Question:

How can I find the proper syntax for Item Types related to Nodes and Conduits?

Answer:

You can find a full list of the MicroStation Syntax here. Here is a list of the most common syntax to use for Item Types on nodes and conduits:

If you want to see all properties available for inclusion in item types, then:

  1. Create a new DGN
  2. Place the elements you are interested in. Create as few elements as possible – e.g. one node, or two nodes and one link
  3. Make a note of the names of the elements created
  4. Use the key-in ecx items dump
  5. Look in the message center to see the name and location of the file created
  6. Search the file using the name of the element
  7. Review the names of the properties – you should see some that look familiar
