2 Got Your Attention? Good!

3 The Wire Frame Model 1. Open the existing file: C:\RTCAUS2011\20-Massing for Revit MEP\01 Massing for Revit MEP.rvt 2. Open the Level 1 floor plan and from the Insert tab, select Link CAD. 3. Browse to the folder C:\RTCAUS2011\20-Massing for Revit MEP and select FloorPlan-Level1.dwg. Before linking the drawing, ensure that the settings for importing are as follows Current view only set to OFF; Colors: Black and White; Layers: All; Import Units: Autodetect; Positioning: Auto-Origin to Origin; and Place at: Level 1.

4 The Wire Frame Model 4. Next, create building grids From the Architect tab, select the Grid tool. Using the pick tool, start with Grid A and select each subsequent grid except for the intermediate grids. You can come back and do those after creating Grid J. Once the vertical grids are complete, do the horizontal ones. Starting at 1, you will rename this first numerical grid and then follow on with 2, 3, and so on. Once all the major grids are created, go back and create the intermediate ones. This workflow means you only have to rename a few grids rather than every single one.

5 5. With the Grids complete open the North Elevation. 6. Import Elevation-NORTH.dwg. For this import and the other Elevations, use the Auto Center - Center option. Using the 3D grips, stretch the grids to a suitable height and then align the linked dwg grids to the ones created in this project file. Repeat for South, East and West (Note: you will only have to adjust grids in either East or West views as long as you have used the 3D option)

6 7. Create new Levels for Level 2, 3 and Roof The new levels may not come in with the correct names, so you will need to edit them. When editing level names, Revit will prompt you with the message as shown It is important to click on Yes. At this point, we are trying to create a set of default views that match the Architecture.

7 As you create the levels, the corresponding views will have also been created. Open Level 2 from the Project Browser, and check the location of the imported Elevation drawing. It is possible that it does not lie on the correct plane. If this is the case, use the align tool to reposition the drawing to the correct location. Do this for all elevations.

8 9. Create floor plan views for Level 3 and the Roof. Repeat the steps to import the Floor Plans FloorPlan- Level2.dwg, FloorPlan-Level3.dwg and FloorPlan- Roof.dwg Also the Elevations Elevation-SOUTH.dwg, Elevation- EAST.dwg, and Elevation-WEST.dwg. Once complete, open a 3D view, your model should look similar to the image

9 10. In the Project Browser, select the newly-created plan views. This can be done by holding down the Ctrl key. With these views selected, right mouse click and apply the view the view template Architectural Plan 11. Adjust the visibility graphics In each of the Plan and Elevation views, so that only the relevant imported data is shown. Take the time to turn off layers inside the import so that you can control the visibility of levels and grids

10 Disclaimer I dislike in-place families! Massing is ONE of those places where rules can be relaxed a tiny bit! 1. Open the file 02 Architecture Wireframe.rvt Open the floor plan: Level Click the Architect tab Select the In-place Mass tool. You may get the dialog box saying Revit has enabled the Show Mass mode. This is due to the fact that masses do not display naturally in Revit and the Mass category is turned off by default.

11 3. Give the Mass a suitable name From the draw panel select a suitable line tool and trace over the building outline. At this point the tracing does not have to be 100% accurate, you can come back to this later to make it more suitable. 4. When you have completed a closed path Open a 3D view and select the completed path 5. From the ribbon, select the Create Form button If the created form is too tall, use the grips to stretch to the correct height

12 6. Click on the green Finish Mass check button. 7. For clarity The linked files can now be turned off in the 3D view. Select the Mass object and from the modify tab, select the Mass Floors button. From the dialog, place a check mark in the floors you want to create a floor.

13 8. Now create a Mass Floor Schedule. At this point you have an accurate total for floor areas for the entire building, and as yet, no building elements have been created.

14 9. Using the Model by Face panel on the Architect s tab Create floors, roofs and external walls. For large window openings use the curtain wall tool in conjunction with the cut geometry tool. This hosts the curtain wall within a host wall, effectively creating windows without having to resort to window families which could take time and effort. 10. The more you populate this model, the more data can be derived from it. Starting from the In-place mass gives you the added benefit of having an airtight model which is necessary in creating spaces that will work for all stages of your analysis, it is up to you how much detail you go into.

15 From the Level one floor plan Select the wall tool from the Architect tab. On the options bar, make sure the height is the next level above. Then trace off all the internal walls. Repeat for levels 2 and 3

16 The next step is to create the rooms. 1. From the view menu, select: Schedules > Schedules and quantities, and create a new Room Schedule. Although rooms have not yet been defined, we can quickly populate a room schedule with all the necessary rooms for the project. Select the following fields for the schedule: Level Number Name Area and Volume

17 2. In the Sorting / Grouping tab Apply the following sorting conditions: 3. Finally from the Formatting tab Make sure that the field Level is a Hidden field ( Area and Volume calculate totals ( ) ) and that both 4. You now have a schedule that is completely blank

18 5. Create new rows in this schedule For the number of rooms in the project. You can see from the following image that the rooms show up as not placed that is the next stage.

19 6. Open the file 05 Architecture Internal.rvt This has all the room name and numbers defined, all we need to do with this file is to place the rooms simple, I hear you say, but not so fast 7. Open the Level 1 floor plan Select the Room tool from the Architect tab 8. With the command active You need to pay close attention to the options bar, you will need to select: Upper Limit - For Level 1, this will be Level 2 Offset - Set this to Zero Room - Select each room that has been predefined

20 9. Populate all levels with the rooms. The following message is an indicator that there are two rooms trying to occupy the same space, this can be where the architect is defining different areas for differing work purposes. Do not delete the room, use the Room Separation Line tool. This allows you to have different areas / rooms without the need for actual walls.

21 1. Open the file 07 Services Project - START.rvt Double click on the Level 1 floor plan. 2. Link the Revit project file 06 Architecture Rooms.rvt Using the Origin to Origin option. 3. Open the North elevation From Collaborate tab, select the Copy/Monitor tool. Use the Select Link option and select levels 2, 3 and Roof. Also select Level 1, but only choose to monitor this level. 4. From the View Menu Create floor plans for Levels 2, 3 and Roof 5. With the floor plans are created From the Analyze tab, select the space tool.

22 6. Before selecting Place Spaces Automatically Make sure the Upper Limit is set to Level 2 with an offset of zero. This will create 24 new spaces on level Repeat for Level 2 and Level 3.

23 8. Now we can use the Space Naming utility. This tool is supplied free of charge to subscription customers, and will update all Space names to match those of the corresponding room names in the Architectural model. 9. We are almost done! One of the final checks is to look at the Heating and Cooling loads dialog Check whether there are any warning triangles associated with any of the spaces.

24 10. We can also look further into the individual spaces Using the isolate tool, and look at the Analytical Surfaces. This is where the extra work we did earlier really pays off. Any windows created actually show up as openings in the analytical model. 11. Perfect for export To gbxml and importing into analysis programs

25 12. Also perfect for standard documentation. In each plan view you can override the view properties so only the 2D plan is shown from the architecture, while the Revit MEP model objects are also shown. The distance the shot-put goes depends upon the effort put into it!
