Thank you for posting.
The (Error Loading File rubysketch_plusspec/plusspec.d/tools2/tools/slab-recess-edit-tool.rb
Could not find included file 'rubysketch_plusspec/plusspec.d/tools2/tools/slab-recess-edit-tool.rb') is something that is appearing in the latest version of SketchUp as was said.
We have done many tests on this and there will be no problem with any part of the slab. We are still unsure as to why this is appearing in the latest version of SketchUp but no other version. This is not actually a problem it is just load errors that are appearing. I will keep you updated on our progress.
Please before using any tools with PlusSpec 2016, run a SYNC. By running a SYNC it will download all of your materials. The roof errors will be fixed when you do this and you should stop receiving bug splats. If you are still receiving issues after running a SYNC please send an email to - firstname.lastname@example.org
and send myself a screen capture video of what is happening, Ill be able to help.
If you do have any problems it is best to post on the forum as I check them everyday (Excluding Weekends) or to email me personally.
Please let me know if I have helped you out.
