How to build a flat roof in Revit? –

  • Display a floor plan view or a reflected ceiling plan view,
  • Click Architecture tab Build panel Roof drop-down ( Roof by Footprint).
  • On the Draw panel,select a sketch or pick tool.
  • Sketch,or pick, a closed loop for the roof,
  • Specify slope defining lines.

What is the first step in creating a roof in Revit?

Transcript – To create a roof for the project, first open the level closely associated to the roof by double-clicking it in the Project Browser. Here, the Lower Parapet level will be used. Then, on the Architecture tab of the ribbon, click the Roof tool to enter sketch mode.

  • Now you can select a tool from the Draw panel.
  • In this case, you use the Pick walls tool to draw the edges of the roof at the building entry.
  • This will be a sloped roof with an overhang.
  • On the Options bar, set an overhang value of 600 and verify Defines slope is selected.
  • Position the cursor near one of the walls at the entry.

A dashed line is shown indicating the overhang position of the roof. Press Tab to highlight the chain of walls and click to place the roof boundary. The triangle shape that displays near the lines indicates they will be a slope-defining edge of the roof.

The roof in this area is higher than the lower parapet. On the Properties palette, set the Base Level to 03 – Upper Parapet and click Finish to place the roof. To more easily create the flat roof of the building, additional walls must be visible in the view. The exterior walls of the building can be seen when an underlay is applied to the view.

On the Properties palette, set the underlay value to 01-Store Floor. This lets us see the walls from the 01 – Store Floor plan in our current view. Click Roof by footprint, and again Pick Walls is used as the drawing tool. This time on the Options bar, set the overhang value to 0 and clear the Defines slope setting.

In the Properties palette, set the Base Offset from Level parameter to -750. Now sketch the roof boundary, position the cursor near an exterior wall and press Tab to highlight the chain of walls. Click to place the sketch lines and finish the roof. Open a 3D view to see the resulting roof elements. You can see the interior walls extend through the flat roof.

To correct this, we will attach the walls to the roof. Select an interior wall and then right-click. From the contextual menu, choose Select all Instances, visible in view, to select all of the interior walls. On the contextual tab of the ribbon, select Attach and then select the flat roof.

What is the simplest roof design?

Gable Roof – A gable roof has two sloped sides and forms a triangular shape. It’s the most simple roof and one of the most common.

Pros: The pitch of gable roofs promotes water and snow runoff, and the simple design is fast and cost-efficient to build. Gable roofs match all types of architectural styles. Cons: A gable roof is not ideal for areas with high winds or hurricanes.

How do you manipulate a roof in Revit?

Modify a Roof | Revit 2018 | Autodesk Knowledge Network After creating a roof, you can change its shape or overhang, cut openings, or align ridges.

  1. Select the roof, and click Modify | Roofs tab Mode panel (Edit Footprint) or (Edit Profile).
  2. Make necessary changes. If you want to change the position of the roof, use the Properties palette to edit the Base Level and Offset properties to change the position of the reference plane. If you’re warned that the roof geometry cannot move, edit the roof sketch, and check for constraints on the sketch, such as between a level line and a sketch line of the roof.
  3. Click (Finish Edit Mode).

Use this method to resize roofs that were created by footprint or by face.

  1. In an elevation or 3D view, select the roof.
  2. Drag the shape handle, as desired.

When editing the footprint of a roof, modify properties of its boundary lines to change the roof overhang.

  1. In sketch mode, select a boundary line for the roof.
  2. On the Properties palette, enter a value for Overhang.
  3. Click (Finish Edit Mode).
  1. Select the extruded roof, and click Modify | Roofs tab Opening panel (Vertical).
  2. If the Go to View dialog displays, select the appropriate plan view in which to edit the profile. A plan view representation of the roof displays. Reference planes define the boundary of the roof.
  3. Sketch closed-loop openings. Closed-loop sketches in sketch mode
  4. Click (Finish Edit Mode). How To Create Roof In Revit Closed-loop sketches become vertical cuts in the roof

You can align roof ridges in 3D and elevation views. To align roof ridges in an elevation view, use the Align tool.

  1. In a plan view, add a reference plane:
    1. Click (Ref Plane).
      • Architecture tab Work Plane panel (Ref Plane)
      • Structure tab Work Plane panel (Ref Plane)
      • Systems tab Work Plane panel (Ref Plane)
    2. In the drawing area, sketch a reference plane that is not perpendicular to the roof ridges. Reference plane in plan view
    3. Select the reference plane, and on the Properties palette, enter a name for the plane.
  2. Open the 3D view, and click (Set).
    • Architecture tab Work Plane panel (Set)
    • Structure tab Work Plane panel (Set)
    • Systems tab Work Plane panel (Set)
  3. In the Work Plane dialog, select the reference plane name you just created, and click OK.
  4. To align roof ridges, use the Align tool. Unaligned roof ridges Aligned roof ridges

If a roof includes a slope-defining arc line or circle, it creates a conical roof. If desired, you can divide the arc or circle into segments as follows.

  1. In the drawing area, select the arc line.
  2. On the Properties palette, specify a value for Number of Full Segments. If you specify zero segments (the default), a conical roof is created.

How do you add roof trusses in Revit?

Attach a Truss to a Roof or Structural Floor | Revit | Autodesk Knowledge Network Products and versions covered Revit 2016 Help Attach a truss to a roof or structural floor to force the truss to conform its chords to that element. The following rules apply to attached trusses.

  • Chord locations are dependent on their attachments and bearing chord assignments.
    • If the top chord of a truss is attached, its location line is the bottom face of the element to which it is attached.
    • If the bottom chord of a truss is attached, its location line is the top face of the element to which it is attached.
    • If only the non-bearing chord is attached, the bearing chord location will be the current location line of the unattached chord.
    • If only the bearing chord is attached, the non-bearing chord location will be the truss location line offset by the Truss Height property. The offset represents a positive distance for top chords and a negative distance for bottom chords.
  • The location line of the truss chord must be below (when attaching the top chord) or above (when attaching the bottom chord) the roof or structural floor.
  • The top chord must always have a higher elevation than the bottom chord. They may meet, but never cross.
  • The width of the roof or structural floor must equal or exceed the width of the truss. Trusses cannot be attached to structural floors or roofs that do not completely cover them.

To attach a truss

  1. Verify that roof and structural floor visibility is turned on in the current view.
  2. Select one or more trusses to attach. How To Create Roof In Revit
  3. Click Modify | Structural Trusses tab Modify Truss panel (Attach Top/Bottom).
  4. On the Options Bar, select Attach Trusses: Top or Bottom for the appropriate truss chord being attached.
  5. Select the roof or structural floor.

Note: Not all truss families properly attach to a roof or structural floor. For the chord to conform to the shape of the corresponding roof or structural floor, the layout family’s chord sketch lines must coincide with the top reference plane. The roof/structural floor profile defines the transformation of the family’s reference plane, not the shape of the chord.

  1. Select the attached truss.
  2. Click Modify | Structural Trusses tab Modify Truss panel (Detach Top/Bottom).
  3. Select the roof or structural floor from which to detach.
  4. (Optional) Click Detach All on the Options Bar to detach top and bottom chords.

The truss detaches, retaining its original profile shape. : Attach a Truss to a Roof or Structural Floor | Revit | Autodesk Knowledge Network
