Position Penetrations

The Position menu options allows you to reposition penetration elements in the following ways:

Penetration

Allows you to move a penetration hole by a given displacement. To do so, navigate to the CMPF or CMFI to be moved and select this option; the Explicit Position form displays:

This form allows you to reposition an item which is constrained to lie within a plane (such as a panel fitting which lies within the plane of a panel loop) by moving it from its current position by a given distance in a given direction.

To move the element whose identifier appears near the top of the form:

1. Enter the required X and Y components of the required shift in the Relative X and Y text boxes (using the default or specified units).

   • Alternatively:

   • Use the Cursor options to calculate the relative offset between two existing design items and copy the X and Y components of this offset into the text boxes automatically. Select the types of item which you will use from the Cursor menu and, when prompted, pick them in a graphical view. The choices for both the From and To items are:

   • Element - The origin of a picked element will define the point.

   • Design Point - The position of a picked p-point will define the point.

   • Pline - The projection of a picked pline will be used to calculate the point.

   • Edge - The projection of a panel edge will be used to calculate the point.

   • If required, use the Lock options to fix the current coordinate along either axis.

2. Click Apply to move the element by the specified X and Y distances.

3. Use the Explorer and the CE option if you want to move another element before you Dismiss the form.

   Note:
   You will normally use this option only for a penetration hole which you have created explicitly, since other penetrations will have been positioned automatically to suit the penetrating and penetrated elements.

Link Penetration

Allows you to associate a penetration hole with a piping component which does not actually pass through it, but with which it must be aligned (for example, a hole giving access to a valve hand-wheel below a floor panel; see diagram). To do so, navigate to the CMPF or CMFI and select this option. You will switch to event-driven graphics mode and will be prompted to pick the component with which the hole is to be linked. The LREF (Link Reference) attribute of the SBFI representing the hole will be set to point to the picked item and the hole will be aligned with the component.

Align with ref.

Allows you to realign a penetrating item when you have moved the hole through which it passes. Conversely, you can realign a penetration hole with a penetrating item which you have moved. Navigate to the element to be repositioned before selecting this option. (You may also need to reorientate the element in a similar way).

Note:
Realignment is subject to the following constraints:

An ATTA can only move along the centreline of its owning branch.

A CMPF can only move within the plane of its owning panel.

A CMFI can only move along the pline defined by its Position Line attribute, although its subordinate SBFIs can be positioned anywhere (their offsets from the CMFI being controlled by their DELP attributes).
