NX Routing
1 Terms and Definition 1.1 RCP The RCP or Routing Control Point is the point at the start or end of each path segment
1.2 Ports Ports are arrows which mark open ends of Pipelines and are used as connecting points. They are also used as marker whether the parts are connected right or not. Ports disappear if they are connected.
Stock
Path
Port
1.3 Path The Path is the centreline between the RCPs.
1.4 Stock The stock is the pipe attached to the path.
1.5 Overstock The overstock is the insulation for the pipe.

2 Basics 2.1 Fluids Role (only at ECO EN F and SM EN FT) If you start working with NX-Routing it’s recommended to load the prepared Role.
To load the Role, click
-> select the role (see graphic) ->
Warning appears:
-> click ok.
Make sure you Quit NX with „File -> Exit“ after loading the Role. Otherwise changes wont get saved.
2.2 Creating a Routing Path The fastest way is to use „Create linear Path“
-> „Place Dynamik“
With -> „Axis Parallel“ it is possible to draw a path parallel or normal to another path or an edge. And it’s possible to select the endpoint of an edge or path to use the assumptive intersection as endpoint of the new path. To connect two paths or points “Heal Path” can be used. (see 5.3) It’s recommended to use it if the two Objects to be linked are close to each other. Heal Path is a fast solution and also very accurate. (Highly recommended too use for faster working!!!) Always use exact angles, elsewise there will be issues during placing parts.
2.3 Stock and Overstock 2.3.1 Stock To assign a stock, at first the preferences (see Fehler! Verweisquelle konnte nicht gefunden werden.) have to be set up.
To place a stock click
then select the Path, on which stock shall be placed. Chosen stock
-> Specify -> „Routing Part Library“ -> „Rodiks Pipes“-> chose DN -> ok

2.3.2 Overstock 3 To place a stock click
then select the Path, on witch overstock shall be aplyed. Chosen overstock -> Specify -> „Routing Part Library“ -> „Insulation“-> chose thickness -> ok

3.1 Place Part 3.1.1 Select Pipe Specification
Click
-> select Project and Pipe Specification.
3.1.2 Selecting Parts
Click
“Place Part” and select part in the „Routing Part Library“.
To Place Special Parts (Parts not in Library) see 5.1
3.1.3 Place Set Reference Set to “Fluids_Routing”.
3.1.3.1 Place in Path To place select RCP (see 1.1) -> select Placement Solution -> Part angel can be changed with Port Rotation -> confirm The Part is placed correct, if no Ports are visible (see 1.2).
3.1.3.2 Place Part to Part To place, select Port of existing Part, if there is no Port, select RCP. Attention: Rotating Eccentric Reductions will only be possible, if it is placed on a Port!

3.1.4 Create Elbow
With the command , a fence can be drawn to select corners in Part on witch Bends, Elbows and Mitres are placed according to Pipe Specification.
With the command
, Elbows can be removed. Also it is possible to repair “broken Bends”*.
*Broken Bends are Bends which lost the associate to the lines they connect. If the RCP in the Corner of the Bend is Empty, the Bend is broken. (the standard RCP at a corner looks like the one below)

3.2 Placing order of Path and Parts It’s advisable to start with Parts, directly connected to TOP and Connecting Points Attention: - Remove Bows before Transform Path (see 3.5.1) and place them again afterwards. -
Eccentric Reductions are always to be placed immediately, for offset in centreline!
3.3 Build of an Assembly Structure Create FT-Assy. Beneath the FT-Assy Pipes may be placed immediately or more Subassemblies may be added for different areas in the project. To create Pipes use the Pipelist (see 3.4 Pipe list), afterwards Pipes may be moved to different subassemblies Bsp:
To Place a copy of a Pipe, put a copy as Subassembly in the existing Pipe. For Example, see image on the right: the pipe I3-NI-012 in Filter 1 is also a part of pipe I3-NI-032 in Filter 2.
Alternatively “copy as” can be used to create a second version of the Pipe that can be changed separately. In case the new pipe already exists, the pipe, created with the Pipe list tool, has to be deleted from SAP.

