CM BIM Exam Flashcards

Improved visualization and Collaboration.

BIM is a process of collecting, manipulating and analyzing information - not just software or technology.

Building Information Modeling.

No.

Spatial CoordinationScheduling Estimating Business Development

Depends on the contract.

Yes.

Regulate models to ensure that they are all in appropriate file formats and are saved with appropriate names, and that (0,0,0) is the same on all models.

A 3D model based on forms rather than lines; includes more than just the shape but also any important relationships that define the form.

Refers to traditional construction drawings on paper that display a building in multiple views, with each view showing only height and width, height and depth or width and depth of the space illustrated in that view. Typical views include floor plans, elevations, section cuts, reflected ceiling plans and details.

The combination of height, width and depth of the space illustrated in that view. This is the basis of building modeling. 3D creates a more realistic view of a space that can be understood by the layperson as well as those versed in construction documents.

Looks similar to a solid model, only without internal information such as volume. Essentially, a face model is just a shell of the outside. This produces a smaller file size, as inside information is not included. Wallpaper is a good example, because its exterior face is extremely thin.

Similar to 3D face, except poly mesh tends to be a single flat plane such as a ground plane.

Represents the entire volume of an object. Mass properties can also be associated with solid models to more closely represent real-world objects such as steel or concrete. If additional information is needed (mass, volume, bounding box, centroid, moments of inertia, products of inertia, radii of gyration, principal moments, etc.), they can be extracted with a click of a button. Solids are the most informationally complete and least ambiguous of the 3D modeling types. Complex solid shapes are also easier to construction and edit than are wireframes and meshes.

The integration of time (scheduling) into the 3D model. This allows for scheduling to be more easily understood by allowing the equivalent to time-lapse photography without actually building the structure.
