Tagging Rooms all at once

When you use a model in your MEP drawing from an Architectural link, chances are there are room names associated with it. And we really do want to see those room names in our model too.

So, it took me a bit of playing around to figure this out (remember, I am a Revit newbie). At first, I saw the Room Tag (RT for typers) tool in the Annotate tab.

This is fine, but it only does one room at a time. We could do that, but we are trying to be productive. So how does one get all the room names in on a view at one time? The secret involves the tool called Tag All. Actually, if you hover over the tool name, you get a better feel for what this tool actually does (Tag All Not Tagged).


So, by bringing up the Tag All tool, you get a dialog which might look confusing at first. Three are a slew of categories (based on what is in your model, how you set your template up, etc.) and their associated tags.

We are interested in this post for room tags. Drill down through the list until you see the Room Tags category. In our example, we have two different room tags available. We only want the room name to appear, so we’ll choose just the room Tag loaded tag.

There are some options for creating these room tags, such as creating a leader and orientation. There is one very important item we need to check here before proceeding. The check box that says ‘Include elements from linked files’ must be checked. We are grabbing the room names from our linked Architectural model.

Click OK, annnnnnnnnnnd………… nothing happens! πŸ™‚

Alright, I lead you on. There is one important step you must do. In order for this to work, you must have the crop region visible. Toggle the Crop region so that it is on and then try the Tag All toolΒ  again.

Ahhh, much better! With the Tag all tool, we have only performed a small portion of what this tool can do to help simplify and streamline annotation for you. Hope this tidbit helped.





Revit commands – ALIGN

I’m going to start posting some of my favorite (and least favorite) Revit MEP commands and tools that either AutoCAD doesn’t have or has but is different. This installment is on the Revit MEP ALIGN command.

In the example above, I have 2 rectangular ducts that I wish to put them on the same plane or elevation. You can find the Align tool in the Modify tab, or simply type AL (remember, no return key here).

The first prompt is: Please select line or point reference for alignment. This is simply asking you to select the first object that the second will be aligned to.

The next prompt is: Please select an entity to align (it will move into alignment with the reference). Can’t explain that one any clearer. πŸ˜‰That’s basically it! Type AL, 2 clicks – done! Well, almost. Looks CAN be deceiving. Lets cut a section and see what the problem is:

You can see that while the ducts are lined up in one view, they are not in another. If you were to join those two ducts together in that view, you would end up with some weird transition, or perhaps it wouldn’t allow the connection at all. These are things to keep any eye out for when you are aligning.

to fix this, just run the ALign command again on the other view. Note that aligning rectangular ducts or equipment, you can (most of the time) align using the edges of the duct or equipment. When working with round duct or pipes, the connection point will always be to the center. A wishlist for me would be that there would be an option to allow it to align in all views to the same planes.

The AutoCAD equivalent for doing the same things is the move with osnap set to near or endpoint. You CAN use the Revit Move command, but this just seems to work better, in my opinion. And the AutoCAD Align command really has nothing in common with the Revit Align command – go figure.Β  See you next time with

New Project Setup – our way

I am writing this blog entry more as a step-by-step tutorial for myself. The methods here may not match your company standards, so caveat emptor. This is in response to my recent ‘baptism by fire’ into project setup. My first one took what I thought was an extraordinary amount of time to set everything up and I needed make sure that I documented the steps somewhere, so this it. I will list the step-by-step instructions on how WE set up a new project. You can follow along if you like πŸ˜‰

Architectural Revit Model

It all starts here. We base our project sheet layout basically like the architect as they are the ones we need to please in order to get more work. They (and I agree) like to see consistency throughout the finished project sheets.

  1. Open the Architectural model from the received folder. Ensure that the Worksharing ‘Detach from Central’ is CHECKED.
  2. Print all the Architectural Sheets for later use.
  3. From the Manage tab, click the Manage Links tool. Click through the tabs and delete any entries. Click OK
  4. Still in the Manage tab, click the Purge Unused tool. Click OK.
  5. From the Revit ‘R’, click SaveAs > Project. Navigate to the 01_CADD\BIM\Models folder. The naming convention we use is: ProjNo_v12_ArchName_Mech. the v12 shows that the project is in Revit MEP version12. Replace the existing model if prompted to do so.
  6. Close the Architectural model.

