Controlling Joist Visibility in Structural DocumentationCenter TN

Joist Visibility\Dataset Assignment

If joists do not show up in your plan views it is because they are assigned a dataset Family=Steel Bar Joist and Part=Members. The drawing rule in the model Part=Envelope. The dataset assignment in the Analysis Import dialog box needs to match the drawing rule.

Here is the drawing rule that is being used for Framing Plans. The left column is the dataset assignment….the Drawing Definition rule in the model is set up to resymbolize “Steel Bar Joists: Envelope”. Any members that do not match one of these criteria will not be shown. So, the joists in the model are being skipped because Part=Members does not match the drawing rule Part=Envelope. Even though the Family=Steel Bar Joist is the same.

The Bar Joist tool in Bentley Structural creates an envelope in addition to detailed members. The various components normally have different dataset assignments.

In the case of RAM Structural System we bring in only the “Envelope” – no detailed members – so that is why the drawing rule is tied to an Envelope part. See the drawing rule definition below.

You can use the Information tool to see the dataset assignment. Here is a joist set to Members instead of Envelope:
