[Plugin] Dxf_In v2.2 20110517 Dxf2Skp

Chrisn2011

This may be too late for you but I had used earlier versions of this on an iMac and found that there were sometimes problems which seem to relate to how the file is saved, some operating systems use carriage return -linefeed to denote the end of a line others just used one. I made a mod which allowed it to work on the iMac (see my post of Thu Feb 17, 2011 12:29 am), it may be worth trying it on the new version
I edited the files using Textedit on the mac, just be careful that it doesn't add a .txt extension

To help I have listed the suggested change below

Find the following bit of code in the.rb file

#get all block names, save them along with their location
begin
	aFile=File.open(chosen_file, "r")
rescue
	result=UI.messagebox "<Error> The DriveName\\Path\\FileName.dxf may not\nbe standard ASCII characters. If so, place the Dxf file\nin a ASCII named folder before accessing that file.", MB_OK
end
aFile.each_line do |line|						
	count=count +1
	if count==odd_number					#strip dxf tags thanks to TIG
		odd_number=odd_number + 2
		line=line.strip
	end

	last_line=this_line							#save last line data
	this_line=line

and insert the line
line=line.chomp+"\n"
after
aFile.each_line do |line|
it should ensure that all the data read in is terminated in a way that ruby scripts accept, and it shouldn't affect the way they run under windows either.

I see it in the file menu, and can start an import.
But after a certain time it aborts an I get an error window "<error> or empty File".
I have tried different DXF-Files.

What do I do wrong?

I'm having the same problem. No matter what I do to prepare the file in illustrator, the import dxf dialog in sketchup gives me that error window and quits the import.

Same here: "<Error> or Empty File"
Mac OS X 10.6.8
Sketchup 8.0.16845

Did you read the next post? Maybe it will help since it seems to answer the question.

The best option would be to use the Pro version of SketchUp.

OK, so I added the line=line.chomp+"\n" as described. What does the error message "Database contains Unsupported Entitys: SPLINE" mean? After receiving the message the file continued to import properly.

Upon further inspection my file did not import correctly. It seams to be having trouble with the curves. I've attached the DXF file, a screenshot of the original artwork in Illustrator CS4

and a screenshot of the resulting import into Sketchup 8.

Works flawlessly with SketchUp's native DXF installer.

That means SPLINES are not supported in the plugin, and the arcs in your .dxf are made using splines.

You could covert the file to an older .dxf version using the Teigha converter, and try importing the converted file. Use dxf version R13 or earlier. There will be more cleanup required, but it should convert the splines to a supported entity.

When I export from Illustrator as R13 I get this error message: "*Block U1 contains a unsupported mesh". These are extremely simple paths made up of simple arcs and line segments. Why don't the arcs remain arcs after export?

Dave R

Sounds like a question for the Illustrator people. Do they have a support forum?

The error is from the Dxf_in plugin.

Try FreeDXF: http://sketchucation.com/forums/viewtopic.php?t=22199

FreeDXF does a somewhat better import although still not perfect. These dxf importers are written by amateurs and hobbyists. If you need a Pro importer, your best option is to buy SketchUp Pro or get a commercial importer for SketchUp Free.

ANewBeat

As a work-around, I tried exporting the DXF from a different program (which allows "Save as Arcs" as an option) from my PC and I'm back to the "<Error> or Empty File" message. Ugh.

ANewBeat

I finally got it to work. I had to export the DXF from FlexiSIGN with "Save as Arcs" checked, then convert to R12 via the converter mentioned above. A little convoluted, but I would typically build these types of shapes in FlexiSIGN anyway. When I simply converted the DXF exported from Illustrator I got a few errors and it segmented the arcs. Whew.

HI, I get with SU2014 the following on SU startup

Errore di caricamento del file Dxf_In_v2.2.rb

but the plugin semms to work properly.....

I don't know if it is something I have done wrong or there is an issue with SketchUp 2015. As I looked into the issue I discovered that I had several different versions of SketchUp installed. It seems that the SketchUp developers are not smart enough to remove an older version when installing a newer version. Thus I manually uninstalled all early versions I could find and I think I now only have SketchUp 2015 installed.

The next chore was do find where the plugins are located, scanning my system I found the location to be C:\Users\John\AppData\Roaming\SketchUp\SketchUp 2015\SketchUp\Plugins thus I copied the Dxf_In_v2.2.rb file to this location. Now when I start SketchUp 2015 I get the above error for this extension. Any suggestions? I'm attempting to import some AutoCAD dxf files.

Well, you got that wrong.

They intentionally have SketchUp designed so each version installs separately and doesn't touch the older version. Many people go back and forth between versions, especiallwhen they first install a new version. There's comfort in having something to fall back on if needed. there was certainly no need to uninstall earlier versions. They didn't have anything to do with the error message you have from the plugin trying to load.

Which version of SketchUp 2015 do you have?

driven

as this plugin doesn't work in v2015, you could import into v8, and then, after saving, open in v2015 [ unless you uninstalled v8 for some misguided reason!!! ]...

or you can change the line that's failing and see what comes next...
this is the failing line...

ramFile.each do |@line|	#search for entities @line by @line

it's failing because it uses @ where it no longer works...
so, replace that line :306 in the file
C:/Users/John/AppData/Roaming/SketchUp/SketchUp 2015/SketchUp/Plugins/Dxf_In_v2.2.rb
in with

ramFile.each do |line|	#search for entities line by line

save
and try again...

Hi

I am a serious beginner with sketchup, attempting to bring in a .dxf file that have been exported from QGIS. the file is clipped and not big in size (184kb)

I am working on a mac, in sketchup make 2014, I downloaded the Dxf_in 2.2 and get this error when I start up my sketchup (see attached)

Any advice on what may be wrong.

I have tried to just open a .dxf file through File: Import: <select *dwg /*dxf> file type, but I get an import error(see attached).

Any assistance would be greatly appreciated

the answer is in the post above yours...

or you could use Jim Foltz's FreeDxf plugin in the Plugin Store...

Thanks!
I managed to sort out the first error with your comment above...
I have now tried to deal with thesketchUp error <empty file> issue with an earlier post (see insert below):

Find the following bit of code in the.rb file

#get all block names, save them along with their location
begin
aFile=File.open(chosen_file, "r")
rescue
result=UI.messagebox "<Error> The DriveName\Path\FileName.dxf may not\nbe standard ASCII characters. If so, place the Dxf file\nin a ASCII named folder before accessing that file.", MB_OK
end
aFile.each_line do |line|
count=count +1
if count==odd_number #strip dxf tags thanks to TIG
odd_number=odd_number + 2
line=line.strip
end

last_line=this_line #save last line data
this_line=line

and insert the line
line=line.chomp+"\n"
after
aFile.each_line do |line|
it should ensure that all the data read in is terminated in a way that ruby scripts accept, and it shouldn't affect the way they run under windows either.

But I am still getting the <empty file> error.
Any suggestions on this?
