One of my modellers got themselves tripped up yesterday when they couldn’t get their ceiling tiles to appear in a reflected ceiling plan view no matter how much they adjusted their view range and other visibility settings.

The problem was simple, it was the underlay orientation; but the option to change it was greyed out and the modeller was stumped, they had an RCP view but they were stuck with it displaying as a floor plan.

The problem was the discipline setting of the view – it was set to coordinaton rather than electrical. When you have your view set to coordination or architectural in the discipline option, the underlay setting is not able to be changed.

As long as the ceiling tiles have been modelled in the linked architectural file as soon as you change the underlay orientation to reflected ceiling plan, your ceiling tiles will appear.

Of course this doesn’t just apply to electrical, it applies to mechanical, fire and hydraulics services as well.
