Project: HiCAD P+ID
In contrast to other types of connection, each section of the connection line is linked to a Pipe part symbol that is not visible in the drawing for pipe connections. This symbol can, in the same way as other pipe part symbols, be assigned to a pipeline symbol. You can edit it in the same way as other symbols; select the appropriate section of the connection with the cross-hairs. The associated edit mask appears on your screen. The symbol is automatically deleted if the section is deleted.
You can choose between two pre-defined line types for pipe connections. The icon for Type1 supplies connection lines with Line type 1, while the icon for Type 2 supplies connection lines with Line type 2. Please refer to the Settings chapter for information about pre-setting line type parameters for line types.
If a connection line starts or ends on a symbol connection that is already assigned to a pipeline, then the pipe part symbol belonging to the connection line (pipe section symbol), is automatically assigned to the same pipeline symbol.
If you attempt to link two symbols that are assigned to different pipelines, an error message is output. HiCAD also rejects the connection of parts with different nominal diameters. If none of the symbols at the end of a connection line are assigned to a pipeline, HiCAD issues the message:
Creating a new pipeline.
In case of a designation according to DIN, you are expected to position the code text for the pipeline with the cross-hairs. HiCAD then displays a mask enabling you to enter the pipeline number.
In case of a designation according to KKS, you are expected to position the pipeline tag with the cross-hairs. The tag should be positioned, with the help of the intersection point of the cross-hairs, on the new pipe connection or a section of the connection line; this ensures that the tag is automatically aligned in the direction of flow. When the tag has been positioned, a mask enabling you to enter the aggregate designation is displayed. If entries for Plant code and Plant unit are empty or incorrect, they should now be updated.
You can now determine the flow-direction for the connection line. HiCAD first suggests the direction in which the connection line should be drawn. If you do not agree, respond with YES to the question whether you would like to change the direction. If you respond with YES, the possible options are displayed in sequence, if you select NO , the suggested direction will be applied.
