Problem:
How to model a Guide support mounted to another Guide Support?
Example: The smaller pipe guide is connected to the larger pipe Guide.
Assumptions:
a. Rod hanger clamp on the large-bore pipe is rigidly connected to the pipe, no axial movement of the pipe through the support.
b. The support on the small-bore pipe is rigidly connected to the large-bore pipe. However, the large-bore pipe moves, so does the small-bore pipe.
c. Support on the small-bore pipe to allow axial pipe movement.
Solution:
Please open a guide support dialog, and notice the "Connected to" field.
Position your cursor within this field, press the F1 key on your keyboard, and review the information regarding this feature.
With a comprehensive grasp of the "Connected To" feature, one can now recognize that a support can be linked to one of three locations (for instance, 1. Ground).
Modeling Approach
1. Model the large-bore pipe as needed (ex. B01 - B02).
2. Model the small-bore pipe as needed (ex. C45).
Note: In this example, the rod hanger will be connected to B01, and the support at C45 will be connected to B02.
3. On the small-bore pipe, ensure a node point is directly adjacent / in line with the large bore "Connect to" point (ex. C45 and B02 have the same Z-axis coordinate)
4. On the small-bore point, insert a Guide support who's "Connected to" point is the corresponding node point on the large-bore pipe (Ex. B02).
5. Model the Rod hanger (ex. B01).
6. Done.
Note, if one wants to rigidly connect the small-bore to the large-bore with both supports not allowing any axial pipe movement, then connect the 2 node points (ex. B02 - C45) with a beam element. Now the 2 are rigidly connected.
