[Plugin] FreeDXF Importer

Jim

@John - Select "No" for the Screen Text option to use 3D text (well, 3D in only 2D.)

@Kurt - Thanks. This is what I get when importing your .dxf. It looks mostly OK, except the texts are not rotated (which I am aware but haven't fixed that yet.)

Far more than what I get! I think I could work with that if you would tell me the secret to what I may be doing wrong. Is it the text we use?
Thanks Kurt

Just try the latest version. (This link is always the most recent.)

the text is on Layer0
the model and dim lines are on the text layer,
and the dimensionline layer is empty

Yes, this is similar to what I get when using SketchUp's Pro dxf importer.

(added text rotation, btw in latest. v0.6.1)

I've been looking around at the various ruby based importers for SketchUp and I see that no one uses the Importer class. If this class is used the importer can be found in the native import list which would be very nice.

It looks like the "inputbox.rb" plugin is no longer found in bitbucket

Any alternates available?

EDIT: Never mind... Found it! For the reference of others, the source is located here: http://forums.sketchucation.com/viewtopic.php?f=323&t=19103&p=347871&hilit=+inputbox.rb+#p347871

Jim

Sorry 'bout that, Dekker. I am haphazard with my plugins - but I'm glad you found inputbox.rb

Any thoughts on the importer?

thomthom

The link to inputbox.rb is dead.

Does it handle materials in any way?

No. I don't remember seeing a "material" or "color" property for dxf entities. Isn't the color based on an entities' layer?

TIG

You are right.
A DXF file gives objects layers, and those layers have colors.
If you take the SKP layers the colors export as random colors.
Even with similar SKPs newly made layers get unconnected colors.
It's possible to rationalize a DXF by post processing it's text - I have a commercial tool I've written which uses the native DXF exporter, but where the client wanted all DXF layers to be consistently colored; so it has a 'lookup table' and ensures consistency by 'stream-editing' the DXF's text after it's made.
Another way to have materials==colors is to export a custom made DXF but ignore the SKP's layers and using each material as if it were a DXF-layer... that way objects in the DXF are then grouped by each DXF 'layer' which is really made from the SKP's material-color rather than the proper SKP-layer...

Dec 2011 - I have removed the external dependency on my inputbox.rb - it is no longer required as a separate download. Also, I attached the download to the first post of this topic rather than linking to an external site. Hopefully, these changes will make it easier for folks to try.

Is DXF extendable? I wonder if AutoDesk writes DXF with extra material info..?

TIG

A DXF can include all the types of data that you get in a DWG file itself.
However, as objects have layers and layers have colors, that's it.
You can assign attributes to objects containing additional info, so you can pass [otherwise-unused] data... but how that's useful later on is questionable.

I'm trying to find a good way to export a Revit model to SketchUp.

I have tried exporting to FBX and then use Autodesk's converter utility to convert to DAE - but that fails on import every time on any model in SU. Fail in Blender as well.

DWG and DXF import in SU - but uses layer material, as you describe. However, if I import the same DXF into another Autodesk application like 3DS - the materials are like how they where defined in Revit. And that is why I'm exploring this topic.

Jim

FreeDXF imports acad layers as SketchUp Groups, so it may be possible to color the Groups according to their acad layer color number.

It doesn't seem to work for me. I have Sketchup 8, with the new maintenance pack. It shows up in the plugins menu, then when executed it asks for arc segments, etc. When I click ok, nothing shows up. I'm using DWGeditor 2007 to create dxfs in ASCii 2007 format.

Can you post or send the file?

%(#4000FF)[I've got a script not loading error on start with free version 8.0.4811.
I would assume I had the files in the right places although I can't see the folder layout image in the script posting - just an image name.
Bound to be missing the obvious, be grateful if someone could nudge me in the right direction......cheers.

Ooh one other question......Can I load the SU pro trial in tandem with my free version without bu#@ering it up or compromising the trial?....would quite like to see what I'm missing.]

TIG

Does you Sketchup Plugins folder look like this ?

%(#0000FF)[ Hi Tig
Thanks for responding. My directory looks correct, are there any dependencies I may be missing?
I did read something in an earlier incarnation about the file naming system having to be basic without spaces ('joliet' stuff!!), it looks a bit more like an issue in that direction perhaps, paths & stuff....he says clutching at straws!!

%(#0000FF)[.......The file is definitely there!
Being skint takes up a lot of my time! Just can't justify the Pro version though so your help is much appreciated!]
