Modelação e Visualização Tridimensional em Arquitetura

In this class, the professor explained some of our doubts about the work and the lessons.

In the 21st of April class we learned: -Types of Extrude : Normal - Perpendicular to the plan we want to extrude; Direction - follows the direction of a line; Path - follows the path of a line; Angle - follows the inclination of an angle; - Command Region ; - Command Edgesurf ; - How to give thickness to a surface; - Command Loft . First, we did some surfaces and solids using the command Extrude . The first one was a normal Extrude, where the extension is created perpendicularly to the plan . The second one follows the direction of a line , defined by 2 points, even if the plan is oblique .  The third one follows the path of a line , whatever direction it is, if it's curved, straight, oblique... The last one follows the inclination of a certain angle , that we give. Then, we learned that we can Extrude not only surfaces, but also lines , like a half circunference. And how to Subtract part

In this class we learned how to: - create spiral surfaces , such as a Helix ; - Subtract spiral surfaces from other surfaces; - draw a surface similar to Guggenheim Museum . First, we drew a spiral , using the command Helix , with center in x,y coordinates 30, 30, base radius with 20 units, top radius with 20 units, and height with 40 units. And then added a box covering all the spiral. And how can we give thickness to this helix? First we draw a circle with center in the starting point of the helix, and 3DRotate for it to be perpendicular to the spiral line. Then, we use the command Extrude , using the option Path and we select the helix. After this step, we added the box. And using the command Subtract , we created some empty spaces in this box, where the helix was. Here's another example: Then, we repeated the same process, but instead of using a circle to give thickness to the helix, we used a square , to
