[Plugin] Dxf_In v2.2 20110517 Dxf2Skp
-
Hmmm........Turned out to be easier to rewrite then to explain (as above).>_< Attached is Dxf_In that triangulates non coplaner 3DFACE(s). It is still to your advantage to fix "Dxf Out" in order to maintain compatibility with AutoCad. In addition, ODA/SU7 locates the translated model on SU(s) ground plane, where Dxf_In elevates it as specified. Where is the original model located in reference to the world origin? Btw: please check your pm (private mail).
Can you pm me an image of your model as it is created by your original application? -
This version allows the following non Acad compliant Dxf information to be processed:
01/10/2011 - v 1.20 Convert lower case Dxf entity names to upper case.
01/12/2011 - v 1.22 Triangulate Dxf 3DFACE when not coplaner. -
Perfect plugin to go from GIS to SketchUp when the ArcGIS->Skp6 plugin doesn't work. You've done fantastic work and you should get more recognition for it!

I am trying to get topographic contour lines into SU8 as vectors. Illustrator (AI) can "trace" raster images from topo maps very nicely, but then I cannot get the results into SU8.
--I created a simple filled 2-d square in AI,
--exported that as a dxf with the "AutoCAD version 2004/2005/2006" option in the AI export dialog.
--I used your plug-in (my_dxf_In_v1.22.rb) to import this file into SU8,
--and get the SU error "<Error> or Empty File".
--I tried the other export->CAD options from AI to no avail.
--Also, "polylines to faces" or "polylines to edges" made no difference.Any suggestions? Do you think AI is exporting "non-Acad-compliant" dxf?
-
It is possible that AI exports drawing entities that Dxf_In doesn't currently support. Upload the dxf file that fails to import (smaller the better), and I will look at it. Also, describe, or upload a image of the original illustration.

Here are 4 files for your experimentation/troubleshooting :
1.the DXF export from (1) DXF export from AI contours
2.png of (1) so you can see what the DXF is supposed to show
3.DXF export from AI of a simple, 2D square - black stroke, white fill. DXF export of filled square
4.screenshot of AI-DXF export settingsThe AI file of topo contours file would not upload; but if you can use it, I could email it to you.
Thanks for the help! -
Sorry for my lack of vocabulary here-- If the splines (curved lines) in AI were converted to a series of small straight line segments, then perhaps they would be Polylines in the dxf?
I was not able to import square.dxf, the same file you imported successfully! Any ideas? Thank you! -
As you probably know, SketchUp can not model curves, and approximates them as a sequence of short connected lines. A spline is a complicated curve, and a polyline is a sequence of connected lines. Btw, Sketchup's basic entities only include faces (planer surfaces) and edges (lines). I am not mathematically fluent, and probably butchered the explanation.
AI exported the topo as Dxf v2004-6 splines. If you use the ODA translator and convert AI's Dxf v2004-6 to Dxf v12, the Dxf splines will convert to a Dxf polyline.
3watersheds-topo-SIMPLE-v12.dxf
The image I posted above is an example of that. Because AI incorrectly tags the splines as closed, the exported topo line are closed. That however, can be easily corrected in SketchUp as below.
If you can get AI to export the topo as Dxf v12, the topo will export as polylines. I did not see this option on your image of the AI menu. In addition, if AI can export the topo as either Dxf lines, polylines, arcs, or lwpolylines, Dxf_In will be able to import them into SketchUp. However, I did not see these options in the AI menu either.I don't know why you are unable to import square.dxf, did you get any error messages? If so, screen capture the messages and post them here. If you did not get any error messages, open Sketchup, from the SketchUp menu select Window > Ruby Console. Then attempt to import square.dxf. If you get an error message in the Ruby Console, screen capture that message and upload it here.

gwied, I have looked at 3watersheds-topo-SIMPLE.dxf, and found that it consist of splines. Dxf_In doesn't support splines at this time, and unfortunately, I will not be able to add it to the translator any time in the near future.
I understand that Dxf v12 writes splines as ploylines. ODA provides a Dxf/Dwg translator here that will convert your Dxf v2000+ into Dxf v12. Dxf_In can then be used to import Dxf v12 into SketchUp. Select Dxf_In option: polylines to edges.
Dxf_In will however, translate the entities in square.dxf.See the help option for a list of entities that Dxf_In supports.
-
Hmmmm..........In regards to square.dxf, I just noticed that your OS, and hardware are Mac. I don't believe that I have ever had a request for support from a Mac user before. Perhaps that is the problem. Plugins that run on a PC do not always run in a Mac (as well as the other way around). For me to attempt to solve this kind of problem, it would help to have the error message that is reported in the Ruby Console. Perhaps fortunately, the ODA translator support specific Mac OS's. You need to verify it with your OS.

I always wonder when there are no replies yet a bunch of downloads, why those who downloaded don't take (or have?) the time to send some love to the author. I have no use for this plugin, but here's some love.
awesome work on that plugin!

