[Plugin] Dxf_In v2.2 20110517 Dxf2Skp

honoluludesktop

V1.10 places a rescaled dxf model on the mouse pointer.

Options menu
The import file name is in the upper left. Check update take you to the top of this topic's page, and import units include metric as well as imperial scales. Import origins are placed on SU's origin, or subject to the mouse pointer. The default import is for closed polylines to faces, however this may be turned off. Dxf colors by Acad number is also the default, SU names, SU's model materials, or none may be selected.

I think all the interface issues have been addressed. I do not intend to add other entities (perhaps only as requested).

V 1.14 includes minor interface refinements, and the "help option" to save current option selections. Below is a example of an imported 3d polymesh whose definition name is created from the name of the file.dxf.

Honoluludesktop,
How do I get a copy of your DXF importer plugin? It looks like just the thing I need.
Thanks,
Jim B

the terrain looks perfect...

Hello Honoluludesktop...First THANK YOU..for this great plug-in..
my DXF when imported to SKU8 comes flat i.e. the Z height comes at zero..yet when I imported to the 7.1 version comes with the right heights..?
Thanks in advance for your input..

honoluludesktop

Can you post the dxf here? The only Dxf_In entities that default to z=0 are LWPolylines.

honoluludesktop

Hmmmmm..... The dxf reference has a LWPolyline code "elevation" that I had not previously taken into account. Try the attached Dxf_In, and let me know if it works or not. Don't forget to post your dxf file.

HHF, This is the file as translated by an Acad Viewer. The viewer is v2000. I also read the dxf file, and couldn't find the kind of information used to update Dxf_In_v1.18 as part of the new file's entities. Perhaps you shouldn't explode the drawing, and just export it to Dxf as is. Which version of Acad did you use to make the dxf?

HHF

Hello Honoluludesktop..
Not exploding the file was good advice ...it came out nice, ..to answer your question the prefered sofware is Datacad (to me it is more powerful than Autocad..sorry guys!!). It can export any file to DWG and DXF format latest versions..in this instance DXF was saved to version 2002
Thanks again for this wonderful Plug-In it gave me a lot of possiblities...please enjoy your holidays!!

HHF

I tried v1.17..it did not work either..I am also attaching the DXF ..look forward for your comments...Thanks,

HHF

Aloha!..it worked ! ..however I tried a more complex file and it did not come out right (picture #2) I exploded every line before converting to DXF and may have missed something in the midst... I am attaching the the new DXF for your review..
Thank you again for all your input..Happy Holidays..

First off thanks for the import utility!

Been trying to import a dxf from stock drive products of a timing pulley. Unfortunately only 1 line in the drawing makes it. Did not get any errors or unsupported entities so not exactly sure what happened...

Can you take a look at it?

(image of the part and dxf attached.)

honoluludesktop

Hi wireb, I do not see the image or file. Btw, what version of Dxf_In did you use?

wireb

Version 1.18 and not sure why I cannot attach anything.

Here is a link to the cad download page for the part I am trying to import.
http://catalog.catalogds.com/catalog/showPart?mfid=sdp&pn=A+6Z+3-78SF03716
i chose the "DXF file (.dxf)" option.
I also verified I can open the file in a dxf viewer so 99% sure the copy I have is good.

Thanks again for taking a look. It's a simple part so can draw from scratch if I need to. But use quite a few parts from them so would be nice if I could get them to import so I have a base to draw from.

wireb, The dxf is a database with 2d entities created by pro/engineer as ACAD Dxf version 14.

999 Pro/ENGINEER 2005030 by Parametric Technology Corporation . . $ACADVER 1 AC1014
In the attached portion regarding a LINE from the Dxf file, note the sequence of tags 10, 20, 11, 21. These are probably coordinates from the start of the line x,y to its end x,y. Dxf_In supports and Acad Dxf v14 requires for LINE, 10, 20, 30, 11, 21, 31 (start at x,y,z to end at x,y,z).

0 LINE 5 212 100 AcDbEntity 8 DEFAULT_2 100 AcDbLine 62 8 6 HIDDEN 10 11.9420742236 20 13.5330979028 11 11.9201184463 21 13.4944728974 0
I guess the reader you used overlooks this. One Acad viewer I tried rejects the file, and another non-acad viewer produced the attached 3d view of the file. Is it correct?

Notice how the model is floating above x=0,y=0,z=0 origin? Is that also correct? If there is any possibility for Dxf_In to accommodate this file, I need to know what it should look like. Finally, your Dxf includes the entity SPLINE, that Sketchup doesn't support. Dxf_In would have to change it into a polyline (a line segment made up of many stright lines) to import it. Is this OK?

Btw, I think the reason you can not upload files is that as a new user, you are being temporarily blocked from uploading just in case you are a spam. Ask admin to turn on your privileges.

wireb

Yep that looks like the part (cog belt pulley (only 2 teeth are shown)

Segmented lines are fine by me. I can go in and touch them up manually while I am turning the 2d drawing back into a 3d part.

I think the z axis is undefined since this is a 2d print. You can lay it out at z=0 (or any value for that mater) The print is going to get cut down to just that center part (big circle) then pushed / pulled back into the 3d part. So will be moved around quite a bit.

Thanks much for taking a look at this!!
