigid bodies. |
Angle | Connection through an angle. |
Parallel | Parallel arrangement of e. g. reference planes, surfaces etc. |
Center | Centers one or two elements between a pair of elements. |
Concentric | Concentric arrangement of two bodies. Note that the selected circles are on the same plane. |
Distance | Elements are positioned with a defined offset to each other. |
Perpendicular | Position elements perpendicular to each other. |
Fit | Adds bodies with the same radius into each other. If the radii become unequal, the connection becomes invalid. |
Fix | Provides the possibility to fix a body on the current position. The first component of an assembly should always be positioned with this function (on the coordinate origin). |
Move Component | Moves a part within the assembly by dragging it along the coordinates, if degrees of freedom are available. |
Show Degrees of Freedom | Displays degrees of freedom of a component. |
Others | |
Perform Analysis | Starts a intersection analysis. This means that the module can be checked for existing overlaps (hard touch). |
Override Position | Overwrites the position of an assembly in a parent assembly, thus allowing movement. |
Parts List | Creates a parts list of the installed parts and allows sorting. |