The Architectural Model is now ready to be used. Note: The above steps also apply for when the Architect updates their Revit Model. This will also apply to other disciplines (Structural, Electrical).

New Project Creation – Linked

Now we will take the newly imported model and use it in our new project.

  1. From the Revit ‘R’, click New > Project.
  2. In the New Project Dialog, make sure the Template file is pointing to the correct place (It should be set as default). Click OK
  3. From the Insert tab, click Link Revit. Navigate to the newly created Architectural model as we did above.
  4. Ensure the positioning is set to ‘Auto – Origin to Origin’ and click the Open button.

The architectural drawing is now linked into your new project.

New Project Creation – Copy/Monitor

We want to create a section so that we can Copy/Monitor the Architectural levels.

  1. Open a typical Architectural Elevation. If there is none, go ahead and create a section through the architectural building so you can see the established levels.
  2. From the Collaborate tab, select the down arrow next to Copy/Monitor and select ‘Select Link’.
  3. Pick an Architectural level to activate the tool.
  4. From the Copy/Monitor contextual tab, select Copy, and then select the Multiple check box.
  5. CTRL-Click the Levels you wish to Copy/Monitor. Then click the SMALL finish button (next to the Multiple check box).
  6. Re-select the Copy/Monitor contextual tab (this seems redundant, but I guess that’s how Revit MEP works), and click the Finish tool (the one with the green check mark)

You have now Copy/Monitored the linked Architectural sections. The advantage of this step is that if the Architect happens to make a change in elevations, it will automatically be reflected on our MEP drawings when we get the updated model.

New Project Creation – Cleanup/Creation

This is (in my opinion), the most tedious part of this whole process. We are going to drill through the linked Architectural model and get rid of things that we, as MEP don’t care to see; things such as their notes, symbols, legend, sections, etc. we the are setting up views to match the Architectural plans (remember, entire project consistency is the key here).

  1. We have to have at least one Architectural floor plan, so don’t get too delete-happy. πŸ˜‰
  2. Delete all sections, elevations, schedules, notes, legends.
  3. Delete all but ONE sheet. We will need the title block for later steps.
  4. Open the Architectural Level 1 Floor Plan.
  5. Right-click on the name in the Project Browser and apply the view template. In this case, It will become a Level 1 Mechanical Plan (HVAC, Mechanical Piping). Compare the scale to that of the Architectural and adjust accordingly.
  6. Enable the Show Crop Region and adjust the region so that it is similar to the architectural plans (the ones that we printed out earlier).
  7. Hide the crop region.
  8. Repeat steps 4 – 7 for all other plans that you anticipate you will need (such as Demolition, Plumbing, Fire Protection, etc.). Set the view template accordingly too.

Sheet Setup

Now, we are going to set up our sheets (what will be printed). Here , it is very important (for our firm) to have the plan sheets, no matter if they are Architectural, Electrical – what have you; all look the same – that is, the same plan view show in the similar location on the sheets.

  1. Open up the Architectural Sheet family. We need to add our logo to the sheet and make it a Mechanical sheet.
  2. Navigate to the location where the logo is and drag the family onto the architectural sheet family.
  3. Load the Architectural sheet family back into the project, overwriting any settings (we want our logo to be a “permanent” part of the sheet. It may prompt you where to save the project if you have multiple projects open.
  4. Back to our sheet that was brought in via the template, We will bring in all the information that the Architect has set up on the sheet; such as Name, Address, etc. On the Manage tab, select the ‘Transfer Project Standards’ tool.
  5. In the Select Items To Copy dialog, click the Check None button. this clears all of the entries. We are only interested in a few of them.
  6. Click the Phase settings, Project Info, Viewport Types check boxes and click OK.
  7. From the Plans created on the Project Browser, click on the corresponding Plan and drag it into the sheet. Line up similar to the way Architectural has their sheet set up.
  8. Repeat for all other sheets.

That is basically how we set up our new projects. As I mentioned from the beginning, you methodology/standards may vary. If you suggestions that might streamline the process, or any comments in general, I welcome them. If you’ve made it this far in reading, I thank you. πŸ™‚
