[Plugin] importDXFtext

Miner_Jeff

Hello,

I realize this is a an old thread. Anyone else having issues trying to use this with Sketchup make 2015?
I get a crash shortly after invoking the script in the console, goes straight to bugsplat reporting.

Thanks Tig for all your selflessness in sharing of your ruby programming skills.

Cheers,

Can you shared the text's DXF with me ?
You can PM it to me if needed.

TIG

Having looked at the DXF you PM'd to me...
I confirm that it contains NO TEXT/MTEXT entities, unlike a normal CAD-originated DXF might.
There seems to very little I might call 'text' ["...FILM..."], and there are many empty objects that look like they might have been intended to be text...

I suspect that everything is in CAD 'lines' or 'polylines', and that no CAD 'text' is included in it - perhaps because of the preprocessing app you've used ?

Hi Tig,

You are correct. I will have to investigate Inkscape a little further as to why no text objects are being saved with the saveas DXF export.

Do you get a bug splat if you attempt to use importDXFtext and there are no text entities in the DXF?

Cheers,

TIG

I haven't tried it.
Away from my PC now...
BUT it should just find 'nil' text-entities to process...

Since it's a flaky DXF I suggest you find how to make a 'good' one containing the 'text'

Hi TIG.

I tried to get this plugin working on SU 2016 and wasn't successful. I go the following error in the console...

I was also importing DWG - is this an issue?

A DWG [or a DWF] file is NOT a DXF !
The former is in a proprietary 'binary' coding, the latter is in readable 'text'.
This script reads the 'text' [DXF], finds various 'TEXT' entries etc, and uses that data to recreate the SKP's equivalent 'flat' 3d-TEXT objects.

It will never work with another file type.
So export your DWG as a DXF... and try again...

TommyK

Ah, understood. My apologies.

Is it compatible with SketchUp 2016?
Thanks

TIG

It should install and work in v2016 OK.
Although it's RBZ is not yet signed for v2016, it should load OK in the default security mode - 'Unrestricted'...

Please be aware of its usage / limitations - see its first post.

nor non-ASCII DXF[x] files.

If you want to import the DXF's Geometry, and then the overlaid Text from within it, then you should ensure that the DXF import options are the same both times, AND that the CAD origin is set to be preserved - this ensures that the geometry and text overlay properly - you can always select, then move the two imported components neared to the Model's origin afterwards, if needs be.
Obviously the DXF must contain some Mtext, Dtext objects etc !

I've been getting an error that breaks your plugin for some files, TIG.
gsub': invalid byte sequence in UTF-8 (ArgumentError)`

It appears that my file had text that was not encoded in UTF-8. I added a line to your code to get it working.

txt.strip! if txt txt.chomp! if txt txt = txt.encode("UTF-16be", :invalid=>:replace, :replace=>"?").encode('UTF-8') # added this line

HI Tig,
Thanks for creating this plugin.

I've followed, i hope, all the instructions on importing but most of the text is not showing up - the ruby console, in my humble knowledge (first time of using the console) shows some promising info that there is text information in the .dxf file - see attachment.
the regular import brought in all the relevant geometry, i also have a .pdf of the .dwg file (that this .dxf file was made from) which shows there is text information.
I do get a small amount of text that shows up.(see image)
I've imported in 'mm' which is correct - they've just emailed to confirm

I was wondering, as it looks like there's info coming in, that I've done something wrong -
I've unhidden everything
I've checked all layers are visible too ......mmmmm
is there anything else i need to try?

I've sent you the .dxf file - it will be PM'ed on finishing this.....

cheers
Chris

all imported text in blue

TIG

You first import the DXF keeping the CAD origin in the import options.
This must be kept to maintain the correct location of the text in later steps.
Set the units to be whatever the DXF was saved in...
If you are not sure then mm is probably the safest ?

Now run the DXF-text importer, using the same units etc...

It can take a loooong time to import a lot of text from a DXF.

I tested your DXF and got an error after it processed the text, and then placed the first piece temporarily at the origin.
I suspect it's an issue with the way the newer Ruby methods in v2017 processes some objects.

This is an old clunky script, so I'll look at a fix asap...

cmeed

Thanks tig that's amazing.

Yes I followed your 1st post instructions. Origin etc all the same.

Thanks for looking into it!

TIG

I have now updated it and will be adding it to the PluginStore shortly...
I fixed the glitch with the new Ruby methods and also updated it somewhat, so it now runs slightly differently and is much faster [although < 1 second per text element added can still seem a long time!], and it also now reports its progress better etc...
I'll post here when it's ready.

I could also PM you your updated SKP back - 28Mb ! ...
But it could be slimmed down considerably, so it'd process quicker and give cleaner results.
For example some of the blocks of disclaimer text are constrained in CAD by using a boundary rather than newline carriage-returns, so when they import they are one long string rather than say 6 lines of text.
Either edit this kind of Mtext in CAD before making the DXF, or delete it completely as I can't see what use it is in the SKP anyway.
So perhaps fix issues with the DXF's text first and then process it yourself once v2.0 is posted ?

PS: Trimble's signing portal is down at the moment so I can't complete the update...
Watch this space...

cmeed

Tig! your're amazing!

Thanks for the advise on the Autocad and how to slim it down. I didn't create the original - i don't own any autocad software, I think Draftsight wafted past my computer a few months ago, but i have no way of altering the initial file. It was given to me as a Favour from the Studios, I won't on this occasion ask to change it, as i know I'll only bug them. I'll see them face to face tomorrow so i will ask then. but what you've done far exceeds expectation!! Amazing job cheers

TIG

Here's v2.0 http://sketchucation.com/pluginstore?pln=importDXFtext
It is now compatible with newer SketchUp's Ruby versions.
It is also now made as a signed extension.
Read the 'More Info...' link for all of the changes...

cmeed

it worked! ..... but it did'nt line up with the geometry. there was a 3 at the origin.
i have now eyeballed it refering to my pdf's and its good enough for tomorrow. I will investigate further when i have more time tomorrow and get back to you with results. imported units were the same with text and geometry....

ps it might be worth highlighting you have to put in exactly - TIG::ImportDXFtext.new - to those unfamilar with the ways of the consol. A couple of trys and i was there but I'd not put a capital I for Import. ooh its so picky .....

Great work non-the-less!!!!

TIG

I recommend you use the File menu option and keep the Console closed.
It will run faster...

Should it work with SU 2020?
Because it doesn't work for me. I saved from AutoCAD as old version of DXF as possible (2000/LT2000 DXF) and imported the file into SketchUp. All relevant layer were ON.
SketchUp only imported an empty layer on which I had my dimensions but did not import a layer on which I had text. In statistics it shows no entities.
CTRL+A results in empty selection. Also there is nothing to unhide.

Could you please take a look at the DXF, maybe try to import it and help me track the issue?
I have no other version of SketchUp to try.
