[Plugin] FreeDXF Importer

[Jim]

Thank you for verifying, John.

[abbis]

Ah!

Thank you very much John! The mounted volume seems to have been the issue. I can import the file fine now. Thanks Jim, I will install the 0.11.2 and give that a try shortly.

First of all, thanks a lot for your plugin, Jim.

Just a query about the Teihga converter.
The dwg import option doesn't work (with SKU 2015 Make and latest FreeDXF v.0.11.2).
The Teigha has been installed in the default folder, and works fine. However, in SKU when I try to import a dwg file, that format is not available in the dialog box (only the "Cad files" option for dxf files), as if the plugin doesn't grab the converter.

Does anyone solved the same issue?

Many thanks in advance for your help.

are you importing from the Extensions or File menu item ?

through the Extensions (the dwg format is not available in FreeDXF Importer plugin)

I looked into the Ruby file "teigha.rb". Is it required an additional file or library called "fileutils"? If so, that file is missing inside "jf-freedxf" folder.

require "fileutils"

module JF
  module FreeDXF
    module Teigha

      # Teigha Command Line Format is;
      #   Quoted Input Folder
      #   Quoted Output Folder
      #   Output_version {"ACAD9","ACAD10","ACAD12", "ACAD13","ACAD14", "ACAD2000","ACAD2004", "ACAD2007","ACAD2010"}
      #   Output File type {"DWG","DXF","DXB"}
      #   Recurse Input Folder {"0","1"}
      #   Audit each file {"0","1"}
      #   [optional] Input file filter (default;"*.DWG;*.DXF") (Use File.basename(filename))

       if Sketchup.platform == ;platform_win
          EXE = "C;/Program Files (x86)/ODA/Teigha File Converter 4.01.0/TeighaFileConverter.exe"
       else
          EXE = "/Applications/TeighaFileConverter.app/Contents/MacOS/TeighaFileConverter"
       end

In my WIN 8.1 Pro, the Teigha sofware is installed in the default folder too:

C;/Program Files (x86)/ODA/Teigha File Converter 4.01.0/TeighaFileConverter.exe

Cheers!

I have some update!

You can select a .dwg or a .dxf file and it should import...

@unknownuser said:

that's in the SU Ruby folder, so it's already available from there...

have you tried it with 'Ruby Console' open to see if there are any error messages?

the other thing to try is doing the conversion directly in TeighaFileConverter, if it fails there you may get a reason given...

[Jim]

Actually, I don't think fileutils is needed. I think I was going to use some methods in fileutils to search for the Teigha converter on the disk drive, but haven't got back to it.

You can remove or comment out the line.

[mgate]

neither working if commented out the "fileutils" line.

I have a folder with two files in dxf and dwg formats:

Once opened the "FreeDXF v.0.11.2" pop-up window, there is only the dxf file (the dwg file is not available):

Is there a problem with "extra extensions"?

def self.select_file(extra_extensions = "")
      title     = 'FreeDXF Select DXF File'
      directory = nil
      # filename  = 'DXF|*.dxf|DWG|*.dwg||'
      filenames = "Cad Files|*.dxf" + extra_extensions + "||"
      file_path = UI.openpanel(title, directory, filenames)
      if file_path.nil?
        return nil
      else
        file_path.tr!('\\', '/')
        @last_selected_file = file_path
        return file_path
      end
    end

    def self.main
       puts "\nFreeDXF debugging ON." if $JFDEBUG
       extra_extensions = Teigha.available? ? ";*.dwg" ; ""
       file_path = select_file(extra_extensions)
       return if file_path.nil?
       #file_path.downcase!
       if file_path.end_with?(".dwg")
          Teigha.dialog()
          file_path = Teigha.convert(file_path)
          if file_path.nil?
             puts "dxf file was not created."
             return
          end
       end

Any idea how to solve?
Another way is to convert dwg files manually with TeighaFileConverter, and then use FreeDXF plugin in SKU.
Sorry to snoop around your codes

[Jim]

This appears to be due to a difference between SketchUp 15 and SketchUp 16 UI.openpanel behavior.

As a short-term work-around, can you try to enter a * then press ENTER in the filename dropdown to force all files to be listed?

Hello Jim
A couple of days ago I posted a request for a plugin that would import measurements directly from a 3D Laser "Leica Disto S910 " in order to draw direct on site.

http://sketchucation.com/forums/viewtopic.php?f=323%26amp;t=64830%26amp;p=594596#p594596

Could your plugin be developed to do the Job ?
Thanks for your response

Nice plugin, works much better than the SketchupPro import. However, there's a few things I've noticed:

• It does not respect blocks' scaling / orientation properly: blocks that were mirrored in the original DXF sometimes end up in strange positions (this does not happen with the other import).

• Perhaps related to the last issue, sometimes I saw blocks that had the proper orientation but had ellipse elements that were rotated in 90 or 180 degrees.

• Layer colors? Why doesn't it keep the DXF layer colors the way the sketchup-included DXF importer does? Currently I work around this by importing it with one (to get the layer colors) and then delete all the geometry/components and reimport with yours, would be awesome to not have to do this.

• It would be nice if the import also preserved layer visibility, or have a toggle to choose on import. Currently it sets all the layers to visible.

• Another toggle to merge DXF layer 0 to sketchup's Layer0 would be handy too.

• Is it possible for it to keep polylines? I don't know if it's a DXF limitation or Sketchup or what. Polylines would be a godsend!

I'm on SketchUp 2016 and macOS 10.11.6 in case that's relevant...

Hi Kuu, thanks for the feedback.

It does not respect blocks' scaling / orientation properly: blocks that were mirrored in the original DXF sometimes end up in strange positions (this does not happen with the other import).

Could you provide a minimal .dxf example file, and example result?

Perhaps related to the last issue, sometimes I saw blocks that had the proper orientation but had ellipse elements that were rotated in 90 or 180 degrees.

Maybe related, maybe not - ellipses have proven difficult to crack but it's been awhile since I've had a look at it. Again, a minimal sample file demonstrating an incorrect ellipse would be helpful.

Layer colors? Visibility?

I wrote this long before SketchUp had support for setting layer colors. Now it does. Can have a look.

Good evening.
I have installed the latest version freeDXF 16th in Sketchup 2016, but I can not
to import any DXF files.
I tried to install the older version of freeDXF but nothing has changed.
Some solution?

If you open the Ruby Console before attempting to import using FreeDXF, then are there any errors that appear?

[Elektro]

Hello Jim.
No before pressing 'Import' in Ruby Console nothing appears, but after I pressed the 'Import' button appears this error:

Oh so it's an encoding issue. Can you share the file here or in a private message? I don't have an example with which to work out a solution.

Hello Jim I have attached the file you that I can not open in Sketchup 2016.
If this can be of help, this file was saved as 'AutoCAD 2013 Compatible DXF (*.dxf)

File_1.dxf

[Jim]

One thing you can try while I work on a fix is to open the .dxf file in an editor such as Notepad++, set the encoding to utf-8, then save the file. It should import correctly.

But might lose some characters such as this one:

puts "\x90".force_encoding("cp1251").encode("utf-8")

I did the test that you have advised me, but nothing has changed.
Instead I have converted the files in ANSI, I saved it, and then I imported into Sketchup and ...... cheers now works.
