Thanks for the tips. Exporting out of my CADD software where I actually build the model is what is causing the "sloppiness" of the reversed faces. That little pigeonierre was an ancillary building on a large homesite and was at a skewed angle on the property in relation to the home. I am trying to up my game in SU because I'm being asked to submit models in that format more frequently and having to deal with the faces seems to take more time than it would to actually build the model from scratch.

That being said, I can now see the point of view behind TIG's fix reversed faces tool - that of having the model being created 100% in SU and the sloppiness coming from users not making sure the correct faces face outward before painting them with a texture. My situation is different insofar as my faces come in already textured but in the import process, many get turned around. The correct face is still painted - just reversed - and they often number in the tens of thousands! Looks like it's time to get serious about SketchUp!

Sorry about that annoying model, it was a small part of a larger project that I grabbed because it would be of a size that I could transmit. I understand now why I wasn't having any success. The materials were all attached to the "front" faces though facing in the wrong direction in many cases. That is due to the export/import process - many faces get "confused" as to which way they should face. There still appears to be no quick way to process faces that have been reversed in a large imported model. I have several other face reverser plugins, the one that seems to work best though not perfect is a view-based tool that utilizes a screen area selection. I'll try Didier's plugin. Oops, I think the one I just described IS Didier's plugin! Thanks for the help.

TIG/Dave, attached is a skp file that is an example of what I'm talking about. This model has been created in SoftPlan (my CAD program) and exported as a 3DS file, then imported into SketchUp. All I've done to it was run thomthom's CleanUp³ to reduce file size. Thanks in advance for any insight/help!

When I import an exported 3ds file from my CAD software, the materials on the model faces display at the correct scale, but the scale of the imported materials in the browser don't match: i.e., an imported material has a original sample size of 8'8" x 5'3" (a brick wall), yet in the edit window of the materials browser it has a size of 1" x 1". Anything I paint using the materials dialog with that texture display at the very small size; conversely if I change the sample size to what it should be in the material edit window; all instances of that material already on faces in the model go way out of scale! Is there an easy or quick way to sync up or save the material textures to their intended sample sizes? Right now I only use the eyedropper to add materials to surfaces in models such as these.

Ok, here is what I'm doing: I select a group or component with reversed faces on it. I then pick from the plugins drop down>TIG: Reversed Materials>Fix Reversed Materials. I get the "There is an instance of a Component in the selection! Do you want to process any faces in it?" window and choose the Yes option. After processing, the results window tells me that 0 faces have been fixed. If I triple-click on it and select all faces, then run the plugin, it still returns 0 faces fixed.

TIG, I have this plugin but the only thing that works is Delete Back Faces and Match Back Faces. What am I doing wrong?

You can save as SU8 in SU2013...

Thanks for that as well. I see now that you can "Save As" all the way back to V3!

Thanks, I had it all along! It was in the lower right corner, not the lower left, as in SU13. I was just looking in the wrong place. I have to use SU8 when creating models to import into my CAD software, which doesn't support SU13 yet.

I just installed SUv8 and I don't have the input window down at the bottom. I have forgotten how to tell the program to show it. It's probably right in front of my face! Help anyone?
