Problem:
How do I modify a piping segments in AutoPIPE?
Solution:
Please see the following AutoPIPE help section:
Help > Contents> Bentley AutoPIPE> Contents Tab> Command Reference> Edit Commands> Segment>
Segment Hide Selected
Useful to remove some segments which clutter the model
Segment Hide Unselected
Useful to isolate a few segments only to view and work on in the model
Segment Show All
Useful to quickly view the complete model
Segment Reorder
Allows reordering segments in custom / automatic order
Segment Reverse
This is very useful when importing CAD models, when often the sequence the CAD model was built in a unorganised manner. Reversing segments also improves the ease of working with a model (e.g. imported from CAD), such as inserting components in a ’forward’ segment direction.
Segment Split
Operations like split segments enables users to easily model piping which is or not subjected to wind loading e.g. indoor vs outdoor piping into one single model. It can be used to 'Break' the model
Segment Join
Merging segments allows less segments and simplifies the model when segments have been reconnected back at junction/continuation points
See this page for Rules / Limitation on joining segments
Note:
1. See TEE Modeling Approaches WIKI here
2. There are multiple rules associated with joining segments. Please review them all in AutoPIPE help.
Known issues with Joining segments:
a. Parts of line disappear after joining
Renumbering a Segment
Enables the user to renumber the points in a single or multiple selected segments
How to add a Segment.
Adding a new segment is not apart of the segment modification commands mentioned above. This is akin to inserting a new segment to then add additional node points to it. To start adding a new segment one must make an existing node point the active point (Ex A00). Now start the insert Segment command (use the Search feature to locate the command).
The following dialog will appear:
Here is when you will need to decide exactly how that segment is to be added to the Model:
1. Will the segment be attached to the current node point?
2. Will the segment be placed relative to the active point?
3. Will the segment be placed relative to model's Origin point?
See the following respective instructions, paying special attention to the global offset values in each scenario:
Segment attached to the current node point
Name of first point remains as is, adjust the Pipe Data identifier as needed or leave as is. and Press OK button.
Next notice that the active point is still the same (ex. A00), however notice that the active segment is now changed (ex. C)
.
Continue to insert Runs and Components as needed.
Segment placed relative to the active point
In this scenario, insert the same piping as indicated above but starting at a location (DX= +2.00) relative to the active node point (ex. A00).
Start the Insert Segment command. This time, the first node point is not going to be the active node point (ex. A00) but a new node point generated in space (ex. C00). update Name of first point to a new node name (ex. C00) not in the model, next Insert the name of node point offset will measured from (ex. A00 - active node point), then enter the amount offset from that point to the Origin point of the segment, and finally modify the Pipe data; then press the OK button
Again, Continue to insert Runs and Components as needed.
Segment placed relative to model's Origin point
In this scenario, insert the same piping as indicated above but starting at a origin point of the model
Start the Insert Segment command. This time, the first node point is not going to be the active node point (ex. A00) but a new node point generated in space (ex. C00). update Name of first point to a new node name (ex. C00) not in the model, next Insert the name of node point offset will measured from (ex. use O as indicated on the dialog), then enter the amount offset from that point to the Origin point of the segment, and finally modify the Pipe data; then press the OK button
Again, Continue to insert Runs and Components as needed.
| Connecting Segment Scenarios |
Scenario #1: Connect Reducer to run
Objective: connect reducer segment (seg E) to run piping (seg C)
Solution:
In this case the reducer was found to be the first point in the segment.
A reducer component really needs to have a pipe run before and after it in order to correctly define the end points pipe sizes. This is one way of connecting the Blue piping to the Green piping.
Step #1: Select the previous pipe node point on the Blue pipe segment, ex.C12 , to make it the active point
Step #2: Insert a new node point, ex. E13, before the end of the Blue segment,
Step #3: Delete the last node point on the Blue pipe segment, ex. C11, and make the first node point on the Green Pipe the active node point.
Step #4: Determine the direction of the Green pipe segment (was found that E01, was the start of the segment).
Step #5: Insert Run before the reducer connecting to the previous node point created on the Blue Piping segment.
.
Step #6: Use Segment Join command at the junction of the 2 segments.
Step #7: Delete temp point, ex. C13
Step #8: Done