Hi,
I'm a bit new to Sketchup, but have used other CAD packages in the past. I was wanting to load a DXF file into Sketchup, but as 8.0 doen't have a DXF importer I looked at other options, this seemed the best.I have just downloaded dxf_in_v1.18c, copied it and pasted it with other plugins
It seems to start ok asks for the settings
Help options:
Import unit:
Select Origin:
Polylines:
Materials:
which I set to None, Millimetres, Model's, to Faces; by Number, and after it failed tried the AmericanFlag1.dxf from Jim's lots of DXF files (earlier in this topic) and still get the same problem, even changing some of the settings I still get the same problem, a Sketchup dialog stating <Error> or empty fileThe import runs through stages1 and 2 with an indicator running across the bottom of the screen, so I assume it is reading the .dxf file OK. Have I set something up wrong?
I couldn't find an older version of dxf_in to see if there was any difference.Any advice or comments greatly appreciated.

Chris, There are 3 things you can do. First download (from the first post in this topic), and use the current version Dxf_In v1.22. If that fails, post the problem "AmericanFlag1.dxf" here so that I can examine the file (In the post a reply window, "upload attachment" tab is located on the left side, below the reply box). I see that you use a Mac. I have never tested the plugin on a Mac. Plugins that run on PC may not run on Macs, or the other way around. For me to fix a Mac related problem, I need your help. Open sketchup, turn on the "Ruby Console", run Dxf_In, then copy the error message from the Ruby Console, and upload it here.
In any case, upload "AmericanFlag1.dxf" for me to look at, I was unable to find it in Jim's earlier link.

Hi, I have been doing some tests and have discovered that the Mac appears to be bringing the data from the file with a Carriage Return Line Feed termination, and as such was not being recognised. I found the following modification made a huge difference
#get all block names, save them along with their location aFile = File.open(chosen_file, "r") aFile.each_line do |line|
line=line.chomp+"\n" #strip CRLF and replace with LF
count = count +1
if count == odd_number #strip dxf tags thanks to TIG
odd_number = odd_number + 2
line = line.strip
endI will try this on the current version. As far as I can see from my studying of Ruby that alteration should not affect running under Windows as it will strip any terminations from the line and then replace it with the LineFeed value used everywhere else in the code.
The fix allowed me to load the "AmericanFlag1.dxf", I got some bad polyline error, but it did complete the loading and could be seen in Sketchup.
It is here and I will test the new version against it and try and capture the message from the Ruby console.Chris

Chris, Thanks for the dxf, it failed to translate on my pc system. I currently have some work that pays the rent, and may not get back to you for a couple of days, but, I will ASAP. The problem may not be a PC vs. Mac situation. A quick look at the the dxf indicates that the problem may be easily fixed. I will post a solution, or an explanation as soon as I pay the rent:-)
The image appears not very sharp.

Chris, The problem is simple. Your file $ACADVER version number is AC1003. The Acad Dxf documentation doesn't identify this version. I suspect that it is prior to Acad v10, and may even have been made with a non-Acad program. It contains the drawing entity "polyline" in a 2d format. Dxf_In only reads 3d entities. It will be a while before I can revise Dxf_In to accommodate 2d entities. I suggest that you convert AmericanFlag1.Dxf v?? to AmericanFlag1.Dxf v2000 with Teigha File Converter linked here. The converter will change the 2d polylines to 3d so that Dxf_In can read them. The free converter is by ODA, and I believe it is the same engine that SketchUp uses in its Pro Dxf importer. For output, select "2000 ASCII DXF". The converter is designed to batch convert all the DXF and/or Dwg files in one folder into another folder.
I have attached the v2000 Dxf file below, give it a try on your Mac and let me know if it works. If not, open the SketchUp "Ruby Console". run Dxf_In again, and if you get a error message in the "Ruby Console", upload a copy of it to me.

Many AutoCad entities like line, arc, and circle have properties unlike those in SketchUp. For example a Acad line can have thickness, and a extrusion direction. A basic Acad line is like a SketchUp line or edge, but when it has thickness, it has 4 sides, like that of a SketchUp face. When a thick line has a Acad extrusion direction, in Sketchup that line resembles a parallelogram. In addition, a Acad polyline has thickness, and will resemble an rectangular volume in SketchUp.
Dxf_In currently supports thickness, and width when required by users in some entities.
The following image is a Dxf_In import of a file that translates lines, arcs, and polylines (stright lines only) with thickness.
The next image is a SketchUp import of the same file translating lines, arcs, and (below) a polyline with thickness and other properties.
The last image is the same files opened in a Acad viewer. It adds width, and other properties to the model. -
Honoluludesktop: thank you very much for this plugin
one thing though, i tested on a file and i saw that the it doesn't import the text intro SU.
could you adjust that please, also if it is possible to add the possibility to maintain the Cad Layers on SU, after the import.
thanks a tonne! -
Hi Alex, Go here for a plugin to import text separately into your SketchUp model. Can you post the dxf file so that I can work on layers?

here is the pdf of what should appear in SU , but only in CAD, as DraftSight, which is new and free sees :
