Plant Engineering > New > Pipe part 
Pipe parts are parts that can be part of a pipeline. They can be aligned and positioned using guidelines. The dialogue shown is displayed for the insertion of pipe parts. In this dialogue window you have full control over which search criteria are used to search for a part.
Part search
Active pipeline
The name of the active pipeline is displayed in the upper area of the tab. Newly added parts will be subordinated to this pipeline, provided there is nothing to the contrary, e.g. the placing of a part on a guideline. In such a case, the part must be assigned to the same pipeline as the guideline.
You can change the active pipeline within the dialogue. To do this, click on the 
symbol and then select a pipeline in the drawing or in the ICN.
If you click in the name field, the active pipeline is highlighted in the drawing. Clicking again removes the highlighting.
Displaying and selecting the active pipeline in the dialogue makes it easier to connect parts to existing pipelines if the new part to be inserted is to be assigned to another pipeline.
If you want to define the pipeline assignment depending on the connecting point (standard behaviour before HiCAD 2022 SP1), click on the symbol. The 
symbol changes to 
and the active pipeline is no longer fixed but follows the connecting point.
Also note that the pipe class suggested in the search criteria now follows the active pipeline.
Part type / Search criteria
First select the part type that is to be installed. If you have defined your own part types, e.g. valves, an arrow symbol is displayed next to the corresponding part type. Click on the symbol to display a list box with the corresponding part types.
After selecting the part type, the search criteria will be narrowed to those constraints that make sense for the selected part type. With a click in the drawing, the default search criteria (left column) can also be filled in.
For each search condition there are now a number of setting options.
On the far left (1) there is a drop-down menu that controls whether the search condition is evaluated at all during the search.
| Activated |
The search parameter will not be used. |
| Deactivated |
The search parameter will not be used. These parameters are greyed out.
|
|
Default setting |
The search parameter will be used depending on the part type and the Plant Engineering settings for search parameters. |
The next column (2) contains the automatically preset search condition. If you click on a position in the drawing, the entries will be filled accordingly to include the part type at this position.
The next column (3) contains an arrow. This indicates whether the automatically generated 
search condition or the one specify by you 
is used.
The column next to the arrow (4) contains the search condition you have specified. Any condition that corresponds to the Plant Engineering search syntax can be entered here.
Column (5) contains a button 
with which you can pick up a search condition from the drawing. The following buttons are also available for pipe classes:
|
|
Activates the pipe class search |
|
|
Deletes the manually entered pipe classes |
Various search attributes are arranged in groups, such as connection types. In this case, you can click to expand the whole group and set it according to your requirements.
There are three buttons under the search conditions.
|
|
Reset user inputs Reset the search conditions you entered. |
|
|
Select reference part Picking a part in the drawing to fit it again. This corresponds to the option Part from reference part in the old part insertion. |
|
|
Select reference part depending on part type Allows you to filter the selection by the active part type. This button is only available if a part type is selected at the top of the dialogue. In contrast to the usual selection of a reference part, only a part with the selected part type can be selected.
This selection mode is intended for parts that are difficult to select without narrowing the part type. For example, a gasket may be completely hidden by a fastener. Through the filtered selection, though, it can still be selected. |
|
|
Select part
Search for a part. The specified conditions are used and HELiOS or the catalogue is searched for a part to be inserted. If a part has been selected successfully, the part type and the part name are written into the Selected part area. |
As soon as a valid part has been selected for insertion, a new tab appears at the top of the dialogue, in this case Part insertion: Standard. While in this tab, a click in the drawing no longer means that the search conditions are modified, but that the part is inserted.
When placing the part, a preview is displayed. A red preview means that the selected place is not suitable for inserting the part.
On the Part insertion tab, there is also more information about the part that is being inserted.
During insertion, an attempt is made to automatically connect a part with the most suitable connection. For example, when connecting a flange to a fitting with a flange connection, the part is automatically rotated so that the flange connections meet. The context menu also contains other settings that can be used to control the insertion, some of which also have shortcuts:
|
|
|
Shortcut |
|---|---|---|
|
AutoConnection |
This automatically tries to determine the best possible connection. |
0 |
|
Point n on cursor |
This switches off the AutoConnection mechanism and inserts the part with the default connection. |
1 - 9, depending on part / connection |
|
Reverse orientation |
This controls the direction in which a part is placed on a guideline. |
|
|
Switch axis |
Some parts have "axes" along which they can be placed on guidelines. For example, if you select a cross and have point 5 at the cursor, either the axis from 1 to 2 or the axis from 3 to 4 can be placed on a guideline. This option allows you to change this axis. |
In addition, the TAB or SHIFT+TAB key can be used to change to the next or previous connecting point.
A special feature is the insertion of straight pipes. Here, the start and end points must be selected, between which the pipe can be routed. In the meantime, a preview of the pipe route is shown.
When installing straight pipes, there are also options in the context menu to occupy a single edge or an entire guideline as far as possible:
Please note:
-
If you move the cursor over a guideline, the flow direction is shown. The flow direction arrows are always shown on the guideline over which the mouse has been moved.
- It is normally not allowed to place a pipe clamp freely in space. An exception is when the pipe clamp is installed as a sub-part of a fixed superordinate part. In this case the pipe clamp is not part of a pipeline, so the free placement does not create an invalid pipeline structure.
Settings
At the bottom of the dialogue there are various settings on the tabs General and Straight pipes:
General
| Immediately insert part after selection |
If you select a place where the part can be placed unambiguously (e.g. a guideline corner or a part connection), the part can be inserted immediately after the search. This option controls whether this happens. If a part is successfully inserted after the selection, there is no automatic switch to the Part insertion tab. However, you can still insert the part several times by switching manually. |
| Rotate part after insertion |
Controls whether the part rotation dialogue should be displayed after insertion of a part. |
| AutoFlange |
If this option is active, flanges are connected to all flange connections of the inserted part. |
| AutoReduce |
If this option is active, a check is made at all connections of the part after installation whether the nominal width matches the nominal width of the pipe or the guideline. If not, an attempt is made to install a corresponding reducer. |
| Fix superordinate part |
This option is only intended for vessel construction and replaces the plant construction settings Insert part as main part/sub-part. When building a vessel, it allows you to select a part under which the new part will be inserted. With this option, no piping can be selected. Also, a warning is displayed if this option is active, as it is really only for container construction and otherwise you will quickly get errors in the body structure.

Straight pipes
The fields for inserting straight pipes correspond to those on the Straight pipe tab in the Plant Engineering settings.
Favourites
At the bottom left of the dialogue there is also a button to save Favourites 
. All settings as well as values entered by the user are saved and can be reloaded at any time. In this way, a configuration can be compiled for certain subclasses, which will be used again and again in the search.
The Show all checkbox under the search criteria is also provided for this purpose. The search attributes are hidden depending on the currently selected subclass. By activating the checkbox, all can be shown in order to be able to fill in all fields when creating the favourites.
You can find out more about managing favourites here.
