# Page 13 - AutoPipe - Flanges

This page allows you to setup the [AutoPipe](/plant-tools/plantspecdriven/how-to-use/concepts/autopipe.md) options of PlantSpecDriven. If you disable the [AutoPipe](/plant-tools/plantspecdriven/how-to-use/concepts/autopipe.md) checkbox, then al lthe other settings will be disabled in the user interface. This also applies to the settings on [Page 14 - AutoPipe - Fasteners](/plant-tools/plantspecdriven/how-to-use/configuration/the-wizard/spec-driven-lines-symbols/page-14-autopipe-fasteners.md).

By default, nothing is selected.

You start by selecting the property which holds the Symbol Name of your P\&ID symbols (see [Inline Assets Class](/plant-tools/plantspecdriven/how-to-use/configuration/pid-properties/inline-assets-class.md)). If you don't select the property PlantSpecDriven will not be able to substitute the symbols.

Next you select the class under which all your flanges are located. In [Test Projects](/plant-tools/plantspecdriven/how-to-use/test-projects.md) you will find the flanges under the Piping Fittings class. Select the class in the tree and use the right arrow symbol to copy the class to the right.

Next you select the flange class which is supposed top be used as the default flange symbol in case there is no spec given in a line segment and therefore PlantSpecDriven doesn't know what spec to look into (see [Flange Class](/plant-tools/plantspecdriven/how-to-use/configuration/pid-classes-symbols/flange-class.md)).

Next you select the End Types PlantSpecDriven should react on. Typically you will select FL and WF, but you may have other End Codes defined as Flange Like.

If you use [AutoPipe](/plant-tools/plantspecdriven/how-to-use/concepts/autopipe.md) also for other End Types (e.g. TriClamp) you may consider adding other End Types from the list.

![](https://2994090777-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FZH2AGHzvPfBW7YdaaGc0%2Fuploads%2Fgit-blob-c6e4cf8b38ff66e80c4a3a2c9ef769a7e3476e83%2FThe-Wizard-0049.png?alt=media)

With the settings under **When selecting flanges from Spec** you define which end type should be used to filter the spec (in addition to the size and probably PSD\_Key). If you use PlantSpecDriven for flanges only, then **FL** should be sufficient, but when using for example something like TriClamps you may have to use other end types as well.

![](https://2994090777-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FZH2AGHzvPfBW7YdaaGc0%2Fuploads%2Fgit-blob-a3a4f8576c4edfd56b482ceb3b29d22d3693ab9e%2FThe-Wizard-0075.png?alt=media)

The **Select Symbol Names** is needed only if you manually insert flanges in a line segment to generate a double flange connection.

If you don't use this in your P\&ID drawings, then you can leave this section blank (see [Flange Class](/plant-tools/plantspecdriven/how-to-use/configuration/pid-classes-symbols/flange-class.md)). For every **Manual** flange type you must select the opposing **Autopipe** flange.
