In this tutorial in english (updated to Blender 2.8) we will observe how to import a DWG file into Blender, after making it a DXF file.

those two file platforms are crucial in the planet of architecture and mechanics because they’re frequently created by CAD programs commonly utilized by architects and designers; there clearly was and so the need certainly to make Blender talk to this environment to be in a position to import models downloaded from the web, to possess 2D plans to extrude to produce complete structures, to texturize and animate 3D models, therefore realizing a preview that is realistic of task completed. Nonetheless, Blender doesn’t have an addon when it comes to direct import of .dwg files, as this will be a proprietary format that is binary specs haven’t been formally released, while rather you have the one which decodes the files of kind . dxf, a format utilized to change information involving the CAD that is various. So we are in need of a device that converts DWG files to DXF files. In this guide we shall first show how exactly to transform a DWG file into a DXF file, then simple tips to import the DXF file into Blender and exactly how to do some operations to show every thing into a mesh. By the end some issues that might arise plus some feasible solutions should be presented.

As being a test to utilize into the guide, we shall attempt to import this 2D map, contained in a more technical task conserved in a DWG format file:

Note: if you created the DWG file or perhaps you have actually the chance to change it, make every effort to focus the drawings into the axis beginning, to completely clean within the project from lights, proportions and writings, to lessen the sheer number of levels, and lastly to transform the scale into meters.

Convert a DWG file to a DXF file:

A premise that is small the DXF structure has not yet for ages been acceptably updated utilizing the growth of the DWG structure, therefore it can happen that help for complex and higher level things and structures is not implemented when you look at the DXF structure, particularly in the older variations. To transform the file from DWG to DXF we will make use of the ODA that is free File pc software (once called Teigha File Converter), which you yourself can install from www.opendesign.com, developed by the Open Design Alliance, a non-profit consortium that dealt because of the reverse engineering for the DWG structure, additionally producing probably the most famous available supply libraries for the decoding. The application can be obtained for Linux, MacOS X and Windows We install and begin this system

Pick using the “. ” buttons the directories in which the files to be transformed can be found and in which you need the files become placed in .dxf structure; if one or more .dwg file is contained in the input directory “Input Folder”, they shall all be transformed and conserved when you look at the “Output Folder” production directory. If the “Recourse folders” option was set, the files is likewise sought out within the subdirectories associated with the input directory. (The “Audit” option can be used to do a check and fix task regarding the input files). Therefore let us select the “R12 ASCII DXF” format ( possibly even R14 could possibly be good, however it depends upon the sort of elements within the task) and we perform the transformation.

Import the DXF file:

We begin Blender, pressing the “A” key we select all of the elements current (lamp, digital digital camera and cube) and pushing the “X” key we delete them. We push on “7” within the numeric keypad, therefore choosing the “Top Orthographic” view. We activate the addon “Import AutoCAD DXF Format” in Edit > Preferences > Add-ons (the one without warning signal if it is not already present)

Through the main menu at the very best, select File > Import > Autocad DXF to load the .dxf file (the version that is current of addon is 0.9.6)

The “Blender File View” window will show up also to just the right you can observe the various import choices:

They suggest how a elements that are various in the DXF file will undoubtedly be encoded and represented in Blender: the way the sets of symbols and things that represent the Autocad obstructs is likely to be grouped, how a layers will undoubtedly be coded, if the auxiliary items needs to be represented or perhaps not, while the resulting elements should be represented, which coordinate system can be used.

We usually do not change the options, we load the file and following a moments that are few plan it the effect appears, however with extraneous converging lines

exactly exactly What took place? If we zoom down (a great deal of zoom out), we realize that the map ended up being really brought in, but you will find these extra lines

They are in correspondence of the text, so let’s try to import the file again, but removing the check for “Import Text as you can see”
