      Ah yes sorry this makes more sense:
      Error: #<Encoding::UndefinedConversionError: "\x81" to UTF-8 in conversion from Windows-1252 to UTF-8>

        This error is because I am guessing all DXF files are encoded using Windows-1252 which is not always correct. However, I don't know of a way to guess the encoding of the files in order to read them correctly in Ruby. From what I have found it is not easy.

        If you need a quick fix you can try re-encoding the file in a text editor such as Notepad++ (see just a few posts previous).

        I am interested in having the file so I can check the HEADER section. The HEADER section of DXF files may have the correct encoding. Can you share it here or in a private message?

        Hi

          Is there any way to get old plugins, specifically 0.57? I have some training material that uses SketchUp 8.0 and OpenStudio to do some energy modeling and the training material uses the FreeDXF 0.57 to import some DXF files.

          I would like to try using the existing training material without having to go through and find out what is different so that I can concentrate on the concepts and not the software.

          I saw that Jim has a site on GitHub but I didn't see any old releases there. I've tried searching all over with Google but I can't find it anywhere.

            Hi Gus,

            You will need to wait until this afternoon but I can send you a version that works in SketchUp 8.

                Jim, would your importer be written in C/C++ by any chance? If so, how much of a stretch would it be to get it to work in LO?

                  Well, it would be a huge stretch as FreeDXF is a Ruby extension. I don't have plans to re-write it as a C/C++ extension.

                    I did some more digging around and finally found the FreeDFX-v0.57 plugin that I was looking for that works with my training materials. Is there somewhere I can upload it to so that others can find it as well?

                        Here is the FreeDXF-0.57 plugin for use with SketchUp 8.0 It is needed to go with the training materials for the California Energy Commission (CEC) CBECC-Com energy modeling software using the OpenStudio plugin for SketchUp.

                          I'm having an issue getting this to work on a DXF file saved as 2010 version. I get this error in the Ruby console when I try to import:

                          Any ideas what is going on?

                            Until Jim fixes it...
                            I suspect you have a piece of Mtext in the DXF which is flaky.
                            Currently the code checks if its 'sting' is empty before continuing, but it doesn't check if it exists !
                            Edit the file using Notepad++ [TextWrangler on MAC].
                            Find line 1014 and edit it as follows...
                            return if txt.empty?
                            should become...
                            return if txt.nil?; return if txt.empty?

                            There might be other instances of this in the code ?
                            You can search for the other three uses of .empty? and ensure that before each test the existence of the relevant reference with .nil? is invoked. One is already trapped with a return, the next one needs a similar line adding as a fix. The line reading next if l.empty? needs a preceding **next** if l.nil? as that is inside a 'block' rather than in a 'method' and so it should not have a return.

                            TIG

                              I tried to import a .dxf file saved from Inkscape as an Autocad DXF R14 format and nothing happens.

                                  Jim decided to no longer support it, and it's no longer available from the PluginStore.

                                  As it's an RB file you can edit it using a plain-text editor like Notepad++.
                                  C:/Users/Resource/AppData/Roaming/SketchUp/SketchUp 2017/SketchUp/Plugins/freedxf/**freedxf.rb**
                                  Do this only for yourself, because posting or distributing an altered version might infringe the author's copyright?

                                  The allowable syntax in ' case' structures changed with newer Ruby versions...
                                  Find the lines throwing the error, they seem to start around line #658 - e.g.
                                  when 1**:** v = [0 , -h]
                                  and replace the : (colon) with a ; (semicolon) so it becomes:
                                  when 1**;** v = [0 , -h]

                                  Repeat this editing for all of the other when lines which include the troublesome **:**

                                  Save the changed RB file and restart SketchUp...
                                  See if the error has be sidestepped...

                                  If not. then report the next set of error-messages !

                                    Hi!
                                    My friend has a problem with this plugin. Installed properly, using SketchUp 17 on Win10. She can choose a file to import but when she clicks Import in the plugin window, nothing happens. We tried to export an AutoCAD file into a few kinds of DXF but none of them worked. What could it be?

                                      Hello Jim,

                                      Off lately your link to download this plugin doesn't work, there must be some issue here. cause when I search for the same it shows no result in the store. Now I am at a dead end with my work.
