Custom importer - setting options

tireddude

Hi. I'm writing a custom KMZ importer mainly because SU's built in KMZ importer/exporter won't read/write the KML <orientation></orientation> tag for tilt, roll and heading angles causing KMZ import-export operations to make models "misplaced" in Google Earth. However, that is really not what this post is about. Please read on.

My custom importer is doing this (among other things)

class AcustomImporter < Sketchup;;Importer

but i'm having troubles setting options. I need to be able to set "Validate Kmz file" and "Merge Coplanar Faces" option from code. When i use my custom importer, it is reading whatever values the user last set in the options dialog for Google Earth Files importer!

I also found out that these options are read by SketchUp from the windows registry upon SU startup and loaded into some (at least to me) hidden variable. Key is HKEY_CURRENT_USER\Software\SketchUp\SketchUp 2014\Kmz Importer. When the user changes options, the new values are written immediately to the Windows Registry. If i try to change in the registry and open the options dialog again, values are NOT updated there.

How can i access these options from code? And why are they affecting my custom importer? Can't find anything in the API for this. It is like

Sketchup.active_model.import filePath , showSummary

should have a few more arguments.

Any help on this matter would be much appreciated.

Want to manipulate these options from code.

You made an importer from scratch? In which case I don't see why the SU settings should affect your code. I'd be hard to say what is going on without seeing your code though.

Oh... hang on. Is your importer calling The Ruby API Model.import method?

Yes it its. I'm making an ugly workaround for the missing <orientation> info. Basically using the built-in importer but also unzipping the KMZ and reading the KML file myself and making the necessary adjustments (tilt, rotation, heading) to the geometry in the model (according to angles from KML) before using the built-in exporter. Some other changes are also made but they are unrelated.

Before this i've tried for days to fetch those angles somewhere in Sketchup but i finally came to the conclusion that the importer is broken - correct me if i'm wrong.

Thanks for the quick reply!

I don't know much about the importers themselves. I have to ask someone else on the team - they are not online yet as they are all in the US.

Ok thanks. Please post here when/if you get more information. It would be great if both problems could be solved somehow.

The Sketchup::Importer#do_options() example is totally wrong. (It is the terse, almost worthless, example for id().)

The API should explain how options are used and stored.

Any news on this?

Sorry about the delay in response. The API is currently missing the ability to set import options. I ensured we had a feature request for it filed.

But it appear that what you do is a workaround for an issue with the existing importer. Would you mind describing the issue in detail and provide samples that illustrate?

This shows a couple of problems i have ran into:

Start Sketchup
Make a cube
Geolocate model
Save as SKP
Export as "test_model.kmz"

in KML now <Orientation><heading>-0</heading><tilt>0</tilt><roll>0</roll></Orientation>
Try kmz in Google Earth - OK
Close Sketchup
Start Sketchup
Import test_model.kmz
Modelinfo -> Geo-location "This model is not GeoLocated" it says
Check dictionaries (my own script - screenshot on this)
Model has two(!) georeference dictionaries
Export to KMZ again "test_model_imp_kmz+exp_kmz.kmz"
Test in Google Earth even tho SU says "not geolocated" - OK (ends up in exact same spot as the first one)
Delete all but last GeoReference dictionaries in SU with own script
Check dictionaries
Only one GeoReference entry exist now (see screenshot)
Modelinfo -> Geo-location "This model is accurately geolocated"
=== END OF A PROBLEM WITH DUPLICATE GEOREFERENCE DICTIONARIES MAKING SU SAY "MODEL NOT GEOLOCATED" EVEN IF IT IS ===
Close Sketchup
Unzip "test_model.kmz"
Change under <Model> .... <Orientation> to random values
<Orientation><heading>33</heading><tilt>-70</tilt><roll>-20</roll></Orientation>
Zip (with changes) and rename to "test_model_MOD.kmz"
Test in Google Earth "test_model_MOD.kmz" (should be "flying" now - OK)
Start Sketchup
Import "test_model_MOD.kmz"
Export to "test_model_MOD_imp_kmz_exp_kmz.kmz"
Test in Google Earth "test_model_MOD_imp_kmz_exp_kmz.kmz" (should be flying but it is NOT)
Look in the KML in "test_model_MOD_imp_kmz_exp_kmz.kmz"
<Orientation><heading>-0</heading><tilt>0</tilt><roll>0</roll>
!! THE CHANGES ARE LOST !!

So this is basically why i need to parse the KML. I get models where roll/tilt/heading is set and when changes are made inside Sketchup and then exported to KMZ again, model ends up in wrong place in Google Earth. Well, its not in wrong place, its just rolled/tilted/rotated wrong actually but it looks like it is in the wrong place.

I will attach the files too.

Created and geolocated inside Sketchup then exported

Imported then exported

test_model.kmz modified heading roll tilt under the <Model> tag in KML

Modified imported then exported

Duplicate GeoRef dictionaries

After remove of duplicate GeoRef dictionaries

I forgot to say thankyou for this. Hope it gets sorted out.
