Architectural CAD drawings are usually quite complex, but a long journey begins with a single step. So, how should we get started when we need to create an architectural CAD drawing? This CAD tutorial has compiled an analysis of the relevant drawing processes and is provided to you! Based on the content of architectural CAD drawings, the spatial design in these drawings includes floor plans, elevations, sections, and detail drawings of joints. The drawing sequence is also to start with the plan view, followed by the elevation and section views, and finally to draw the detail drawings of the nodes. In terms of specific procedures, following these steps is required to use Haochen CAD software for architectural drawing. A comprehensive analysis of the entire CAD design process for buildings: 1. Setting up the drawing environment for building floor plans – defining layers, colors, and line styles. Set up auxiliary drawing tools, such as the options in Sketch settings like \"Snap and Grid\", \"Enable Snap\", \"Polar Tracking\", \"Enable Object Snap\", etc. Set dimension style, including setting line and arrow formats, dimension text style, adjusting dimension text and extension symbols, main unit of measurement, and other settings. Other settings, including text style, drawing units, drawing boundaries, etc. Dimensioning styles must be set in accordance with the standards for architectural drawing. Usually, design firms already have pre-set dimensioning styles; generally, simply by copying one of these styles to a new drawing, the style will be automatically imported. Using Haochen CAD Architecture and Haochen Cloud Architecture is even more convenient; the annotation styles built into these software programs are set in accordance with **’s drawing standards, so no additional settings are required. 2. When drawing the grid system, its numbering, and annotations, it is generally necessary to first grasp the overall structure before focusing on the details. Similarly, the most important elements of an entire building are its structural support components; if these components are not positioned correctly, the amount of work required for subsequent modifications becomes enormous. Therefore, to have detailed content, it is necessary to first establish the framework of the building, draw the grid system, and use annotations to determine the positions of the axes. 3. When drawing the support structure, “draw the columns first, then the walls, and finally the doors and windows.” The order of drawing in this step follows the importance of each element in supporting the building structure; vertical load-bearing columns are undoubtedly the most important. Columns can break through walls, whereas walls clearly cannot split columns in half. 4. Draw the stairs, as well as the kitchen and bathrooms. Since the layout of pipelines in the kitchen and bathrooms involves specialized equipment considerations, it is necessary to draw their internal layouts clearly so that they can be submitted promptly to the equipment specialists for design work. Drawing these elements later on will interfere with the design processes of other specialties. 5. Draw architectural elements such as balconies and canopies, which are also essential parts of a building. The drawing process may help us identify some design issues. These components also need to be labeled later on. 6. With the architectural structure that provides separation for dimension markings and written text, we can now proceed with adding the dimensions. During the marking process, it was found that there were errors in the design of the building’s main structure, which needed to be corrected promptly. 7. Drawing elevations and sections: With the floor plan as a basis, it is possible to draw elevations and sections. Usually, the drawing of the floor plan takes the longest time and is also the most important. 8. Draw node details such as door and window lists; when creating these node details, it is necessary to refer to the plan, elevation, and section views, and provide proper indexing. If doors and windows are drawn using HaoChen architectural software, the [Door and Window Table] in the door and window module can be used to select and count them with one click. 9. Improve the graphical annotations and labels; ensure that all indices are included, optimize and trim the grid system, and clearly depict the outdoor environment as well. Most importantly, make sure the printing settings are correct. Note: The information I provided above are just some common settings for drawing floor plans. As for the basic settings for drawing elevation views, sectional views, and detail drawings, they depend on the drawings themselves. 10. Practical application: In actual work, most design firms in China use specialized software for drawing, such as the widely used Haochen CAD Architecture 2020, as well as Haochen Cloud Architecture designed for individual users. The building intelligent objects in these two architectural software programs can **increase your drawing speed. Below is an example of using Haochen Cloud Building Design; isn’t it fast to draw? The above is a summary by the editor regarding the analysis of the drawing process for architectural CAD drawings; I hope it will be helpful to everyone~
