Revit Interview Question and Answers
Continuation of my previous topic
1. Explain Design Options
Design options is a feature in Revit that allows you to create and manage multiple designs within the same project. By using design options, you can create multiple options within the same space without them conflicting with each other. A design option set is a collection of possible solutions for a particular design problem, and each design option set contains one primary option and one or more secondary options.
2. The difference between hosted and non hosted families
In Revit, families are either hosted or unhosted. A hosted family is one that requires a host element (such as a wall, ceiling, roof, or face) in order to be placed in the model. An unhosted family is one that does not require a host element, but is still hosted by a level.
Some advantages of hosted families are that they can adapt to the changes of the host element, such as its shape, size, or location. Some disadvantages are that they can be more complex to create and manage, and they may not work well with some types of elements, such as floors or ramps.
Some advantages of unhosted families are that they can be more flexible and simple to use, and they can be placed on any type of element. Some disadvantages are that they may not follow the changes of the host element, and they may need to be manually cut with voids or other tools.
To create an unhosted family from a hosted one, you can either build it again from scratch in a non-hosted template, or nest it in another non-hosted family and propagate the parameters.
3. The difference between various hosting options.
In Revit, hosting is the process of attaching an element to another element. The host element provides the support for the hosted element. The hosting options in Revit are face-based, work plane-based, and hosted.
○ Face-based elements are attached to a face of a host element.
○ Work plane-based elements are attached to a work plane that is defined by the user.
○ Hosted elements are attached to a host element.
4. How to create customized hatches
○ Go to Annotate tab > Detail panel > drop-down Region. Click Filled Region. Within the Draw panel, select a sketching tool.
○ Once the filled region is in place, click on it. In the Properties palette, click Edit Type.
○ Create and import custom fill patterns.
Alternatively, you can use a free excel based Revit Hatch Pattern Creation tool to create your own Revit custom hatch patterns of any size.
5. Why is it not recommended to explode CAD in Revit
Exploding linked CAD files that yield more than 10,000 elements is limited in any Revit Version as this may cause file corruption. It is not recommended to explode a CAD file inside Revit because Revit will change all layers into a Linestyle, which means if you have a large CAD file with many layers, you will have loads of dumb, useless linestyles. Even with a complex DWG 3D model brought into a Massing family, you will be unable to explode the imported complex 3D model, since Revit doesn't have any object type for handling NURBS or other complex solid forms.
6. Do you import CAD or link CAD
You can either import a CAD file or you can link it. If you expect the CAD file to change, it is best to link it. If the CAD file is revised, then you can simply reload the linked files in Revit and see those changes. However, if you do not expect the CAD file to change, it is best to Import it.
7. How to control line weight in Revit
To change line weight settings in Revit, you can follow these steps:
○ Click Manage tab Settings panel Additional Settings drop-down (Line Weights).
○ In the Line Weights dialog, click the Model Line Weights, Perspective Line Weights, or Annotation Line Weights tab.
○ Click a cell in the table and enter a value.
○ Click OK.
You can also examine or change the line weight settings by accessing Revit ribbon> Manage tab> Settings panel> Additional Settings> Line Weights2.To change line weight settings for walls, you can go to Visibility/Graphics>Object Styles>Walls.
8. How to use the filter
Filters are a way to select specific elements based on rules you can set with the end goal of overriding the graphics or affecting the visibility. You can create, edit, load and apply filters in Revit using different tools and menus. Filters can be very easy to implement or extremely complex to get to the desired elements1. You can also use filters to find objects in your project by category.
9. How to restore a file
· Start Revit.
· Click Collaborate tab Synchronize panel (Restore Backup).
· In the Browse for Folder dialog, navigate to the copy of the backup folder for the central model (created in step 2), and click Open.
10. What are these shortcut stands for: VG / DI / AL
· VG stands for Visibility/Graphics which controls the visibility and graphic display of model elements, datum elements, and view-specific elements for each view in a project.
· DI stands for Aligned Dimension which creates an aligned dimension.
· AL stands for Spot Elevation which displays the elevation of a selected point.
