Revit and shared coordinates


I have been working n a project with a number of buildings. To begin with I had them all in one model, but as the scheme developed the buildings became a bit more complex, the forms settled down, and I decided to split them into seperate files to manage them better.

Revit shared coordinates

I’d developed their form, bulk and location on the site plan, so next phase was to develop the individual buildings, which is easier to do as stand alone files, they are specific to the job in hand and the files are smaller, hence faster to load and move around in.

I have not done too much stuff in the past with linked files so I found that i was faffing around with the Project Base Point & the Shared Coordinate point, just sort of pushing them around a bit. I found I was not that successful with locating the seperate plans in relation to each other. I was cutting Lat/longs from one model’s shared coordinateds into another model, but on linking it didn’t recognise them as Shared coordinates.

Another issue I was having was levels in links, I was bringing them through but only getting a partil bit of the link. On examining it in 3D I would find that the model was floating up in the air, so the levels were not aligned, and had to modify the links elevation to get it to come in correctly.

Then I found the following video on YouTube that shows its quite a simple perocess when you know what to do.

To make the Project Base Point & Shared Coordinate symbols appear you have to go to the Site category and turn them on. Its a weird place to have them located, makes a type of sense, but not intuitive in my opinion.

Linked plans and working on models in the links.

Thers is always the issue that you are in the site plan and see something in a linked model that needs a correction of some type. If you have the site plan open you have to unload the link before you can open the model in the same revit instance.

The better way to do it is to open a second instance of Revit (Hold down SHIFT and click on Toolbar Icon) and a second instance of the programme will start. You can then update the linked model, save it, then go back to first instance of Revit and re-load the link into the site plan.

This is all well and good until you want to copy/paste something between 2 models, say you’ve drawn some pipes external to building onto site plan but then decided that you need it in the actual building? In this situation you have to open up both the models in the same instance for the copy/paste to work. The copy/paste will not work between 2 seperate instances of Revit.

Update Saturday 19th Oct. Revit Pure brought out a document on the subject:

Pamphlet #14 is here! This issue is about shared sites and the shared coordinate system in Revit

MEP connectors

I haven’t done too much work with MEP stuff, and what I did do was a while back. I do not recollect using the connectors item that I found out about in the Balkan architect’s video below. I thik he is pretty good at what he does and I like his videos as he explains things quite well.

When looking up the info for connectos i came across the one below for MEP equipment and I think this video is pretty good for when you build MEP families. I’ve linked it here for reference for the future.

Floors & walls tips and tricks

I also watched a couple of the Balkan Architects tipsd for floors and walls. I didn’t know a lot of the floor ones,so its a handy reference.

The wall ones I’m pretty comfortable with apart from the hidden line. I like that so will keep the vid below for reference

These are just a good reference point to go to for a couple of things I may want to try. The site shared coordinates is definitely a handy one.
