Two: the units in which we create our blocks must be checked, as they must coincide with the units in which we normally work.

One: it is preferable to create the entire block in layer 0, and thanks to this precaution, if we insert a block of a bed or a table in the 'furniture' layer, for example, the inserted block acquires said layer, so that when we manage the layers, activating or deactivating them, the inserted bed will behave like the rest of the elements in that layer. When we produce a design or drawing in order to use it subsequently as a block, the following rules must be taken into account as a minimum for optimum use of blocks: Once modified and saved, it will be automatically changed in the remaining blocks since it is a single entity. There is another parallel advantage to this, whereby if some of the blocks in our drawing need to be altered, the change only needs to be made in some of them, through the block editor. dxf versions with the business aim of projects stipulating the need for their products or technical solutions and offering them on their websites.ДЄnother advantage of using AutoCAD blocks is saving space in the file since only the data for one single block or block entity is stored regardless of whether it is repeated 2 or 20 times. In addition, companies that manufacture products or construction systems often create their own product libraries in. Reuse of AutoCAD blocks is not restricted to our own designs, since logically, we can also use any block or CAD file produced by third parties if their use is permitted in our project. The main advantage lies in the significant amount of time saved when developing our technical projects, thus allowing better quality graphic representations. In subsequent projects where the same object is required, instead of drawing it again, it is reused by inserting it in the CAD file in which we are working. Now, thanks to the blocks, this CAD drawing only needs to be produced once, the first time it is needed. It can be inserted into the existing drawing to complete it, complement it and help us save time in our CAD project.Д¬AD blocks arose as a result of the need for repetitive use of multiple objects in different projects. Something as simple as this creates enormous advantages over the traditional construction of technical projects, allowing infinite possibilities, since once we have produced any design,

AutoCAD blocks, or those from any other CAD program, are files that can be inserted in other CAD files, it's that simple.
