Creating Plan Views and Setting View Properties

Which types of objects are copied when you duplicate a view without detailing? With detailing?


Duplicating a view without detailing leaves out certain elements such as annotations, dimensions, door tags, and window tags. These elements are included when duplicating with detailing.

In both cases, the visibility and graphics settings are carried over. For example, if the furniture lines are set to red in a view that is being copied, they will still be red whether or not the view is duplicated with detailing.

What factors affect whether it is better to duplicate with or without detailing?


Detailing is best used when preparing structural or construction documents. When considering these applications, details like dimensions and door tags are important for designing, planning, and scheduling.

Duplicating without detailing is more useful to convey architectural ideas. This reduces clutter and allows you to focus more clearly on the space being designed.

How would you change the view properties to show clerestory windows with sills located at 6 feet (1.8 meters) above the floor level?


By editing the view range of a plan view and setting the cut plane to 6 feet, we would be able to make the high clerestory windows visible. However, this change may hide lower windows. To fix this, we can create a plan region around the clerestory windows and set the view properties in this region independently of the rest of the view.

Creating Elevation and Section Views

What types of information are typically displayed in: Exterior elevation views? Interior elevation views? Building sections?


Exterior elevation views are useful for showing the architectural details and materials of the building facade and are often used to illustrate the exterior architectural appearance and features.

Interior elevation views are useful for showing the details of elements placed on interior walls, such as moldings, cabinetry, and fixtures.

Building sections are typically used to explain the vertical relationships between building elements and their connection details. They are also useful for displaying the details of vertical shafts and circulation elements, such as stair wells and elevators.

Should you create interior elevations for every room? What features of a room are best illustrated using interior elevations?


Interior elevations are typically not needed unless it is necessary to display a specific aspect of the design that cannot be explained well in a plan view. These features often include moldings, cabinetry, fixtures, appliances, and other interior details where the placement height is best explained in a vertical view.

What are the key differences between elevation and section views?


Elevation and sections views are similar in many ways. The key difference is typically that elevations display an external projection of the elements that appear in the view, where sections are used to display a cut through the key elements.

Creating 3D Views

What happens to the accuracy of objects that appear at the edges as you expand a perspective view's crop region?


When expanding the crop region of a perspective view, the objects near the edges appear to be stretched out. To prevent this, it is important for the focus of the image to be located in the center of the image.

If you want to include a broader view of your model in a perspective view, how should you change the camera placement?


If the view has already been created, you can use the Autodesk SteeringWheels widget walk option to back up and see a broader view. You can also show the camera in a plan view, and then move it farther away from the target object.

Can you use a section box to cut away parts of a perspective view?

Yes. In a 3D perspective view, the section box can be displayed and its edges can be moved in much the same way as in the default 3D view.

Adjusting the Appearance of Elements in a View

What visual styles would you recommend for views that will be printed in construction documents?


Hidden line. This visual style minimizes the visual clutter by obscuring hidden lines and keeps the image simple for printing on noncolor printers.

- Presented to clients to show materials recommendations?


Realistic. This visual style gives the truest representation of selected colors and material appearances.

- Used to check for intersections or interferences between objects?


Wireframe. This visual style enables you to clear see how elements interact and join, even if the edges would be hidden by the surfaces. Wireframe views are similar to X-ray vision.

How are the shadows displayed in your view affected by project location?


The latitude of the project location determines where the sun will be located in the sky at different times of the day and the year. This is reflected in the position of the shadows cast in model views.

- Time of day?


The time of day also affects the position of the sun in the sky\u2014rising from the east in the morning and setting to the west in the afternoon. As the day progresses, the shadows cast in model views change to reflect this position.

- Month of the year?


The month of the year also affects the path of the sun in sky. During the summer months, the sun's path is relatively high in the sky and shadows cast at midday are typically short. During the winter months, the sun's path is relatively low in the sky, and the shadows cast at midday are much longer.
