ARCHICAD is an architecture program of BIM Technology (Building Information Modeling). The BIM concept is based on the use of 3D modeling with construction information, which generates automatic drawings of floor plans, sections, façades, and details from a two-dimensional reading of the model.   The video lessons are divided into 10 sections (5 sections in this Part 1), where a house project is done from the beginning to the end: we start by presenting BIM concepts, we show the use of DWG reference drawings for terrain modeling, structure modeling, walls, doors and windows, roof, 2D drawings settings (floor plans, sections, façades, etc.), arrangement of the project boards, publication in PDF / DWG and Rendering. Check out the class schedule (PART 1): Section 1: Basic Concepts, Work Environment and Tools; Section 2: Project Beginning, DWG References, Terrain, Structure; Section 3: Structure, Stairs and Ramps; Section 4: Terrain: Cut and Embankment, Walls, Element Attributes; Section 5: Doors, Windows, 3D Sections and Curtain Wall;
