Creating a Mass

00:02

 I really like massing in Revit, when it works, that is.

00:07

Just like anything else, you need to know its nuances and its quirks.

00:12

Sometimes, something that seems quite simple, Revit will struggle with.

00:17

Other times, Revit can do amazing things in massing.

00:21

The objective of this video is to do something in between the simple and amazing.

00:26

By using the reference planes, we can now sketch the basic form of our mask.

00:33

which will become a roof.

00:35

So let's jump into Revit. To open the model, I could browse out through the open dialog box.

00:45

Or, since it's been recently used, it is here in my recent files.

00:50

I click on the recent files.

00:53

This is a central model. And it needs to create a local copy of it, which is fine.

00:60

And I want to override my existing local copy to ensure that I have all the latest information from the central model.

01:11

I double click on my garden floor plan to make it active.

01:17

And this section that we generated last session actually has a pretty bad name, Section 1.

01:27

I double click it to activate it. And in my properties, I can rename it to a much more descriptive name.

01:36

I will call it Garden Roof Section.

01:41

Now what I want to do is I want to create a few more reference planes to complete the grid.

01:47

This previous reference plane that I generated is a little bit too short.

01:53

So I'm just going to click on it and drag it out with the grip like I'd done earlier.

01:59

And now I want to create another reference plane like that. So in my Quick Access bar I can click on Create Similar.

02:07

I don't want to draw another reference plane.

02:10

I want to pick an existing reference plane and offset it.

02:14

So I click on Pick Lines.

02:16

Set my offset value to 8 feet.

02:21

And as I hover over the reference plane, you'll see this blue dashed line as to which side is going to be offset from.

02:28

I'm going to offset it on the inside, and come over to the other reference plane that I generated, and offset that on the inside as well.

02:40

I click Modify to finish my command. And in my measure panel, I click Align Dimensions, which is also available in my Quick Access bar.

02:51

I want to generate a dimension line from these four reference planes.

02:55

So I just go and touch the four reference planes.

02:58

And then I tell it where I want the dimension to be located.

03:03

So I just click above the atrium roof.

03:07

And now you notice that I have this EQ with a line through it.

03:12

I click on the EQ, which will make these dimensions all equal, so the reference planes are equally spaced apart.

03:23

Pretty cool.

03:24

I click on Modify, and we're just about ready to start creating our mass.

03:31

However, before I do that, I want to generate a customized 3D view.

03:36

So I click on this existing roof.

03:40

And I can go to my section box in my Quick Access bar.

03:44

I hit Escape and ZE for zoom extents. Now I want to increase the size of this section box.

03:53

So I click on the section box.

03:55

And you notice along all four sides there are some controls that allow me to enlarge it or shrink it.

04:06

So I'm going to enlarge the four sides. This one's a bit hard to see.

04:12

And there's also one on top, so I'm going to increase the height of my section box.

04:19

Click on Modify, or hit Escape a couple times.

04:23

And now, as I did previously with the section, I want to rename this to a more informative name.

04:31

Now I don't need these other views open, so I'm just going to hover over Startup, and click on Close, hover Garden Floor Plan,

04:40

and close that, and WT will tile our windows, and ZA, or Z A,

04:50

will do a zoom all of all the windows.

04:53

So, great, we're set now.

04:55

So I have a nice grid over here, and I can see what's going on in my 3D view.

05:04

We actually need one more reference plane.

05:06

In the Garden Roof section, zoom in to the Atrium Roof level.

05:14

RP is for creating reference planes.

05:18

The subcategory is already set to Garden Roof.

05:22

So I'm going to pick an existing line and offset it 4 feet.

05:30

And I'm going to select the atrium roof line and ensure that it goes above the atrium roof line.

05:39

Pretty close to my crop box. It's a modify key.

05:44

Select the crop region and extend it up a bit.

05:52

Now let's click on these four existing reference planes that we generated earlier.

05:58

And just elongate them so that they intersect the newly created reference plane so we have some nice intersections to work with.

06:10

Okay, now it's time to generate our roof mass. Click Modify to deselect everything.

06:18

And on the massing site, click on In-place Mass.

06:25

We are informed that Revit has enabled the Show Mass mode so that the newly created mass will be visible.

06:33

What this means is that Revit has temporarily overridden the visibility graphics by enabling the Mass mode.

06:44

I accept that by clicking Close. And we call the mass Garden Roof.

06:52

On the Create tab, under the Draw panel,

06:55

click on SP blind through points we need to tell Revit which work plane to work on.

07:03

So we click on the name and on the dropdown list we see the six reference planes that we generated earlier.

07:11

Garden-01 to,to Garden-06.

07:15

We're gonna start off with Garden-01 and work our way back.

