In this case, it can be simpler todo draw over the major áreas of the drawing you wish todo import with your own geometry, divide it up to Suit the bien you intend modeling, and save it into your own clean Cad file, ready for import into Blender. If youre not the creator of the Cad files, you could find that they can be rather inaccurately setup and badly Layered. You could try selecting all and scaling down in Blender, if you forget todo do it in Cad. Clipping Will be evident, panning and zoming Will be near imposible. In fact, you probably wont be able todo se much of it at all. If, for example, you import a large building or site where one Cad unit equals one milímetros, Blender Will have big dificulties displaying all of it. One of Blender peculiarities is the restriction it places on your work space. Scale your prepared drawings todo 1 Cad unit = 1 meter (scaling down by.001, converts millimeters todo meters). There no point importing masses of content you dont ned, it Will only get in the bien and Slow you down.ĭo a global flattening of z-coordinates, it isnt unknown todo have 2d drawings containing stray content with a z-value, the 3rd dimension. All the drawn entities in your Cad files, which are imported into Blender, Will become editable meshes, made up of Edges and vértices.
Removing any drawn información which is unnecessary such as text, landscaping, people silhouettes, tres, bushes, hatching and dimensions (specially drawn content, which are made up of hundreds of tiny bitty lines). Whichever bien you approach modeling your building, the preparation of Cad files may well include: It a los helps todo get some sort of modeling game plan together, before you go any further. This can be important if youre working with someone elses design in order todo interpret their design correctly. As you go th rouge the cleanup process, youll get a fel for the bien the building is put together and a fel for the best bien todo model it. The choice of how you model your building Will probably be dependent on the buildings form and construction. The bien you prepare the files may well depend on the approach you intend taquíng todo modeling your building. Unless you have the privilege of working for a more enlightened practice, with a well-enforced Cad policy, it Will most likely be necessary todo do an amount of cleanup and preparation, in your chosen Cad application, before attempting todo import the files into Blender.
Architectural Cad files are often criticized for being rather large, messy and containing a lot of duplicate or unnecessary información.
