Link a Document to a Database Element

To add a link between an element and a document (or an external resource):

1. Create a new Link Descriptor somewhere in the links hierarchy.

2. Set its URL to the desired internal or external reference.

3. Link it to a database element using a DLADD command.

You can also link a document to an element using an existing Link Descriptor, because many database element can be linked to the same document:

4. Locate a LNDESC in the links hierarchy.

5. Link it to a database element using a DLADD command.

The DLADD command can be used to add links from a document to one or more other elements. The command syntax is:

----------------+

/ |

>--- DLADD -------*-- <selatt> -----+------>

It is possible to create an association both by adding a link from a Link Descriptor to a database element and by adding a link from a database element to a Link Descriptor. Examples are given below.

If current element is a Hull Panel Element (HPAN) named /PANEL1 the following command assigns Link Descriptors /MYDOC1 and /MYDOC2 to /PANEL1:

> DLADD /MYDOC1 /MYDOC2

If current element is a Link Descriptor (LNDESC) named /MYDOC1 the following command assigns this Link Descriptor to /PANEL1 and /PUMP1:

> DLADD /PANEL1 /PUMP1

The whole process of linking a document to /PUMP1 might look like this:

> NEW LNDESC /MYDOC

> URL 'http://aveva.com/all_about_vm12_link_documents.pdf'

> DLADD /PUMP1
