Go to your Manage Tab.
Manage Panel > Manage Links.
click on the (current) Linked file.
in the lower left of that dialog box, you'll see the button "Reload From..."
Choose the new consultant file.

When reloading, you'll get a message about the need for Coordination Review.
HTH

Check the option if Reuse matching levels and grids is checked. You will not have duplicated element.
This option is not available for Wall and Floors but it's automatic.
In all case, resolve all coordination warning before reloading the linked file.

I am running into another problem. I have linked the revit model from the arch, but after if finishes loading, the only thing that shows is the grids. No messages pop up indicating any thing is wrong. i have checked the vg and i can't to seem to find anything wrong unless I am missing something.

Any ideas

Go to a section or elevation and make sure that their first floor level is at your first floor level, if it's not then move it so that it is. Also, you could go to the VG and set it to "by linked view" or discipline to "architectural" and possible see everything that you would need to.

okay i am still having problems with this copy/monitor thing. so what i have done is that I have removed all revit links from my model and started over.

I have done the following

gone to insert, select "link revit", selected the revit model i wanted and position of "auto-origin to origin"

went to VG, selected the revit links tab, under the display settings, selected "by host View". on the basics tab, selected "by linked view" button. Had to reselect my current level which the ground floor. hit apply, then ok twice to get back to my model. (changed the revit link to half tone. The arch ground floor shows up but the other floors do not.

is there a way to change so that all floors are shown. I checked an elevation, all levels line up.

not sure what I did wrong. where do i set the discipline to "architectural". if i set the displine in the properties of my model, that changes the view of my model on my end.

I'm trying to follow what you've done in order to help you.

When you inserted the revit link, origin-to-origin, were you in a plan view or a section or elevation view? (I typically do insert my links in plan view. And, as you, auto-origin to origin.)

Same question when you talk about going into VG... plan view or section or elevation view? It sounds like you actually told Revit to only show the ground floor of the linked model. If you were in a section or elevation view when you did the VG items, because you picked "ground floor" that's all you're going to see.

In VV, I typically set my linked models to Halftone, Underlay and Custom. Rarely, expecially in cases where I'm trying to coordinate something I just cannot see otherwise, I'll change items on my Basics tab. Otherwise, I leave the Basics tab alone and skip to my Annotation Categories tab.

... The title of this post is about Copy/Monitor, so, after I've copy/monitored my grids and levels, I do the following: In my Annotation Categories tab, I change the Annotation Categories: to <Custom> and uncheck the box for "Show annotation categories in this view." I do this because I do not want double (or triple, or more depending on how many models I have linked) grid bubbles or level indicators.

After I've turned off the linked annotations, I go to my Model Categories Tab; I also change the Model categories: to <Custom> and choose ~just~ the items I'm interested in seeing from my linked model. Make sure the box at the bottom is checked, "Show categories from all disciplines" to make sure you can turn on/off items you desire. For your coordination in getting the linked model to line up in the right place, you may want to see floors; however, if you're going to have your own floors in your structural model, you'll probably want to turn off the linked floors later. (In the pic below, all I wanted to see were the walls, curtain panels/systems and windows (though the walls and windows were down further in the list.))

This procedure is view specific. Each view can have different items showing as you wish. Next up for you is Filters and View Templates!
