I am also getting this error in a complex model.
Any ideas what I should avoid when modeling, so it wont happen again?

@tt_su
You were right dynamic components was disabled! Now it works, thanks!

I am experiencing similar problems with Jeff.
I am on windows 64but Sketchup 2014

and yes it does that on a fresh/simple model. With all tools in joint push and pull. I also briefly noticed problems on other Fredo tools.

Thank you in advance

ok my bad...I just realised (after some years! ) that it is already supported by right clicking on a section cut and selecting "align view"

Hi m8 very nice plugin! Do you know (or anyone else ) how i can me an isometric view facing a section cut? Before your plugin we could only have front/bacl/left/right/top I am asking if there is a way to make "perpedicular to section cut" or something like that...

ty for your help and efford to create this plug in

First of all Thanks for your efford!

I am having 2 problems with this particular plugnin

1. The normal collada file from the native exporter in sketchup is about 62mb but with your is more that 250mb. Is there anything, like filenames, material names or whatever matter when exporting?
2. Importng it to Lumion doesn't seem to show up the names of the materials. Has anyone make it to work properly with lumion? Meaning lots of re-sync with correct materials?

p.s. I don't know if that matters but I am notusing "textres" in sketchup just color "materials" that I change the name (!)

Thanks for your time!

edit: I also tried with "textured" materials and some materials got idd renamed in the first time, but 1) The texture seamed to go to more surfaces than i put it 2) The names on a second export seemed to seize renamed and go to a generic material01, material03...

Although as I understanding there is not a perfect solution here. Has anyone understood what order sketchup uses in order to apply the generic material names? My first thought was alphabetical but this seems not to be the case...Plz help me....
