Descriptive Paragraph This image show us a modern city at night. In this picture we can see a lighted street, and this street has a lot of traffic. This street should be a principal street. The buildings have blue windows and gray walls, which give us a sensation of a modern city with big buildings, and have gardens with green grass and trees.

This street has a wide sidewalk, there are many beams of light. It looks like a business street. It has four lanes in the way, the street has two directions with two lanes each one. There are many people walking in the sidewalks, which is very wide.

**Metaverse Paragraph ** Atelier to e-telier and Tech Briefs are interesting articles useful for architects. Atelier to e-telier has a positive aspects like do work easier because students and teachers aren't forced to join to correct or do a job. They can send the assignment by e-mail and so they can work together without being together.

Into the positive aspects of Tech Briefs are the visualization of designs prior to their construction, and another important aspect is the economic because if the project and mock-ups have mistakes, that can be changed and we don’t lost money.

In the negative aspects of this articles are: the people can be isolated and not talk with the others just because it’s more comfortable to work from your house, and the limitations of the virtual-reality process for lighting analysis. Contrast ratios below what’s perceptible by the human eye block out shadows and highlights in the 3D environment that people would normally see in a real room.

**Tech Briefs **

Justice may be blind, but some federal judges in Mississippi have been seeing in 3D. In recent months, they’ve been part of a pilot project launched by the General Services Administration (GSA) to use virtual reality in the design process. Sponsors of the pilot project hope the design team and client can flag problems with sight lines, lighting, and materials before the courtroom is built, to avoid retrofits or costly change orders.

To visualize designs prior to construction—which is key for preventing problems with sight lines among the various courtroom parties—clients typically review 2D drawings and crude plywood mock-ups costing $50,000 or more to build.

Some of the limitations of the virtual-reality process for lighting analysis. Contrast ratios below what’s perceptible by the human eye block out shadows and highlights in the 3D environment that people would normally see in a real room.

I agree because my article is about Virtual reality and digital modeling, to visualize designs prior to construction. And this is very important and economic, even though it has some limitations such as virtual-reality process for lighting analysis.

CAD & BIM Design  CAD (Computer-Aided Design). Is the use of computer technology for the process of design and design-documentation while BIM (Building Information Modeling) is the process of generating and managing building data during its life cycle.

<span style="font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 16px;">These are two very interesting programs. CAD and BIM are programs for architects. That programs let us planes, design and do digital projects.

<span style="font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 16px;">The difference in these programs is: in BIM changes in any plan are applied automatically in all project but in CAD any modification in any plan should be applied in the rest of the planes.
