Question
How to define a main constraint path in assembly unit library type?
Answer
In CIM, for creating any advanced library type, such as a combination of lateral beams a function
Main Constraint Path is available. This allows a user to add multiple objects in a single library type, with the help
of references called as path in CIM terminology. An example of defining these paths is highlighted in the steps
below.
In the Assembly Unit Library type, the main constraint path can be found in the interface as shown below.
Step 1 - In the interface, click on the arrow pointing downwards on the Path icon.
Next, a drop down menu appears.
Step 2 - Click on Main Path icon.
The Main Constraint Path property tab appears, now we choose the planes from the model space.
Step 3 - Use the cursor to select the constraint planes simultaneously.
The constraint plane sub function highlights as 2 selected for confirmation of plane selection and the path is
illuminated. Now, in the Offset function enter the value for defining direction and coordinates for the new
path to be added.
Step 4 - Enter value 5 with default unit as meters (m)
A new path to be placed is illuminated in positive Y direction and at an offset of 5 m from the default path.
In the last step,
Step 5 - Click on the green tick to apply and close the command.
A new Main Constraint Path appears in the model space at offset of 5 m in the Y direction shown in the image
below. Similarly multiple paths can be defined in the assembly unit library type as per modelling requirement.
