Hi,
At the moment it is not possible to display hidden lines in an Ortho view that has been generated from a plant model.
A feature enhancement request has been logged with our development team for this functionality to be included.
Thanks,
Dan
This is an important feature required. Hope this will be a part of release in Plant2014
Hidden lines are available in the 2014 version, but you do not get to pick which hidden lines you would like to show. The settings are show all hidden lines or none of them. If you turn on the hidden lines feature, you'll be overwelmed with the detail. For an example, for every orifice flange, the pipe bore and side tappings will show up.
I generally just draw in the ones I need at the moment.