3.4 Import Pipe list – FPMD (Fluids Project Master Data) - Fill in Excel sheet
- Click
.
3.4.1 Initial Fill For the first import of the Pipe list to NX use Init Fill. Therefor you have to choose your Pipe list/FPMD with
and click „Init Fill“ -> continue with 3.4.3
3.4.2 Insert Single Pipe
Fill in the F_ID (in FPMD 1_PLH) of the Pipe you want to Import -> click -> Repeat if more pipes shall be added -> continue with 3.4.3
3.4.3 Add Parts to SAP
- Mark created parts in the Assembly Navigator and click
.
- Click „Back“ once, if only one Part is displayed in CAD-Manager. (Except there is only one Part) - Mark all -> Create Document - (change wrong SCS, if necessary) - Save -> UG Check Characteristics -> Save
-
-> Back
- In NX -> Save and Check In

3.5 Modify Path 3.5.1 Transform Path With Transform Path it is possible to move one or more RCPs and Parts. Bends must be removed, before using Transform Path.
To keep length or angles of the Path, they can be fixed by constraints. But be aware that a large number of constraints can influence the performance of Routing. No constraints should be deactivated during modifications of the Path.
3.5.2 Trim (Workaround) To trim a Path segment to another „Create Linear Path“ -> “Axis Parallel“ can be used. Therefor create a second line and unify them with „Simplify Path“ (see 3.5.4) Or create Path with over-length and use Subdivide Segment -> “Through Point” to create an RCP and delete supernatant path segment

NX Routing
3.5.3 Subdivide Segment
Is used to split up path segments and to create a additional RCP on a path segment. The easiest way is to use „At Point“, this gives you 3 options how to define the location of the subdividing Point. (see graphic) „Arc Length“ gives the ability to dig in the length starting at a corner for subdivision. „Through Point“ makes it possible to select the subdividing point per click. It is possible to select either a point on the line, or a line to use the intersection point. „% Arc Length“ divines the subdividing point by dig in percentage of the whole length. The Type „Equal Segments“ makes it possible to divide the segment in multiple parts of equal length.
3.5.4 Simplify Path
Select multiple segments which share one direction to unify them and remove all RCPs except on the endpoints. Only works if the path segments have the same orientation.

4 PCF and ISO 4.1 Creating a PCF for stress calculation Make the assembly, the PCF should be generated of, „Displayed Part“. Set all Reference-Sets to “Fluids_Routing”.
Button
„Transmit PCF-Files to Isogen Server” ->
click Yes ->
click No
After finishing the PCF generation, it is automatically saved in C:\TMP as „PCF_ALL.pcf“.
Rename PCF and copy to project folder.

4.2 ISOMETRIE Erzeugung Create Non-Master Document (for Example ISO001) -> create Component Group of all Pipes for ISO -> open component group -> Button
„Transmit PCF-Files to Isogen Server“ ->
click No ->
click Yes ->
dig in ISO and click ok. (This may take a while) A Folder will be opened automatically, in which the generated files are located.
Save Data in new folder on the project directory. In the non-master doc: Drafting -> Create new Drawing (via “WinSAPdwgUtil”) -> use “Import Part” to import a .prt files (not the …usm000~.prt) -> repeat for all Pipes It is recommended to create an Overview on DRW-1 and start with the ISOs on DRW-2.

5 Tips and Tricks 5.1 Placing non Routing Parts Insert non Routing part via ECTR at any location (but not on End Position)
Click „Place Part“ Instead of selecting a routing part from library, select the non-routing part by clicking on it. -> ok -> Now it is possible to place the part like a routing part. If necessary Trim the stock by hand. Placing non Routing parts may cause issues in Transforming Path, in this case look in 5.2
5.2 Disconnect Part With Disconnect Part, parts may be removed from the Routing Path without deleting them.
Click
move part ->
check box for Disconnect Part ->
select move -> select part to move -> moving the part will delete all constraints and connections to the Routing Path.

5.3 Heal Path
For start and endpoint select either RCP, Path, Port, Point or Axis. Select Stock. In Settings -> Method it is possible to select the order of Axis or “direct” or “Intersection”. As preview for the path to be created, an orange line will appear. -
direct: the Path will take the direct way between the two points
-
intersection: the Path will be created normal or parallel to the selected Axis
-
XC YC ZC: the Path follows the Axis of the WCS in chosen order. (for Example: from start point it’ll go in X then in Y then in Z to the endpoint)
