[Plugin] KML Tools (2.0.0-beta) — updated 31.05.2013

dawrightau

Hi

This is a great tool thank you. I am using it to import contour lines but am having an issue with failing to import all data with more detailed contours (ie 1 metre contours for a small area).

The KML file containing contours is only 152 k but when using the plug in fetches elevation data and then imports about 1/3 of the contour lines but then it hangs on a dialog title "Progess" importing linestrings which is all in blue and no further data is imported.

Is this a size / number of entities / memory limitation? Even though detailed it is not huge.

Any help would be appreciated.

Thanks regards

David

TIG Thanks for your PM reply :

I know of no size limit.
Are you sure Sketchup has hung and not just slowed down?
What does the Task Manager show ??

TIG

Re your questions :

Sketchup doesnt seem to have "Stopped responding" according to the task manager.

The first third of the contours come in quickly. After trying a couple of times I left it sit for a couple of hours but no further activity other than a blue progress bar sitting at 100%.

I did find a suggested size kml file limit of not much more than 200KB, otherwise Sketchup will go very slowly.

I have attached the file in question.

For other forum members interest, I also found another tool to import shapefiles into sketchup at the following URL :

 [http://www.strategis.nl/StrateGisSoftware/SGGISShapeImporterForSketchup.zip](http://www.strategis.nl/StrateGisSoftware/SGGISShapeImporterForSketchup.zip)

This imports all the contours from a shapefile into sketchup in instant (which suggests to me the KML file shouldn't be too big for sketchup).

However unlike KML Import, GIS Shape Importer does not georeference the contours or group individual contours with the elevation height as the group name. GIS Shape Importer as the name suggests also cannot export to shapefiles whereas KML Import can export as well. These features in KML Import are nice features which allows automation of height adjustment of the contours to create a tin file and export the elevated contours as well.

Unfortunately because of the import problem I cant use KML import for this at the moment so am doing it all painfully / manually. However at least with GIS Shape importer I am able to progress in the meantime.

If anyone can test my file and see if they are getting the same problem and suggest a solution that would be much appreciated.

Hi,
I found the problem and fixed it. Thanks for attaching the file with which the problem occured.

Importing big kml files can be slow because they are in xml format and there is no efficient way in SketchUp/Ruby to do it faster. I think shapefiles are in a binary format, so if there is a direct importer it could be faster.

Hi Aerilius,

Thanks for getting back to me.

Glad you were able to fix it but how do I get access to the fix?

I checked the plugin download site and the date of the download plugin file is

   3/07/2011 7:05 PM

Be grateful to get this working.

Thanks again.

Cheers

Hi,
the first post of this thread has version 1.4.9 (29.04.2012). If it is also distributed on another site, then I don't have access to update it there.

dawrightau

Thanks Aerilus,

The update worked perfectly and immediately (essentially no delay).

For some reason I thought the official site was http://extendsketchup.com/plugins/kml-tools/

The logical spot as you say was at the beginning of this forum.

Thanks again.

Kind regards

David Wright

I had done more than a week testing and hadn't imagined that there still could be such issues.
Now I've uploaded a new version. I found a work-around to drop the IE8 requirement and fixed some more things. I hope it works this time.

just wanted to say thank you so much for making this tool available

Hi Again Aerilus

The plugin is working fine for some kml files but for some reason inst working with others.

The ones that work have elevation data generated when they are created.

I tried importing a simple kml file with no elevation data and I get a white dialog box progress and no progress (please see hayrack boundary.kml)

I added 10 m vertices to the polygon and added elevation data to them and now get a dialog box with 50% progress where it stops (please see hayrack boundary with elevation.kml)

Any assistance would be appreciated.

Regards

David

I got an KML file I'm trying to import, but I'm getting errors:

This plugin is unfortunately very error-prone because it was my second plugin and it uses RegExps to parse xml (I hope I find a better way to handle xml, rexml didn't prove to perform better). I'll take a look at this whern I'm at home!

thomthom

You're using a webdialog for the import - you can use the XML parsing capabilities of the web-browser:
http://www.w3schools.com/xml/xml_parser.asp

If you use jQuery it's very simple:
http://stackoverflow.com/questions/649614/xml-parsing-in-javascript

Aerilius

That sounds interesting. Javascript isn't the fastest either, but this strategy probably doesn't use the script language's string functions but the browser's compiled code.
I once ported the plugin (partly) to ReXML and ran performace tests (more reliable but 107% slower, ReXML is pure Ruby and I wanted to avoid gems). So I'll try it with this again.

thomthom

ReXML is one of the slowest XML solutions - but as you mention it's pure Ruby. The others require some binaries. I want a Ruby parser because some times I don't have a WebDialog UI for plugins that has use of XML.

Hi David,
I tried both files in a non-geolocated model and in a geolocated model (with terrain) and they both work for me (plugin version 1.4.6). I have no idea what could go wrong. When you open the Ruby Console before running th plugin, do there appear some error messages?

with terrain

I'm not sure what causes this problem. It looks like one point of a polygon could not be parsed (nil) or a polygon has less than 3 points. Off the bat I would have tried:

while a.length > 3 # replace line 754

return if outerLoop.length < 3 # insert after line 311

Thanks for getting back to me Aerilius,

I am using 1.4.9 being the version you updated to fix the part loading issue of mine in a previous post.

There is an error in the ruby console. This is the ruby console messages for the harack boundary file :

Also a question

When one kml file (that imports ok) has been imported it is not possible to import another. A new instance of sketchup has to be opened to use the tool again.

Is this how it is or should I be able to import multiple kml files, one after another?

Thanks

This should not happen, one should be able to import any amount of kml files ninto the same model.

I think I found the issue and have almost fixed it (I will finish and release an update this evening).

I uploaded a new version!