07:19

So I select Garden-01, click OK.

07:23

And now for the spline, for the odd ones, 1,

07:34

So I just select these four intersections that we generated.

07:42

And hit Escape.

07:44

Hit Escape.

07:49

We want to generate another spline, but we want to tell Revit that we are working in another plane.

07:56

So in my drop down list, I select Garden02.

08:00

And now I go the opposite direction, so from the top down.

08:11

Hit Escape a couple times.

08:14

And you can see in the 3D view how it's being generated.

08:22

I can hold the shift key down and orbit around.

08:25

And we see that, indeed, they are in different planes.

08:32

Going back to my Garden Roof Section view.

08:36

Now, rather than generating more splines like this, I can simply pick lines.

08:42

So I select pick lines.

08:45

I go to Garden-03.

08:48

And select the first one going from the bottom up. Now we see it in our 3D view.

08:55

It doesn't have the control points like the other splines do, but we don't really need them.

09:03

Go back to Pick Lines.

09:06

Select my Garden-04.

09:10

Select from the top down. It appears in my view.

09:15

Go back to Pick Lines. Garden-05. We're just about there.

09:22

Select from bottom up.

09:26

Lastly, pick lines, Garden-06, and select from the top down.

09:37

Okay, now we have our four, our six lines.

09:42

Now what we need to do is to hit Modify to deselect everything.

09:51

I'm going to select the six lines that I just generated.

09:56

Holding the control key down, I'll select them in the sequence they were drawn in.

10:06

From 01 to 06.

10:09

And in my contextual ribbon, I can create a form.

10:15

Look at that. So I can pan around.

10:21

Decent.

10:25

And I click on the green check mark in my contextual ribbon to finish my mass.

10:32

I am warned that the mass is only mesh geometry and can't be used to compute mass floors,

10:39

volumes, or surface areas.

10:42

But later on we will show you how to convert this to a object that can be used within Green Building Studios.

10:53

For now let's save the file.

Add Massing to a Model – Exercise

Now that we have our reference planes all set, we can add our massing. Yes, you can add massing without reference planes, but they just make it much more accurate.

To add massing to a model, follow these steps:

  1. Open Revit.  
  2. Open your architectural model. 
  3. Open the Section 1 view. 
  4. In Properties, rename the view to Garden Roof Section
  5. Type RF to start the Ref Plane command. 
  6. Ensure the Garden Roof subcategory is selected. 
  7. Select the Pick Lines option in the Draw panel. In the Options Bar, set the Offset to 8′-0″
  8. Pick the left vertical reference plane created earlier, and watch for a blue dashed line to indicate which side the new reference plane will be offset from, as shown below. Ensure it is being offset to the right.



  9. Use the same steps to create another reference plane, but this time offset it to the left. 
  10. On the Modify tab, click the Aligned Dimension button. 
  11. Select the four vertical reference planes, then select an area above them to place the dimension. 
  12. Note the crossed-out EQ text near the center of the dimension line. Click on it to enable the equal spacing of the reference planes.



  13. Select the roof structure and in the contextual tab, click Selection Box, as shown below.



  14. Adjust the four sides of the section box to enlarge it. 
  15. Rename the view to Garden Roof 3D
  16. Close all other views except for Garden Roof 3D and Garden Roof Section
  17. Tile the two views using the WT keyboard shortcut for Tile Windows. 
  18. Use the ZA shortcut to zoom extents the model in all open views. 
  19. In the Garden Roof Section view, create one more reference plane 4′-0″ above the Atrium Roof level by picking and offsetting from the Atrium level line. 
  20. On the Massing & Site tab, click the In-Place Mass button.



  21. Revit will enable the Show Mass mode. That is fine. Click Close
  22. In the Name dialog box, name the mass Garden Roof
  23. On the Draw panel, click the Spline Through Points button. 
  24. In the Work Plane dialog box, set the work plane to Reference Plane : Garden-01.



  25. Draw a spline similar to the one shown below.



  26. Press <Esc>. 
  27. Click the Spline Through Points button again. 
  28. In the Placement Plane drop-down list, select Garden-02, as shown below.



  29. Draw another spline on the Garden-02 reference plane. 
  30. For the splines on reference planes Garden-03 through Garden-06, use Pick Lines in the Draw panel. Your splines should look similar to those shown below.



  31. Hold down <Ctrl> and select all six splines in the sequence they were created in. 
  32. In the Form panel, click Create Form
  33. Click Finish Mass
  34. Your form should look similar to the one shown below.



    • If you get a warning that says Mass contains only mesh geometry, which can’t be used to compute Mass Floors, volume, or surface area, that’s OK. 
  35. Save the model. You are all set to apply an actual Revit surface.
