Bottom-Up 3D Assembly Design |
|
Assembly design based on the "Bottom-up" principle implies the creation of assemblies from 3D fragments. At the same time, it is assumed that the main work on creating models of parts in separate files has already been carried out and it remains only to include them in the assembly.
The command for inserting a 3D fragment is Insert 3D Fragment. The command is called as:

Rules for working with 3D fragments
To insert a 3D fragment into an assembly, you need to do the following steps:
1. Select 3D fragment.
The selection is done by one of the following ways:
•insert a new 3D fragment by selecting a file;
•select an already inserted 2D fragment and use its three-dimensional model.
•if the symbol of the model file is dragged from the Windows Explorer or from the service window of the T-FLEX CAD libraries to the 3D window, the 3D fragment insertion command will be started automatically and the given file will be selected for insertion.
2. Select or Create Source LCS for the fragment. Selection can be done automatically if the 3D fragment has exactly one or a specially designated LCS.
3. Select or create target coordinate system in the assembly.
4. Define the values of the fragment external parameters.
This step is skipped when using an existing 2D fragment or if the 3D fragment does not have external variables.
The values of the variables can be set automatically upon attaching 3D fragment to the connector of another 3D fragment.
5. Define fragment parameters (optional).
6. Finish input.
